2 3/4 of 500grams in step by step calculator
Answers
Answer:
To calculate 2 3/4 of 500 grams, follow these steps:
1. Convert the mixed number to an improper fraction:
2 3/4 = (2 x 4 + 3)/4 = 11/4
2. Multiply the improper fraction by 500:
11/4 x 500 = (11 x 500)/4 = 2,750/4
3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:
2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2
Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Point M is the midpoint of AB. If the coordinates of A are ( -3 , 6 ) and the coordinates of M are ( -5 , 2 ), what are the coordinates of B? (reference sheet on the left side)
Answers
The coordinates of B are (-7,-2).
What do you mean by x and y coordinates?
The x and y coordinates are a component of the x-axis and y-axis in a 2D space in the Cartesian coordinate system. The x and y coordinates for a point in space are expressed as an ordered pair (x, y). The position of the point on the x-axis is shown by the first number, while its location on the y-axis is indicated by the second number.
According to the given data in the question,
if M is the location where line segment AB meets its midpoint.
Then, we will using the midpoint formula,
\((-5,2)=(\frac{-3+x}{2},\frac{6+y}{2})..............(1)\)
Putting the x-coordinates in (1),
\(-5=\frac{-3+x}{2}\\ -10=-3+x\\-10+3=x\\x=-7\)
Similarly, putting the y-coordinates in (1),
\(2=\frac{6+y}{2} \\4=6+y\\4-6=y\\y=-2\)
Hence, the coordinates of B are (-7,-2).

what is the probability a randomly selected pregnancy lasts less than 260 days?
suppose a random sample of 20 pregnancies is obtained. what is the probability that a random sample of 20 pregnancies has a mean gestation period of 260 days or less?
what is the probability that a random sample of 50 pregnancies has a mean gestation period of 260 days or less?
Answers
For p(x<62) and p(x>68), we can use the z-score formula to calculate the probability.
p(x<62), the z-score formula is (62-64)/18 = -0.11.
p(x>68), the z-score formula is (68-64)/18 = 0.22.
The rest answer are mentioned below with calculation.
What is z-score formula?It is (X-μ)/σ, where X is the value we are evaluating, μ is the mean of the population, and σ is the standard deviation of the population.
For the first two questions, p(x<62) and p(x>68), we can use the z-score formula to calculate the probability. The z-score formula is (X-μ)/σ, where X is the value we are evaluating, μ is the mean of the population, and σ is the standard deviation of the population.
For the first question, p(x<62), the z-score formula is (62-64)/18 = -0.11. This means that the probability of x being less than 62 is 0.3767 (from the z-score table).
For the second question, p(x>68), the z-score formula is
(68-64)/18 = 0.22.
This means that the probability of x being greater than 68 is 0.5987 (from the z-score table).
For the third question, the probability that a randomly selected pregnancy lasts less than 260 days can be calculated using the z-score formula.
The z-score formula is (260-266)/16 = -0.375. This means that the probability of a randomly selected pregnancy lasting less than 260 days is 0.3296 (from the z-score table).
For the fourth question, the probability that a random sample of 20 pregnancies has a mean gestation period of 260 days or less can be calculated using the Central Limit Theorem.
Since the sample size is 20, the standard deviation of the sample is
16/√(20) = 4.
The z-score formula is (260-266)/4 = -1.5.
This means that the probability of a random sample of 20 pregnancies having a mean gestation period of 260 days or less is 0.0668 (from the z-score table).
For the fifth question, the probability that a random sample of 50 pregnancies has a mean gestation period of 260 days or less can be calculated using the Central Limit Theorem.
Since the sample size is 50, the standard deviation of the sample is
16/√(50) = 1.83
The z-score formula is (260-266)/1.8 = -3.3.
This means that the probability of a random sample of 50 pregnancies having a mean gestation period of 260 days or less is 0.0062 (from the z-score table).

Winston has just received his monthly credit card statement. He placed eight charges on his card in the last month with a mean of $39.77 Per charge. He knows that seven of the charges were as follows determine the amount of the eighth charge
Answers
Given:
Number of charges = 8
Mean charge = $39.77
Other seven charges: $46.06, $39.70, $47.29, $39.13, $44.66, $38.53, $46.89
Let's find the eight charge.
Apply the formula for mean:
\(mean=\frac{sum\text{ of charges}}{number\text{ of charges}}\)Let x represent the eight charge.
We have:
Sum of charges = $46.06 + $39.70 + $47.29 + $39.13 + $44.66 + $38.53+ $46.89 + x = $302.26 + x
Thus, we have:
\(\begin{gathered} 39.77=\frac{302.26+x}{8} \\ \\ \text{ Multiply both sides by 8:} \\ 39.77*8=\frac{302.26+x}{8}*8 \\ \\ 318.16=302.26+x \\ \end{gathered}\)Solving further:
Subtract 302.26 from both sides
\(\begin{gathered} 318.16-302.26=302.26-302.26+x \\ \\ 15.9=x \\ \\ x=15.9 \end{gathered}\)Therefore, the eight charge is $15.90

Find the slope of the line -2x - 5y = 10
Answers
Answer:
-2/5
Step-by-step explanation:
To find the slope of an equation, we first convert the equation into Slope-Intercept Form: y = mx + b, where m is the slope, and b is the y- intercept.
=================================================================
Add 2x to both sides. [Addition Property of Equality]
-2x - 5y = 10
+2x +2x
-------------------
-5y = 2x - 10
Divide -5 on both sides. [Division Property of Equality]
-5y/-5 = 2x/-5 - 10/-5
y = -2/5 x + 2
Comparing to y = mx + b form, we see that our m value, or slope is -2/5
--------------------------------------------------------------------------------------------------------------
m= -2/5

A student was asked to give the exact solution to the equation
22x+4-9(2) = 0
The student's attempt is shown below:
22x+49(2)=0
22x+24-9(2) = 0
Let 2* = y
y²-9y+8=0
(y-8)(y-1)=0
y = 8 or y=1
So x = 3 or x = 0
(a) Identify the two errors made by the student.
(b) Find the exact solution to the equation.
Answers
(a) The errors made by the student are:
Incorrectly expanding 49(2) as 24 instead of 98.
Mistakenly factoring the quadratic equation as (y - 8)(y - 1) instead of
\(y^{2} - 9y + 8.\)
(b) The exact solution to the equation is x = 7/11.
(a) The student made two errors in their solution:
Error 1: In the step \("22x + 49(2) = 0,"\) the student incorrectly expanded 49(2) as 24 instead of 98. The correct expansion should be 49(2) = 98.
Error 2: In the step \("y^{2} - 9y + 8 = 0,"\) the student mistakenly factored the quadratic equation as (y - 8)(y - 1) = 0. The correct factorization should be \((y - 8)(y - 1) = y^{2} - 9y + 8.\)
(b) To find the exact solution to the equation, let's correct the errors made by the student and solve the equation:
Starting with the original equation: \(22x + 4 - 9(2) = 0\)
Simplifying: 22x + 4 - 18 = 0
Combining like terms: 22x - 14 = 0
Adding 14 to both sides: 22x = 14
Dividing both sides by 22: x = 14/22
Simplifying the fraction: x = 7/11
Therefore, the exact solution to the equation is x = 7/11.

la edad de Ana es la mitad de jose y dentro de 10 años seran dos tercios ..cual es la edad de jose
Answers
La edad actual de José es de 30 años.
Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.
La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.
Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.
Resolviendo esta ecuación, podemos simplificarla y llegar a: 2(x + 10) = 3[(1/2)x + 10].
Al resolver la ecuación resultante, encontramos que x = 30.

Mbali walks to the lake every third day. Nqabisa walks to the lake every
fourth day. Calculate how often they will walk to the lake on the same day
Answers
Step-by-step explanation:
we need to find the LCM, the least (or lowest) common multiple, of 3 and 4.
that means the smallest number that can be divided by 3 and by 4 without remainder.
and that is simply in our case 3×4 = 12.
so, every 12th day they will walk to the lake "together" (on the same day).
FYI - formality the LCM is found e.g. by prime factorization.
starting with the smallest prime number (2) both numbers are divided by the prime number, if there is no remainder. the quotient is then again divided by the prime number. if there is a remainder, then the next higher prime number is taken for the division.
this goes on until we get a quotient of 1.
the LCM is then the product of the longest streaks of the products of the same prime numbers.
example LCM of 56 and 50
56 ÷ 2 = 28 (0 remainder)
28 ÷ 2 = 14 (0 remainder)
14 ÷ 2 = 7 (0 remainder)
7 ÷ 2 has a remainder, so the next prime number (3)
7 ÷ 3 has a remainder, so the next prime number (5)
7 ÷ 5 has a remainder, so the next prime number (7)
7 ÷ 7 = 1 finished
50 ÷ 2 = 25 (0 remainder)
25 ÷ 2 has a remainder, so the next prime number (3)
25 ÷ 3 has a remainder, so the next prime number (5)
25 ÷ 5 = 5 (0 remainder)
5 ÷ 5 = 1 finished
the longest streaks of prime number products :
2×2×2 = 8
5×5 = 25
7 = 7
the LCM = 8×25×7 = 1400
please consider, this is NOT 56×50 = 2800.
the LCM is not automatically just the product of both numbers. this product is a common multiple, true, but not always the smallest.
in our case here with 3 and 4
3 ÷ 2 has a remainder, so the next prime number (3)
3 ÷ 3 = 1 finished
4 ÷ 2 = 2 (0 remainder)
2 ÷ 2 = 1 finished
the longest prime number product streaks :
2×2 = 4
3 = 3
the LCM = 4×3 = 12
so, in this case the LCM is the direct product of both numbers.

So that would make the formula: (3.14)R^2-(3.14)r^2 = A
The only unknown variables that you need to find are the radii of the two circles
The smaller circle:
You are given the diameter, and the diameter is 1/2 the radius,
so r= 1/2(11.25) = 5.625
The larger circle:
You are given the width, which is the total added onto the diameter of the smaller circle so:
(11.25+3.75)/2=7.5
and now that you know R, you can plug into the equation found at the start: (3.14)R^2-(3.14)r^2 = A
(3.14)(7.5^2)-(3.14)(5.625^2)=A
A=176.71-99.35
