Step-by-step explanation:

One bagel costs 155 cents.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question.

Let x = cost of one bagel

y = cost of one toast

z = cost of one muffin

If two pieces of toast and a bagel costs $3.15, then 2y + x = 3.15.

2y + x = 3.15   ⇒   x = 3.15 - 2y     (equation 1)

If a bagel and a muffin costs $3.30, then x + z = 3.30.

x + z = 3.30     (equation 2)

Substitute equation 1 to equation 2.

x + z = 3.30     (equation 2)

3.15 - 2y + z = 3.30   ⇒   z = 0.15 + 2y      (equation 3)

If a piece of toast, two bagels, and three muffins costs $9.15, then

y + 2x + 3z = 9.15     (equation 4)

Substitute equations 1 and 3 to equation 4.

y + 2x + 3z = 9.15     (equation 4)

y + 2(3.15 - 2y) + 3(0.15 + 2y) = 9.15

y + 6.30 - 4y + 0.45 + 6y = 9.15

3y = 2.4

y = 0.8

Substitute the value of y to equation 1.

x = 3.15 - 2y     (equation 1)

x = 3.15 - 2(0.8)

x = 1.55

Hence, the cost of one bagel is $1.55 or 155 cents.

The number that cannot be a factor of AB is 20.

What is prime factorization?

The process of determining which prime numbers combine to form the original number is known as "prime factorization."

The prime factorization of 44 is 2211, and the prime factorization of 27 is 333.

Therefore, A could be any of the factors of 44, which are 1, 2, 4, 11, 22, and 44. Similarly, B could be any of the factors of 27, which are 1, 3, 9, and 27.

To find which number cannot be a factor of AB, we need to consider all the possible combinations of A and B and their factors. The product of A and B will have all the prime factors of A and B.

The prime factorization of AB will include 2, 3, and 11.

Yes, Ratio 18:3 compare to 6:1 are equivalent ratios. The constant value is equal to 3.

An ordered pair of numbers a and b, represented as a/b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

Ratio: 18:3 Value of the Ratio:  18/3 if we divide both sides by 3,  we can say the value is 6/1.

The value is equal to 6. Here:

The ratio 18:3 is equal to the ratio 3:1

Here,

18:3 = \(\frac{18}{3}\)

6:1 = \(\frac{6}{1}\)

Thus, distribution is a function that shows the possible values for a variable and how often they occur and categorical values are summarized by counts and/or percents

In statistics, the distribution is a function that shows the possible values for a variable and how often they occur.

The distribution of a data set is the shape of the graph when all possible values are plotted on a frequency graph. Usually, we are not able to collect all the data for our variable of interest. Therefore we take a sample. This sample is used to make conclusions about the whole data set.

The categorical variable is a data in which individuals are placed into groups or categories.

One way to summarize categorical data is to simply count (frequency), or tally up, the number of individuals that fall into each category. Another way is to show the percentage of individuals who fall into each category, thereby creating a relative frequency.

Answer:

The largest digit to be placed on the blank in the 5_,310 to make it divisible by 6 is 9 to give 59,310

Step-by-step explanation:

The given question requires the digit to be placed in the space left blank in 5_,310 to make it divisible by 6

To answer the question, we note that given that 51,000, 54,000, 57,000, and 60,000 are divisible by 6, and that 310 is not divisible by 6, we have

1,310 is not divisible by 6, but 2,310 is divisible by 6

Therefore, the complete number will be 57,000 + 2,310 = 59,310 which gives;

59310/6 = 9,885

Therefore, the complete number is 59,310, and the required digit is 9.

Answer:

The missing fraction is 6/12

(you can further simplify this but the question requires that you don't do that)

Step-by-step explanation:

To add fractions easily, their denominators should have the same value, so the denominator should be 12,

Then, to get 16 in the numerator, we need to find a number that on adding to 10, gives 16, or,

10 + x = 16

x = 16 - 10

x = 6

So, the numerator should be 6

so we get the fraction, 6/12

We can also solve it in an alternate way,

\(10/12 + x = 16/12\\x = 16/12 - 10/12\\x = (16-10)/12\\x = 6/12\)

The magnitude of the net electric field at point P due to the particle is 0 . explanation is given as

let us assume that , The charges of the four particles and the distance are given then on understanding the  concept of electric field  at electrostatics concept. on using the concept of the electric field at any given point, then production of  individual electric field by a charge. and we known the concept of superposition law, on applying the law  we  get the value of the electric field in its direction and this shows the determination of   the net electric field at that point.

The magnitude of the electric field,  

E = q * R

where R = The distance of field at  point from the charge, and q = charge of the individual particle

According to the superposition principle, the electric field at a single point due to more than one charges present ,hence on calculation of net electric field  we get the origin of the coordinate system  which is placed at point P and the y-axis is situated and oriented in the direction of the charge,  (passing through the charge, ). The x-axis which  is perpendicular to the y axis, and thus passes through the identical charges, then the  individual magnitudes of an electric field is due to the charges are demonstrated by using the absolute signs of the charges. Now let us assume that the point charge which  being positive i.e  ( q > 0), we can see that the contributions coming from each charge gets cancel to each other. Therefore the net electric field in the direction of the y-axis is given using equation as  E= 0

hence the net electric field is zero .

Answer:

Answer:

The perimeter of a parallelogram is 30cm.

Step-by-step explanation:

From the question , the given area of a parallelogram is 36 cm².

But the area of a parallelogram can be calculated using below formula

Area = base * height

From the question the distances that exist between the point of intersection of the diagonals and the sides are 2cm and 3cm respectively

There is the same distance between point of intersection of the diagonals and the opposite sides then,

The base of the side with 4cm can be calculated as

ha= 2+ 2= 4cm

But area can be calculated as A= base × height

36= b1 × h1

36=b1 × 4

b1= 9cm

The base of the other side can be calculated with 6cm height

h2= 3+3=6cm

A= b2× h2

36= b2 ×h2

36= b2× 6

b2= 6cm

Then the perimeter of the parallelogram can be calculated as

P= 2(b1 + b2)

= 2(6+9)

= 30cm

Hence,the perimeter of the parallelogram is 30cm

There are five possible outcomes: H, TH, TTH, TTTH, and TTTT, where H stands for head and T stands for tail. Among these outcomes, H occurs only once,

(a) The number of heads before the first tailWhen tossing a fair coin four times, we need to determine the probability of tossing a head before the first tail occurs.

Here, we can assume that each toss is independent, meaning that the outcome of one toss does not heads the outcome of the other tosses.

There are five possible outcomes: H, TH, TTH, TTTH, and TTTT, where H stands for head and T stands for tail. Among these outcomes, H occurs only once,

TH occurs twice, TTH occurs twice, and TTTH and TTTT each occurs only once. Thus, the frequency function for the number of heads before the first tail can be determined as follows:X: 0 1 2 3 4f(X): 1 2 2 1 0The cumulative distribution function (CDF) can be calculated by summing up the probabilities of each outcome up to and including the current value of X:

FX: 0 1 2 3 4F(X): 0 1/16 5/16 13/16 1(b) The number of heads following the first tailSimilarly,

we can determine the frequency function and the cumulative distribution function for the number of heads that occur following the first tail.

Again, we can assume that each toss is independent, meaning that the outcome of one toss does not affect the outcome of the other tosses.

There are four possible outcomes: T, HT, HHT, and HHHT, where H stands for head and T stands for tail. Among these outcomes,

T occurs only once, HT occurs twice, HHT occurs twice, and HHHT occurs only once. Thus, the frequency function for the number of heads following the first tail can be determined as follows:

Y: 0 1 2 3f(Y): 1 2 2 0The cumulative distribution function (CDF) can be calculated by summing up the probabilities of each outcome up to and including the current value of Y:GY: 0 1 2 3G(Y): 0 1/2 3/4 1

Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations. This implies that the simultaneous equations have a common solution.

We use different methods to solve simultaneous equations. Some of the common methods are:

By substitution method

-7x + -5y = 15 ----- 1

7x + 3y = 12 ----- 2

from equation 1

7x = -15 -5y ----- 3

substitute 7x in equation 2

-15 - 5y + 3y = 12

-2y = 12 + 15

-2y = 27

y = -27/2

To find x, substitute y in equation 3

7x = -15 - 5(-27/2)

7x = -15 + 135/2

Multiplying both sides by 2

h(a) = 3a

To find g(h(8)), we need to first evaluate h(8), and then plug that result into g(a) and simplify.

h(a) is defined as 3a, so h(8) = 3(8) = 24.

Now we can plug in 24 for a in g(a) and simplify:

g(a) = 4a - 2
