Find Each Missing Length To The Nearest Tenth

Answers

Answer 1

Answer:

Step-by-step explanation:

Let's do this step by step!

The hyponteuse is 7.7 because it is the longest side of a 90 degree angle.

the formula for this would a^2 + b^2 = c^2

 3.3^2 + b ^2 = 7.7^2

 10.89 + b^2 = 59.29

- 10.89            - 10.89       subtract from both sides

  b^2 = 48.4

\(\sqrt{b} = \sqrt{48.4} \\\)

b = 6.95701085237

round to the nearest tenth ---> 7

A chef draws cookies randomly from a box containing 6 cookies of the same shape and size. There is 1 chocolate cookie, 3 almond cookies, and 2 butter cookies. He draws 1 cookie and then draws another cookie without

replacing the first one. Find the probability of picking 1 almond cookie followed by another almond cookie. Show ALL your work AND write your answer as a fraction, decimal, and percent

Answers

Answer:

For Part A:

The total of 1+4+3 marbles is 8 marbles

P( blue ) = blue /total = 4/8 = 1/2

He replaces it, so there are still 8 marbles in the bag

P(blue 2nd draw) = blue /total = 4/8 = 1/2

P(blue,replace, blue) = 1/2*1/2 = 1/4

For Part B:

1 choc chip, 3 almond, 2 butter. 6 total cookies.

probability of picking 1 almond on first pick : 3/6 which is 1/2

without replacement

probability of drawing another almond : 2/5

Probability of drawing 1 almond followed by another (without replacement ) is:

3/6 * 2/5 = 6/30 = 1/5

The Slope is 1/2

Step-by-step explanation:

Rise/Run

Rise 1

Run 2

Answer:

0.5 or  1/2

Step-by-step explanation:

For the slope of the line you use the equation.

M=Raise/Run which is equal to the equation y2-y1 / x2-x1

First you need to determine your points. for example (0,1) and (10,6).

which would make the equation when filled out.

6-1 / 10-0

six - one = five

10-0 = ten.

five divided by ten equals 0.5. therefore the slope would be 0.5 or 1/2.

Find the slope of -9, -6 and -8, 7

Answers

Answer:

A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Seth made a mistake and used 5 cups of flour. How many cups of milk should he use to keep the amount of ingredients proportional?

Answers

Answer:

2.5 cups of milk will make his ingredients proportional.

Step-by-step explanation:

Since he used five out of the three cups of flour he was supposed to use, you can use that as the fraction: 5/3.

Since 5/3 was used on the flour, it also has to be used on the milk

To apply it to the milk, you just multiply 5/3 × 1.5 cups of milk, which gets you 2.5 cups of milk

*Multiplying by a fraction also means of.

Example: 1/2 × 4 = 2 because two is 1/2 of 4

3(x+ 7) = -12
x + 7 =
X =

3(x+ 7) = -12x + 7 =X =

Answers

Answer:

x = - 11

x + 7 = -4

Step-by-step explanation:

\(3(x + 7) = - 12 \)

Multiply each term in parentheses by 3

\(3x + 3 \times 7 = - 12\)

Multiply 3 and 7

\(3x + 21 = - 12\)

Move the constant to the right side and change the sign

\(3x = - 12 - 21\)

Find the sum of negative numbers

\(3x = - 33\)

Divide both side by the same number

\(x = - 11\)

= x + 7

= -11 + 7

Add the term - 11 + 7

= -4

Hey ! mate

Answer:

x + 7 = -4

x = -11

Step-by-step explanation:

In this question we have given an equation that is 3( x + 7 ) = -12 and we have asked to find the value of x + 7 and x .

We are starting our solution from here :

\( \longmapsto \: 3( x + 7 ) = -12 \)

Transposing 3 to right hand side :

\( \longmapsto \: x + 7 = \frac{ - 12}{3} \)

Now , dividing -12 by 3 :

\( \longmapsto \: \blue{\boxed{x + 7 = -4}}\)

Therefore , value of x + 7 is - 4 .

Now ,

\( \longmapsto \:x + 7 = - 4\)

Transposing 7 to right hand side :

\( \longmapsto \:x = - 4 - 7\)

\( \longmapsto \: \blue{ \boxed{x = - 11}}\)

Therefore , value of x is -11 .

the house was in the shape of an __________ , eight separate bedrooms on each side

Answers

The house was in the shape of an octagon, with eight separate bedrooms on each side.

The house described in the statement has an octagonal shape. An octagon is a polygon with eight sides, characterized by its eight equal angles. In this case, each side of the house corresponds to one of these angles, resulting in eight separate bedrooms on each side of the octagonal structure.

The choice of an octagon as the shape of the house can have various implications. Octagonal buildings are often admired for their unique architectural design and aesthetic appeal. The shape provides symmetry and balance, allowing for an interesting and visually pleasing structure. Additionally, an octagonal layout can offer practical advantages in terms of space utilization and room distribution. In the case of the house described, each side of the octagon accommodates a separate bedroom, providing privacy and ample living space for its occupants. The symmetrical arrangement of the bedrooms around the central area of the house could create a harmonious and well-organized living environment. Overall, the octagonal shape of the house with eight separate bedrooms on each side offers both architectural and functional benefits.

(a) Can a confidence interval for true average lifetime be calculated without assuming anything about the nature of the lifetime distribution?

(b) Calculate and interpret a confidence interval with a 99% confidence level for true average lifetime. [Hint: mean=1191.6, s=506.6.]

Answers

(a) Yes, a confidence interval for the true average lifetime can be calculated without assuming anything about the nature of the lifetime distribution.

(b) Using the given data, we can calculate a confidence interval with a 99% confidence level for the true average lifetime, with a mean of 1191.6 and a standard deviation of 506.6.

(a) It is possible to calculate a confidence interval for the true average lifetime without assuming any specific distribution. This can be done using methods such as the t-distribution or bootstrap resampling. These techniques do not require assumptions about the underlying distribution and provide a reliable estimate of the confidence interval.

(b) To calculate a confidence interval with a 99% confidence level for the true average lifetime, we can use the sample mean (1191.6) and the sample standard deviation (506.6). The formula for calculating the confidence interval is:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

The critical value depends on the desired confidence level and the sample size. For a 99% confidence level, the critical value can be obtained from the t-distribution table or statistical software.

The standard error is calculated as the sample standard deviation divided by the square root of the sample size.

Once we have the critical value and the standard error, we can calculate the confidence interval by adding and subtracting the product of the critical value and the standard error from the sample mean.

Interpreting the confidence interval means that we are 99% confident that the true average lifetime falls within the calculated range. In this case, the confidence interval provides a range of values within which we can expect the true average lifetime of individuals suffering from blood cancer to lie with 99% confidence.

No, in the above, case, my friend is incorrect. The value of x is 36. This is solved using the knowledge of arcs.

What is the sum total of arc in a circle?

Because the measure of each arc is the angle formed by that arc at the center of the circle, the total of all arc measurements that comprise that circle is 360 degrees.

Thus,

∡MB = 4x

∡NB = x

∡AM = X

∡AN = 4x (alternate angles)

Based ont he above assertion about arcs,

∡MB + ∡NB +∡AM +∡AN = 360

Hence,

4x + x + x + 4x = 360

Answers

The width of subintervals of f(x) = \(8x^2+3\) with x-axis over the interval [0,2] is (2/n).

How to calculated width of subintervals?

Width of subintervals (Δx) is part of Riemann Sum formula which is represent the interval value of rectangle. For example in attached image, the interval value of first rectangle is 1 (from 0 to 1), the second rectangle is 1 (from 1 to 2), etc.

from x-axis over the interval [0, 2] we get,

a = 0

b = 2

Width of subintervals can be calculated with this formula,

Δx = (b-a)/n

= (2-0)/n

= 2/n

Thus, the width of subinterval is (2/n) for \(8x^2+3\) with x-axis over the interval [0,2].

I solved with substitution since you weren't specific on how to answer it but I got ( 2,3 )

Answer:

x=2

y=3

Step-by-step explanation:

\(\left \{{4x+3y=17{} \atop{5x-2y=4}} \right.\)

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

4x+3y=17,5x−2y=4

To make 4x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 4.

5×4x+5×3y=5×17,4×5x+4(−2)y=4×4

Simplify.

20x+15y=85,20x−8y=16

Subtract 20x−8y=16 from 20x+15y=85 by subtracting like terms on each side of the equal sign.

20x−20x+15y+8y=85−16

Add 20x to −20x. Terms 20x and −20x cancel out, leaving an equation with only one variable that can be solved.

15y+8y=85−16

Add 15y to 8y.

23y=85−16

Add 85 to −16.

23y=69

Divide both sides by 23.

y=3

Substitute 3 for y in 5x−2y=4. Because the resulting equation contains only one variable, you can solve for x directly.

5x−2×3=4

Multiply −2 times 3.

5x−6=4

Add 6 to both sides of the equation.

5x=10

Divide both sides by 5.

x=2

The system is now solved.

In point-slope form, the equation for line that passes through (-3 , -8) and slope -5 is :

y + 5x = -23.

What is equation of line?A straight line's equation is y = mx + c where m is the slope and c is the altitude where the line crosses the y -axis, as well identified as the y -intercept.

Given a line with the coordinates (-3, -8) and a slope of m = -5.

For the line, we must find an equation in point slope form.

(y - y1 ) = m(x - x1) is the point slope form of a line.

According to the question,

(m) slope = - 5

And the line goes through (x1 , y1) = ( -3 , -8 )

Therefore( y - y1 ) = m ( x - x1)

y + 8 = -5 ( x + 3 )

y + 8 = -5x - 15

y + 5x = - 23

Therefore the equation for line in point-slope form is y + 5x = -23.
