Answer:

x^2+7x +49/4 and (x+7/2)^2

x^2+bx +b²/4 and  (x+b/2)^2

Step-by-step explanation:

Given the expression

x^2+7x+c

We need to find the constant that completes the expression

Take the half of the cpeffiecient of x = 7/2

Taking the square of the result

Square of the result  = (7/2)^2

Hence c = (7/2)^2

The expression becomes;

x^2 + 7x + (7/2)^2

= x^2+7x +49/4

= (x+7/2)^2

For x^2+bx+d

We need to find the constant that completes the expression

Take the half of the cpeffiecient of x = b/2

Taking the square of the result

Square of the result  = (b/2)^2

Hence d = (b/2)^2

The expression becomes;

x^2 + bx + (b/2)^2

= x^2+bx +b²/4

= (x+b/2)^2

Answer:

285 square units

Step-by-step explanation:

A=π⅓(6V)⅔

Here Volume is 144π

So,

A= π⅓ (6(144π))⅔

=π⅓ (6(452.4)⅔

=π⅓ (2714.4)⅔

=π⅓ (194.5)

=(3.14)⅓ (194.6)

=(1.46) (194.6)

=284.9

=285

20-13=7

so i think the answer would be m 13-20?

Answer:

205.75

Step-by-step explanation:

first, separate the floor into 3 different rectangles to calculate the area and then add them together.

area of rec=L*B

rec 1: 11.5*8=92

rec 2: (12.5-5)*(18.5-8-7)=26.25

rec 3:7*12.5=87.5

Then:

92+26.25+87.5=205.75

Answer:

b) 55.99%

c) 0.25%

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 54.3 pounds and a standard deviation of 14.5 pounds.

This means that [tex]\mu = 54.3, \sigma = 14.5[/tex]

1. What percentage of Americans' annual salad and cooking oil consumption is less than 10 pounds?

The proportion is the pvalue of Z when X = 10. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{10 - 54.3}{14.5}[/tex]

[tex]Z = -3.06[/tex]

[tex]Z = -3.06[/tex] has a pvalue of 0.0011

0.0011*100% = 0.11%.

2. What percentage of Americans' annual salad and cooking oil consumption is between 35 and 60?

The proportion is the value of Z when X = 60 subtracted by the pvalue of Z when X = 35.

X = 60

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{60 - 54.3}{14.5}[/tex]

[tex]Z = 0.39[/tex]

[tex]Z = 0.39[/tex] has a pvalue of 0.6517

X = 35

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{35 - 54.3}{14.5}[/tex]

[tex]Z = -1.33[/tex]

[tex]Z = -1.33[/tex] has a pvalue of 0.0918

0.6517 - 0.0918 = 0.5599

0.5599*100% = 55.99%

3. What percentage of Americans' annual salad and cooking oil consumption is more than 95 pounds?

The proportion is 1 subtracted by the pvalue of Z when X = 95.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{95 - 54.3}{14.5}[/tex]

[tex]Z = 2.81[/tex]

[tex]Z = 2.81[/tex] has a pvalue of 0.9975

1 - 0.9975 = 0.0025

0.0025*100% = 0.25%

(1.) 0.11% of Americans annual salad and cooking oil consumption is less than 10 pounds.

(2) 55.99% of Americans annual salad and cooking oil consumption is between 35 and 60.

(3).0.25% Americans annual salad and cooking oil consumption is more than 95 pounds.

Given, the average american consumed 54.3 pounds of salad and cooking oils in 2008.

the mean of salad and cooking oil consumption is approximately 54.3 pounds and a standard deviation of 14.5 pounds.

The formula for calculating a z-score is,

[tex]z = \dfrac{(X-\mu)}{\sigma}[/tex]

where [tex]X[/tex] is the raw score, μ is the population mean, and σ is the population standard deviation.

The value of the z-score tells you how many standard deviations you are away from the mean. If a z-score is equal to 0, it is on the mean. A positive z-score indicates the raw score is higher than the mean average.

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

1. percentage of Americans annual salad and cooking oil consumption is less than 10 pounds.

Here X=10

[tex]z=\dfrac{10-54.3}{14.5}[/tex]

[tex]z=-3.06[/tex]

Since [tex]z=-3.06[/tex] has a p value of 0.0011,so

[tex]0.0011\times100\%=0.11\%[/tex]

2.percentage of Americans' annual salad and cooking oil consumption is between 35 and 60.

the proportion is the value of Z when X = 60 subtracted by the p value of Z when X = 35.

At X=60,

[tex]z=\dfrac{60-54.3}{14.5}[/tex]

[tex]z=0.39[/tex]

0.39 has a p value of 0.6517.

At X=60,

[tex]z=\dfrac{35-54.3}{14.5} \\[/tex]

[tex]z=-1.33[/tex]

-1.33 has a p value of 0.0918.

Now,[tex]0.6517 - 0.0918 = 0.5599[/tex]  

[tex]0.5599\times100\% = 55.99\%[/tex]

3. percentage of Americans' annual salad and cooking oil consumption is more than 95 pounds.

Here, The proportion is 1 subtracted by the p value of Z when X = 95.

[tex]z=\dfrac{95-54.3}{14.5}[/tex]

[tex]z=2.81[/tex]

[tex]z=2.81[/tex] has a p value of 0.9975.

So, [tex]1 - 0.9975 = 0.0025[/tex].

Now, [tex]0.0025\times100\% = 0.25\%[/tex].

Hence the correct percentage is 0.11%,55.99% and 0.25% respectively.

Answer:

angle bisector

Step-by-step explanation:

In the picture shown in the question, the line segment SQ would be considered the angle bisector. This is because it is dividing the interior angles' opposite side into two line segments. Hence the line segments PQ and QR. The angle bisector divides the opposite side into line segments that are proportional to the other two sides of the triangle which in this case can be seen by the top left indication in the picture stating that PQ and QR are the same.

1130.4

Step-by-step explanation:

The volume of a cylinder is πr^2h, where r is the radius and h is the height.

We are given the height, 10m.

The diameter is 2m more than the height, so 2+10=12m.

The radius is half the diameter, so 12m/2=6m.

Use r=6 and h=10 in the formula to get the volume

π6^2*10≈1130.4
