A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

"B" is the answer.

I hope this helps!

Arm span is the physical measurement of the length of an individual's arms from fingertip to fingertip. A man’s arm span is appr

Damm [24]

Answer:

The 99th percentile for a man’s arm span is 80.47 inches.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 70, \sigma = 4.5$

99th percentile

X when Z has a pvalue of 0.99. So X when Z = 2.327.

$Z = \frac{X - \mu}{\sigma}$

$2.327 = \frac{X - 70}{4.5}$

$X - 70 = 2.327*4.5$

$X = 80.47$

The 99th percentile for a man’s arm span is 80.47 inches.

From a group of 7 women and 5 men, a committee consisting of 4 women and 3 menis to be formed. How many different committees are

erastovalidia [21]

Answer:

(a) Number of committees formed if there are no restrictions = 350

(b) Number of committees formed if 2 of the women refuse to serve together = 310

Step-by-step explanation:

As per the question,

Number of women = 7

Number of men = 5

The different committees are possible if

(a) There are no restrictions

Number of committees formed

= $^{7}C_{4} \times ^{5}C_{3}$

= 350

(b) 2 of the women refuse to serve together

From the 350, we must subtract the number of ways those two women serve together.

If the men and women both serve together, then 1 woman serve with 4 men.

The men are chosen

$=^{5}C_{3} = 10\ ways$ ,

So

The number we must subtract from the 350 is 4 × 10 = 40

∴ Number of committees formed = 350 - 40 = 310.

PLEASE HELP!!! WILL AWARD BRAINLIEST!!! you work a part-time job earning 6.80/hr with tips that average 2.30/hr you work 20 hr/w

solmaris [256]

143.7 I believe since you take 6.80*20=136+46=2.3*20

136+46=182

182*7.65%=168.08

168.08*8.95%=153.04

153.04*6.1%=143.7

Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are in

dem82 [27]

There is no b unfortunately

Find inverse of x+a

x+a=y

interchAnge

y+a=x
y=x-a

Inverse is

f^{-1}x=x-a

Now

x-a=cx-d
x-cx=a-d
x(1-c)=a-d
x=a-d/1-c

So

You can have any number according to this but

c must not be 1
a and d must not be equal .
All three should belongs to integers set

Note:-

As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
