Answer:

Step-by-step explanation:

$\frac{y}{25}= \frac{32}{100}$

y × 100 = 32 × 25

100y = 800

100y ÷ 100 = 800 ÷ 100

y = 8

Here is a formula for most percentage problems.

Answer:

1. The minimum head breadth that will fit the clientele is of 3.95-in.

2. The maximum head breadth that will fit the clientele is of 9.25-in.

Step-by-step explanation:

Normal Probability Distribution:

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

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 6.6-in and a standard deviation of 1.1-in.

This means that $\mu = 6.6, \sigma = 1.1$

1. What is the minimum head breadth that will fit the clientele?

The 0.8th percentile, which is X when Z has a p-value of 0.008, so X when Z = -2.41.

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

$-2.41 = \frac{X - 6.6}{1.1}$

$X - 6.6 = -2.41*1.1$

$X = 3.95$

The minimum head breadth that will fit the clientele is of 3.95-in.

2. What is the maximum head breadth that will fit the clientele?

The 100 - 0.8 = 99.2nd percentile, which is X when Z has a p-value of 0.992, so X when Z = 2.41.

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

$2.41 = \frac{X - 6.6}{1.1}$

$X - 6.6 = 2.41*1.1$

$X = 9.25$

The maximum head breadth that will fit the clientele is of 9.25-in.

In a class of 80 students ,53 study art ,60 study biology ,36 study art and biology ,34 study art and chemistry ,6 study biology

d1i1m1o1n [39]

Answer:

The missing part is the intersection of all 3, label it x

Now look at the intersection of A and C, it must be 34.

But you already have x accounted for in the intersection of all 3.

So label the part in A and C, but not B as 34-x

36 study A and B, so the part of A and B, but not C is

36-x

Given that 53 study Art, in the A only part we can put

53-(36-x) - (34-x) -x = x - 17

6 study B only, put that in.

So the missing part of B is 60 - 6 - (36-x) - x

= 18

18 study B , but not C, so they could be in A

label the part of A and B, but not C as 18

BUT, we already know that A and B, not C, is 36-x

So 36-x = 18

X=18

I think we are done

A bicycle wheel travels exactly 26/pi inches in I full rotation, what is the area, to the nearst square inch, of a circle the sa

Murrr4er [49]

The area, to the nearst square inch, of a circle the same size az the bicycle wheel is 531 inches².

<h3>What is the area of the circle?</h3>

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

π = pi = 22/7

R = radius

The full rotation of the wheel is equal to the circumference of the wheel.

circumference of the wheel = 2 πr

26π = 2 πr

r = 13 inches

Area = 22/7 x 13³ = 531 inches²
