Answer:

119-50 pounds = 69 so 169 pounds -step explanation: blood= weight (k)

Step-by-step explanation:

y=kx

2

4.6 = 170k

finding the constant of variation

3

k= 0.02875

4

equation relates quarts of blood to weight

5

RESULT

4.6 = 170k

y= 0.02875x

y= 0.02875(175)= 5.03125

Answer:

Ww=84 lb

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y=k.x

Where k is the constant of proportionality.

The value of k is obtained by using the values of a specific point.

The weight of water Ww in a person's body varies directly as their body weight Wb as follows:

Ww=k.Wb

We are given a 170-lb person contains 119 lb of water. Substituting:

119=k.170

Solving for k:

k=119/170=0.7

The function is:

[tex]Ww=0.7\cdot Wb[/tex]

To find how much water is in the body of a 120-lb person, we substitute Wb=120:

[tex]Ww=0.7\cdot 120[/tex]

Ww=84 lb

Step-by-step explanation:

Answer:

0.2172<x<0.2668

Step-by-step explanation:

The formula for calculating the confidence interval is expressed as;

CI = xbar ± (z*s/√n)

xbar is the average = 0.242ppm

z is the z score at 95% confidence = 1.96.

s is the standard deviation = 0.04pm

n is the sample size = 10

substitute the values into the formula;

CI = xbar ± (z*s/√n)

CI = 0.242 ± (1.96*0.04/√10)

CI = 0.242 ± (1.96*(0.04/3.1623))

CI = 0.242 ± (1.96*(0.01265))

CI = 0.242 ± (0.02479)

CI = (0.242-0.02479, 0.242+0.02479)

CI = (0.2172, 0.2668)

Hence a 95% confidence interval for the mean mercury content of coal from this source is 0.2172<x<0.2668.

Answer:

The sum of interior angles of given polygon is 900°

Step-by-step explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

[tex]Sum\ of\ interior\ angles = (n-2)*180[/tex]

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

[tex]Sum = (7-2)*180 = 5*180 = 900[/tex]

Hence,

The sum of interior angles of given polygon is 900°

Answer:

[tex]P(X = 0) = 0.1296 [/tex]

Step-by-step explanation:

This can be solved using the binomial distribution because the cars arriving at the stop are independent of each other. This means we will use:

[tex]P(X = x) = \binom{n}{x} p^{x} q^{n - x}[/tex]

Where p is the probability of success, q = 1 - p is the probability of failure and n is the number of cars sampled.

p = 0.4

q = 0.6

n = 4

Therefore,

[tex]P(X = 0) = \binom{4}{0} 0.4^{0} 0.6^{4}[/tex]

This is equal to

[tex]P(X = 0) = 1 \times 1 \times 0.1296 [/tex]

[tex]P(X = 0) = 0.1296 [/tex]

Answer:

  G  45

Step-by-step explanation:

If Z is the circumcenter, it is equidistant from the vertices T, U, V. That is, ΔZUV is an isosceles triangle and Y is the midpoint of UV.

If Y is the midpoint of UV, then UY = VY = 22.5, and UV = UY +VY = 45.

The length of UV is 45.

Answer:

$5673.36

Step-by-step explanation:

4 weeks in a month

12 months in a year

Therefore, they get paid twice in a month.

236.39 * 2(twice in a month) = 472.78 per month

Take this and times it by 12 since there are 12 months in a year.

472.78*12 = 5673.36

Answer:

The probability of a pill having more than 24.125 mg active substance is 0.0495.

Step-by-step explanation:

Let X denote the amount of active substance in each pill.

It is provided that,[tex]X\sim N(20,\ 2.5^{2})[/tex]

Compute the probability of a pill having more than 24.125 mg active substance as follows:

[tex]P(X>24.125)=P(\frac{X-\mu}{\sigma}>\frac{24.125-20}{2.5})[/tex]

                       [tex]=P(Z>1.65)\\\\=1-P(Z<1.65)\\\\=1-0.95053\\\\=0.04947\\\\\approx 0.0495[/tex]

Thus, the probability of a pill having more than 24.125 mg active substance is 0.0495.
