∠STR + 60° + 58° = 180°

∠STR = 62°

∠PRQ = 62°

Answer:

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

F(x)    0.17    0.04    0.65    0.91      1      

Step-by-step explanation:  

Given that;

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

cumulative distribution function can be calculated by;  be cumulatively up the value of p(x) with the values before it;

so

x      F(x)

0     P(X = 0) = 0.17

1       P(X = 0) + P(X = 1) = 0.17 + 0.23 = 0.4

2      P(X = 0) + P(X = 1) + P(X = 2) = 0.17 + 0.23 + 0.27 = 0.65

3      P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.17 + 0.23 + 0.27 + 0.24 = 0.91

4      P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.17 + 0.23 + 0.27 + 0.24 + 0.09 = 1

Therefore, cumulative distribution function f(x) is;

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

F(x)    0.17    0.04    0.65    0.91      1      

Answer: 10/20 or 1/2

Step-by-step explanation:

10 is the half of twenty, if she’s gonna eat the rest, she’s gonna eat the other half

Santa ate 10/20. right?

so you would subtract 10 from 20

which would give you 10

so Mrs. Claus also ate 10/20

-----

Another way to solve:

since 10/20 = 50%

Mrs. Claus ate the same amount

because 50% is half of 100% ( 1 whole )

So, Mrs. Claus ate 10/20

Answer:

125q^6p^3

Step-by-step explanation:

Answer:

We have strong evidence that on average, students study less than 150 minutes per night during the school week

Step-by-step explanation:

Normal distribution:

mean     μ₀ = 150

Sample:

Sample size    n = 272

Sample mean   x = 141

Sample standard deviation  s  = 66

The standard error of the sample mean  SE = σ /√n

SE = 66/√272

SE = 66 / 16,49

SE = 4

Test Hypothesis:

Null hypothesis                            H₀             x  =   μ₀

Alternative hypothesis                Hₐ            x <    μ₀

z(s)  test statistics is:

z(s)  =  ( x  -  μ₀ ) / s/√n

z(s) = - 9 /4

z(s) =  -  2,25

p-value  for that z(s)      p-value  = 0,0122

Then for α =  0,05 p-value < 0,05

We are in the rejection region we need to reject H₀

Answer:

The slope is a positive linear slope

The slope is 2

The y-intercept is -4

The equation of this line would be: y = 2x - 4

Step-by-step explanation:

y = mx + b format

m = slope

b = y-intercept

and x and y are the x and y components

Answer:

25/64

Step-by-step explanation:

do what's inside parentheses first

-3/8 - 2/8 = -5/8

-5/8(-5/8) = 25/64

Answer:

base = 19.1 km

Step-by-step explanation:

start with formula:

A = bh/2

plug in what's known:

114.6 = 12b/2

114.6 = 6b

b = 114.6/6

b = 19.1

Answer:

The change in temperature was of -16ºF, that is, a decrease of 16ºF.

Step-by-step explanation:

At noon, the temperature was of 82°F.

By midnight the temperature had fallen to 66°F.

Change:

Final value subtracted by initial value, so

66ºF - 82ºF = -16ºF

The change in temperature was of -16ºF, that is, a decrease of 16ºF.

197.92

Step-by-step explanation:

3.14*3*2*7=197.92

Answer:

197.92 cu cm  to the nearest hundredth

Step-by-step explanation:

Volume = area of the base time the height.

Your base is a circle, so A = [tex]\pi r^{2}[/tex] = [tex]\pi 3^{2}[/tex] = 9π

Vol = 9π(7) = 63π ≅ 197.92 cu cm  to the nearest hundredth

Answer:

187 Books

Step-by-step explanation:

First you need to figure out the area of the closet. To do this you need to do 20 x 25 x 30 which equals 15,000. Then you should figure out the area of the books. To do this you would do 8 x 5 x 2 which equals 80. Then do 15,000 divided by 80 and you get 187.5 but you cant fit half a book in so then you round down and you get 187.
