Answer:

0.57

Step-by-step explanation:

Given that:

food = f ; c = clothes

P(f) = 0.76

P(C) = 0.49

P(fnC) = 0.28

Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?

P(f Given C) = P(f | C)

P(f | c) = p(fnC) / p(C)

P(f | c) = 0.28 / 0.49

P(f | c) = 0.5714

P(f | c) = 0.57

A type of elevator has a maximum weight capacity Y1 , which is normally distributed with mean 5000 pounds and standard deviation
alukav5142 [94]

Answer:

 then value is 0.0228

Step-by-step explanation:

Maximum weight capacity= Y1

Elevator's loaf = Y2

probability that is overloaded :

P(Y2 > Y1)

TakingP( Y2 - Y1) > 0

E[Y1 - Y2 ] = 500 - 4000 = 1000

P( Y2 > Y1) = P( Y2 - Y1 > 0 ) = P( Y1 - Y2 < 0 ) ;

E[Y1 - Y2] = 500-4000 = 1000

P (Y2 > Y1 )

then

P (Y1 - Y2 < 0)

P((Y1-Y2)-1000)/50 = (0-1000/500)

P((Y1 - Y2 )  - 2)

 then value is 0.0228

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20in
Rom4ik [11]

Answer:

100 inches

Step-by-step explanation:

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.

This is calculated using proportion

Side length/Perimeter

Hence:

Side length of smaller triangle = 19 inches

Perimeter of smaller triangle = 95 inchee

Side length of larger triangle = 20 inches

Perimeter of larger triangle = x

19/95 = 20/x

Cross Multiply

19x = 95 × 20

x = 95 × 20/19

x = 100 inches

The perimeter of the larger triangle = 100 inches

Given the equation :

S=2000n+55000

Comparing the equation given to the standard linear equation formula :

y = mx + c

Where ; c = intercept ; m = slope ; y = dependent variable and x = independent variable

From The comparison, the slope of the equation given = 2000.

According to the context, the slope means that Camden salary will increase by 2000 each year.
