Answer:

Area= L*W= 13*7 = 91ft^2

Step-by-step explanation:

L= 6+W

Perimeter of the rectangle=2(L+W)=40

2(6+W+W)=40

2(6+2W)=40

12+4W=40

4W=40-12

4W=28

W=28/4

W=7ft

L=6+7=13ft

Area=L*W=13*7=91ft^2

A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a 50-50 chance of

Verizon [17]

Answer:

$Probability = 0.50$

Step-by-step explanation:

Given

$Probability = 50\ 50\ chance$

$Successful\ Bids = 80\%$

$Unsuccessful\ Bids = 35\%$

Required

Determine the probability before the request of past experience

In this case, we only consider the 50 50 chance probability

$Probability = \frac{50}{50 + 50}$

$Probability = \frac{50}{100}$

$Probability = 0.50$

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). Heavier cars tend to

Maksim231197 [3]

Answer:

Correct option: A. Weight.

Step-by-step explanation:

In regression analysis there are two kinds of variables: Explanatory and Response variable.

The explanatory variable are used to predict the changes in the response variable. They are also known as independent or predictor variable.

The response variable are observed for any changes caused by the explanatory variable. They are also known as the dependent or experimental variable.

In this case it is provided that heavier cars have lower fuel efficiencies.

It implies that there is linear inverse relationship between the variables weight of the car and fuel efficiency.

The response variable is the fuel efficiency and the explanatory variable is the weight of the car. Since the weight of the car is used to determine the fuel efficiency.

Thus, the explanatory variable is the weight of the car.

A satellite dish has cross-sections shaped like parabolas. The receiver is located 13 inches from the base along the axis of sym

horsena [70]

Answer:

Depth = 3.3 inches

Step-by-step explanation:

Given that the shape of the satellite looks like a parabola

The equation of parabola is given as follows

$x^2=4\times a\times y$

Where

a= 13

Therefore

$x^2=4\times 13\times y$

$x^2=52\times y$

Lets take (13 , y) is a

Now by putting the values in the above equation we get

$13^2=52\times y$

$y=\dfrac{13^2}{52}=3.25$

y=3.25 in

Therefore the depth of the satellite at the nearest integer will be 3.3 inches.

Depth = 3.3 inches

Answer:

y = 1/2x + 6

Step-by-step explanation:

The slope m is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (10 -6)/(8 -0) = 4/8 = 1/2

The y-intercept is given by the formula ...

b = y -mx

b = 6 -(1/2)(0) = 6

Then the slope-intercept equation is ...

y = mx +b

y = 1/2x +6
