Answer: The restaurant can make 199 pancakes in two hours.

Step-by-step explanation:

Given: Total number of cups of pancake mix used in 1 hour = 124

Mix required for each pancake = [tex]1\dfrac14=\dfrac{5}{4}[/tex]

Number of cups of pancake mix used in 2 hours = 2 x 124 = 248

Number of pancakes made = (Number of cups of pancake mix used in 2 hours ) ÷ (Mix required for each pancake )

[tex]=248\div\dfrac54\\\\=248\times\dfrac45\\\\= 198.4\approx199[/tex]

Hence, the restaurant can make 199 pancakes in two hours.

Answer:

149.8 feet

Step-by-step explanation:

θ = Angle of elevation = 33°

The length of string Jaden lets out = Hypotenuse = 275 feet.

How high above the ground that the kite is flying = Opposite Side.

We are solving this question using the Trigonometric function of Sine

Sin θ = Opposite Side/Hypotenuse

Sin 33 = Opposite/275 feet

Cross Multiply

Sin 33 × 275 feet = Opposite

Opposite side(Height ) = 149.77573463 feet

Approximately to the nearest tenth = 149.8 feet

The dilation is solved and the scale factor of line is A'B' = 3AB

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the scale factor of the dilation be represented as k

Now , the scale factor k = 3

So , the ratio of the corresponding sides is given by

A'B' / AB = 3

Multiply by AB on both sides , we get

A'B' = 3AB

Hence , the dilation is simplified as A'B' = 3AB

Answer:

Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)

Step-by-step explanation:

Here, we want to calculate the elevation relative to sea level

The sea level refer to the base of the sea

We follow the flight procedure;

distance of 24 1/2 ft above sea level , then go further up by 5

its elevation now is 24 1/2 + 5 = 29 1/2 ft

A change of -47 2/3 ft

So the elevation now will be;

29 1/2 - 47 2/3

= 59/2 - 143/3

= (177-286)/6 = -109/6

= -18 1/6 ft

Given:

The regression equation for change in temperature, y, to amount of rain, r, is given by

[tex]\hat{y}=0.2-1.4r[/tex]

The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

To find:

The residual and interpret it.

Solution:

According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

So, the actual value is 2.3 degrees.

Put r=0.4 in the given equation, to find the predicted value.

[tex]\hat{y}=0.2-1.4(0.4)[/tex]

[tex]\hat{y}=0.2-0.56[/tex]

[tex]\hat{y}=-0.36[/tex]

We know that,

Residual = Actual value - Predicted value

[tex]Residual=2.3-(-0.36)[/tex]

[tex]Residual=2.3+0.36[/tex]

[tex]Residual=2.66[/tex]

Residual is positive because predicated value is less than the actual value.

So, the regression line underpredicts the temperature change.

Therefore, the correct option is B.

Step-by-step explanation:

Answer:

$5.50

Step-by-step explanation:

1.) The first step is finding what 45% of $10 is. We can do this by turning 45% into a decimal number (45%=0.45). We then multiply 0.45 by the $10.

2.) 0.45×$10=$4.50 ; We just found that 45% of $10 is $4.50

3.) Because the shirt is 45% less than the original price (45% off), we need to subtract the 45% (which is equal to $4.50) from the original price, $10

4.) $10-$4.50=$5.50, the new price

To have only one solution the two lines must have different slopes, then the correct option is:

y = x + 4.

We want our system to have exactly one solution, so the two lines must have different slopes.

The already graphed line s:

y = 2x + 4

Notice that the slope is 2, then we need to select the option with an slope different than 2, which is the last option:

y = x + 4

If we graph that line, the system will have only one solution.
