Answer:

the son is 76.5 inches

Step-by-step explanation:

We know that the predicted height of the son based on the father's height is given by the equation ŷ = -2.8 + 1.1x, where x is the height of the father. We are also given that the residual for the son's height of one father who is 70 inches tall is 2.5.

The residual is the difference between the actual value of y and the predicted value of y. So we can set up the equation:

y - ŷ = residual

where y is the actual height of the son.

Substituting the given values, we get:

y - (-2.8 + 1.1(70)) = 2.5

Simplifying, we get:

y - 74 = 2.5

y = 76.5

Therefore, the actual height of the son is 76.5 inches.

Answer:

I'(-1, 3)

Step-by-step explanation:

Since you are moving the point 3 units left, you subtract 3 from the x-value, which is what is changing from that translation. Since you are moving 6 units up, you add 3 to the y-value, which is what is changing from that translation. Any horizontal translation will change the x-value and any vertical translation will change the y-value.

Answer:

The last year value of the house will be $230,000.

Step-by-step explanation:

GIVEN: Decrease in house price = 20%

            Current house price = $184,000

TO FIND: Value of the house last year

SOLUTION:

If the value of the house decreased by 20% during last year, this means the value of the house this year is 80% of last year's value.

Let the value of the house last year be 'x'.

If the value of the house today is  $184,000, then:

                           \(80/100 * x = 184,000\\\\0.8x = 184,000\\\\x = 184,000/0.8\\\\x = 230,000\)

Therefore, the last year value of the house will be $230,000.

If the data from X2 is higher than the data from X1, then the researcher can conclude that using an octane booster increases gasoline mileage

X1: Gas mileage before using octane booster

X2: Gas mileage after using octane booster

The researcher is comparing X1 and X2, to determine if using an octane booster increases gasoline mileage.

1. The researcher selected a random sample of seven cars and drove them for two weeks without using the octane booster (X1).

2. The researcher then drove the same seven cars for two weeks with the octane booster (X2).

3. The researcher then compared the data from X1 and X2 to see if there was an increase in gasoline mileage.

4. If the data from X2 is higher than the data from X1, then the researcher can conclude that using an octane booster increases gasoline mileage.

Answer:

-(2/3)x+4

Step-by-step explanation:

For the slope you do rise over run, since the graph intercepts the y-axis at 4 and goes down to 0 the rise is -4 and from the same point the graph "runs" 6 the rise/run is -4/6 which can be simplified to -2/3. For the y-intercept you simply find where the graph touches the y-intercept and add (or subtract if the number is negative) that to the end of the equation.

The new coordinates of C' are (3', -4)

The statement is given as:

Point C (3, -4) is reflected over the y-axis.

The rule of reflection over the y-axis is

(x, y) = (-x, y)

So, we have:

Point C = (3, -4)

This means that:

Point C' = (3', -4)

Hence, the new coordinates of C' are (3', -4)

The correct answer is option 3: 2250. To calculate the number of different clients that can be identified with a coding system we need to multiply the number of options for each component.

For the two-letter component, there are five options (A, D, R, S, U) that can be chosen for each letter. Since repetition is allowed, there are 5 choices for the first letter and 5 choices for the second letter. Therefore, there are 5 x 5 = 25 possible combinations of two letters.

For the two-digit component, there are 10 options (0-9) for the first digit. Since no digit can be repeated, there are 9 options for the second digit (one less than the available options). Therefore, there are 10 x 9 = 90 possible combinations of two digits.

To calculate the total number of different clients that can be identified, we multiply the number of options for the two-letter component (25) by the number of options for the two-digit component (90). This gives us a total of 25 x 90 = 2250 different clients that can be identified with the coding system.

#A company uses a coding system to identify its clients. Each code is made up of two letters and a sequence of digits, for example AD108 or RR45789 The letters are chosen from A;D; R; S and U.

The length of the rectangular  playground is 241.86 foot.

Given that area of rectangle is 19,500 sq.ft and length of rectangle is three times its width.The area for rectangle is given by formula: A=LW.

Now according to the given condition, L= 3W. Further we'll solve by putting L= 3W in the formula for rectangle.

A=LW

As given A= 19,500 sq.ft and considering L=3W,

19,500 = 3W*W

19,500 = 3W^2

∴ W^2 = 6500

∴ W = \(\sqrt{6500}\)

∴ W = 80.6225 ft. ≈ 80.62 ft.

Now putting the value W = 80.62 in equation L =3W,

L = 3* 80.62

L = 241.86 ft.

The length of the rectangular playground is 241.86 foot.

Answer:

Step-by-step explanation:

In a right-skewed distribution, the correct answer is: a. The mean tends to be greater than the median.

In a right-skewed distribution, the tail of the distribution is longer on the right side, indicating that there are a few extreme values that pull the overall distribution towards the right. As a result, the mean is typically influenced by these extreme values and tends to be greater than the median.

The median represents the middle value in a distribution when the data points are arranged in order. Since the right-skewed distribution has a longer tail on the right side, the median is less affected by the extreme values and tends to be closer to the values in the bulk of the distribution.

Therefore, option a is the correct answer: In a right-skewed distribution, the mean tends to be greater than the median.

Answer:

Since the decoration is in the shape of a triangle, we can use the formula for the area of a triangle to solve for its height. The area of a triangle is given by:

Area = (1/2) x base x height

Let's call the height of the decoration h. We know that the base after firing is 9 inches, so we can plug in the given values and solve for h:

Area = (1/2) x 9 x h

Area = 4.5h

We don't know the exact area of the decoration, but we do know that the decoration maintains its shape after firing. This means that the ratio of the areas before and after firing is the same, and so is the ratio of the heights and bases. Since the height and base are proportional, we can write:

h / 15 = 9 / 10

Simplifying the equation, we get:

h = (9/10) x 15

h = 13.5

Therefore, the height of the finished decoration is 13.5 inches.

To solve the expression -25 x (84/21) + (-3) x (-6), follow these steps:

Step 1: Perform the division inside the parentheses.
(84/21) = 4

Step 2: Replace the terms and rewrite the expression.
-25 x (4) + (-3) x (-6)

Step 3: Perform the multiplications.
-25 x 4 = -100
-3 x -6 = 18

Step 4: Rewrite the expression and perform the addition.
-100 + 18

Step 5: Calculate the final result.
-100 + 18 = -82

The length of the tangent x is 11.2 units.

Given is circle with radius 8.4 units and a tangent with x units, we need to find the length of the tangent,

Since we know that the tangents are perpendicular to the circle, so to find the length,

Using Pythagoras theorem,

Hypotenuse is 5.6+8.4 = 14 units,

So,

14² = 8.4² + x²

x = √196 - 70.56

x = 11.2
