Ms. Sanchez drove 19 1/2 miles 2/3 hour. What was her speed in miles per hour

Answers

Answer:

hi

hi hi hi hi hi h hi hi hi hi hi hi hi

Step-by-step explanation:

Answer:

29.25 / 29 1/4 MPH (Miles Per Hour)

Step-by-step explanation:

2/3 of an hour equals 40 minutes, so 19 1/2 miles is 40 minutes. 20 minutes is 1/3 of an hour, which is the missing amount of 2/3. Divide 19 1/2 miles by 2 to get 9 3/4 miles (which is how far Ms. Sanchez can go in 20 minutes). multiply by 3 to get 29 1/4 Miles Per Hour.

What does it mean to say that a data point has a residual of 0?
A. The point lies above the regression line.
B. The point lies directly on the regression line.

D. The point falls at the origin.

Answers

Hi!!!

B. the point lies directly on the regression line.

Hope this helped!

Have a good day:)

The point lies directly on the regression line.

Option B is the correct answer.

What is a regression line?

A regression line is a straight line that represents the relationship between two variables in a scatter plot.

In other words, it is a line that best fits the data points in a scatter plot by minimizing the difference between the actual data points and the predicted values on the line.

We have,

When we talk about the residual of a data point in the context of regression analysis, we are referring to the difference between the actual value of the response variable (dependent variable) for that data point and the predicted value of the response variable based on the regression equation.

If a data point has a residual of 0, it means that the predicted value for that data point is exactly equal to the actual value of the response variable.

This can occur when the data point falls directly on the regression line, as in option B.

Thus,

The point lies directly on the regression line.

Please help i don’t know if I’m doing this right

Answers

Answer:

x = 41

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + 40^2 = c^2

81 + 1600 = c^2

c^2 = 1681

c = 41

Step-by-step explanation:

In order to find the hypotenuse of a right triangle, you must remember the theorem:

a² + b² = c².

40 to the second power is 1600, and 9 to the second power is 81.

Add these together for a total of 1681, but you're not done yet. We need to find what multiplied by itself equals 1681, since c is to the second power.

The square root is 41, so x is 41.

Answer:

XZ > XY > YZ

Step-by-step explanation:

1. Approach

To solve this problem, one must find the value of (x), then the measure of every angle in the triangle. Remember, the sum of all angles in a triangle is equal to 180 degrees. Another property of a triangle is that the largest side of a triangle will be opposite the largest angle of the triangle, conversely, the smallest side of a triangle will be opposite the smallest angle in the triangle.

2. Find the value of (x)

The sum of all angles in a triangle is equal to 180 degrees. Using this theorem, one can state,

m<X + m<Y + m<Z = 180

Substitute,

(50) + (5x + 10) + (5x) = 180

Simplify,

10x + 60 = 180

Inverse operations,

10x + 60 = 180

       -60     -60

10x = 120

/10    /10

x = 12

3. Find the measure of each angle

Now substitute the value of (x) into the expressions given to represent the value of each angle.

m<X = 50

m<Y = 5x + 10 = 5(12) + 10 = 60 + 10 = 70

m<Z = 5x = 5(12) = 60

4. Now apply this to find the comparative lengths of the sides

One property of a triangle is that the side opposite the largest angle in the triangle is the largest side. Moreover, the side opposite the smallest angle in a triangle is the smallest side. In this problem, it is impossible to find the exact lengths of the sides of the triangle, but one can find out which side is larger or smaller than the other side.

m<Y = 70

m<Z = 60

m< X = 50

m<Y > m<Z > m<X

Side XZ is opposite m<Y

Side XY is opposite m<Z

Side YZ is opposite m<X

This means,

XZ > XY > YZ

PLEASE HELP! The AHS football team did a weigh-in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. What percentage of players are under 86kg?

Answers

Answer:  2.5%

=============================================================

Explanation:

Notice how 98-2*6 = 98-12 = 86. So we're 2 standard deviations below the mean.

Start at the center, which is where the highest point is located. The value 98 is at the center. Then move 2 spots to the left, which has us move 2 standard deviations lower than the mean, and we arrive at 86. Refer to the diagram below.

From here, we add up the percentages in that diagram that are below the 86 mark. Those percentages are the 0.15% and 2.35%

So we get (0.15%) + (2.35%) = 2.5% which is the answer

Side note: This diagram is using the Empirical Rule. Some textbooks call it the "68-95-99.7 rule", but that's more clunky of a name in my opinion. The three values 68, 95 and 99.7 refer to the approximate percentage values within 1, 2 and 3 standard deviations of the mean.

Annabelle invested $5,900 in an account paying an interest rate of 2% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $7,440?

Answers

Answer:

Step-by-step explanation:

Continuous compounding has the form

[tex]A=Pe^{rt}\\ \\ t=\frac{ln\frac{A}{P}}{r}\\ \\ t=\frac{ln\frac{7440}{5900}}{0.02}\\ \\ t\approx 11.6\\ \\ t=12[/tex]

Therefore it will take 12 years for the value of the account to reach $7,440.

What is Compound Interest ?

Compound interest (or compounding interest) is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

Annabelle invested amount $5900

Final Amount $7440

Rate = 2% compounded continuously

When compounded Continuously ,

[tex]\rm A = P e^{rt}\\\\\\t=\dfrac{ln \frac{A}{P}}{r}\\\\\\\\t=\dfrac{ln \frac{7440}{5900}}{0.02}\\\\t= 12[/tex]

it will take 12 years for the value of the account to reach $7,440.
