The answer is D because a simple way to find the midpoint is to find the average of the coordinates by adding up the x values and dividing by two and the same for the y values. So for x it is -4 + 1 which is -3 and that divided by two is -1.5 and same with the y coordinate.

Using the equation y = 2x – 3, what would the input need to be for an output of 7?

Answers

Answer:

Step-by-step explanation:

We have an equation and are asked to find the input of x when y = 7.

The output = y = 7

The input = x

7 = 2x - 3

2x - 3 = 7

We need to find a number that multiplied by 2 which then is subtracted by 3 equals 7. We can use the backwards method to solve our answer.

2x - 3 = 7

7 + 3 = 2x

10 = 2x

Solve for x by dividing 2 from both sides :

x = 5.

Therefore, you would need an input of 5 to get 7 as the output.

Proof :

2(5) - 3 = 7

10 - 3 = 7

Answer:

x = 5

Step-by-step explanation:

Remark

This is a fancy way of asking you what is the value of x when y = 7

Equation

7 = 2x - 3

Solution

7 = 2x - 3 Add 3 to both sides

7 + 3 = 2x Combine the left.

10 = 2x Divide by 2

2x/2 = 10/2

x = 5

The yearbook club had a meeting. The meeting had 18 people, which is one-third of the club. How many people are in the club?

Answers

Answer:

Step-by-step explanation:

Number of people in the meeting= 18

Out of this number 1/3 are from the club

Therefore the total number of club members can be calculated as follows

= 1/3 × x= 18

x = 18 × 3

= 54

Hence the number of people in the club is 54

At 186282 miles per second, how far does light travel in a year? Give your answer in miles, but use scientific notation, which expresses a number like 93400000 as 9.34 × 107 (which might appear on your calculator as 9.34 E7 instead). A year is approximately 365.25 days. pleaasseeeeee heeelelpepepel,

Answers

Answer:

Use dimensional analysis to answer each of the following questions. To find the distance light travels in a year for part a, convert sec to yr by using unit ratios with min, hr, and days in their denominators. Thus, a light year is approximately 5,874,589,152,000 mi

The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.

What is speed?

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

At 186282 miles per second.

We know that in one light year, the number of seconds will be 31.536 × 10⁶.

Then the distance is given as,

186282 = d / (31.536 × 10⁶)

d = 31.536 × 10⁶ × 186282

d = 5.89 × 10¹² miles

The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.

The shaded "O" on "2" implies that 2 is included, therefore, x is either equal to 2 or less than 2 (x ≤ 2) since the line is towards our left side. This, we would have:

A gambler claims that horses in a horse race that start closer to the rail have an advantage over horses that start further from the rail because the horses closer to the rail have a shorter distance to travel to win the race. In a sample of 120 races, the following data show the number of winners from each starting position. If the starting position is not a factor then each starting position should have produced 20 winners.
Starting position: 1 2 3 4 5 6
# of Winners: 25 22 18 19 21 15
Test the hypothesis at the 5% level of significance to see if starting position is a factor.

Answer:

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races

Step-by-step explanation:

Given the data in the question;

Starting position: 1 2 3 4 5 6

# of Winners: 25 22 18 19 21 15

Mean x" (E) = (25+22+18+19+21+15)/6 = 120/6 = 20

Observed/Expected value table;

O E ((O-E)²) / E

22 20 0.2

18 20 0.2

19 20 0.05

21 20 0.05

15 20 1.25

∑ 3

so using chi square = ∑(((O-E)²) / E) = 3

DF = n-1 = 6-1 = 5

then, the critical chi square value is;

significance level = 0.05

chi square( critical ) = 11.07049769

from table;

p - value = 0.699986

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races

If money is invested for a short period of time, simple interest is paid using the following formula.

I = Prt

P is the money invested, or principal amount, r is the simple interest rate, and t is the time, in years, the money is invested.

Given P = $2,000, t = 2 years, and I = $280, what is the simple interest rate?

A. 7%

B. 0.7%

C. 8%

D. 0.07%

Answers

Answer:

A. 7%

Step-by-step explanation:

Given the following data;

Principal, P = $2,000

Time, T = 2 years

Simple Interest, I = $280

To find the simple interest rate, R?

Mathematically, simple interest is calculated using this formula;

[tex] S.I = \frac {PRT}{100} [/tex]

Where;

S.I is simple interest. P is the principal. R is the interest rate. T is the time.

Substituting into the equation, we have;

[tex] 280 = \frac {2000*R*2}{100} [/tex]

Cross-multiplying, we have;

[tex] 280 * 100 = 4000*R[/tex]

[tex] 28000 = 4000R [/tex]

[tex] R = \frac {28000}{4000} [/tex]

Simple interest rate, R = 7%

A diver is on a diving board 12 meters above the water. He dives vertically from the board with initial velocity of 4.9 meter/sec. how high will the diver get above the water?

Answers

Answer:

13.225 m

Step-by-step explanation:

Given that :

Initial Velocity, u = 4.9m/s

Acceleration due to gravity, a = - 9.8 m/s² (downward)

Distance, S = - 12

According to the motion equation :

S = ut + 0.5at²

S = 4.9t + 0.5(-9.8)t²

S = 4.9t - 4.9t² - - - (1)

At the highest point, v = 0

v² = u + at

0 = 4.9 + - 9.8t

-9.8t = - 4.9

t = 4.9/9.8

t = 0.5s

Put t = 0.5 in (1) above

S = 4.9(0.5) - 4.9(0.5)²

S = 2.45 - 1.225

S = 1.225 m

Total height :

(12 + 1.225) m = 13.225 m

y = 4x+4

Step-by-step explanation:

Using the coordinate point (1, 8) and (2, 12) from the table

Slope m = 12-8/2-1

m = 4/1

m = 4

Get the intercept

Substitute m = 4 and (1, 8) into y = mx+c

8 = 4(1) + c

8 - 4 = c

c = 4

Get the required equation

y = 4x + 4

Hence the required linear equation is y = 4x+4

Prism A is a triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The prism has a height of 4 meters. Prism B is a rectangular prism with length of 8 meters, width of 2 meters, and height of 8 meters.

Which prism has the least volume?

Prism ________

Answers

Answer:

Step-by-step explanation:

Prism A Volume

The Column of Prism A = Base (Area) * Height.

I think you have to assume that the triangle is a right triangle.

Area of the triangle = 1/2 * 9 * 7

Area of the triangle = 1/2 63

Area of the triangle = 31.5

Volume of the Prism = area of the triangle * thickness

Volume of the prism = 31.5 * 4

Volume of the prism = 126 m^3

Prism B = L * w * h

Prism B = 8 * 8 * 2

Prism B = 128

Prism A has the least volume by just a little.
