Answers

Answer:

1.625

Step-by-step explanation:

First we need to find the mean of this data set

29+32+33+28+30+30+29+33=244

Then we divide 244 by the amount of numbers in the set

244/8=30.5

Then we need to find the deviation of each number

29 | 32 | 33 | 28 | 30 | 30 | 29 | 33

1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5

Then we take the mean from this set of data

1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13

Then divide

13/8=1.625

I hope this helps :)

- The position of an object moving in a straight line
is given by s = 2t^2 - 3t, where s is in meters and t
is the time in seconds the object has been in
motion. How long (to the nearest tenth) will it
take the object to move 11 meters?


PLEASE HELP AND SHOW WORK ILL GIVE 20 PTS

Answers

Answer:

s(t) = 2t^2-3t

19 = 2t^2-3t

2t^2-3t-19=0

t = [3 +- sqrt(9-4*2*-19)]/4

t = [3 +- sqrt(161)]/4

t = [3 +- 12.6886]/4

Positive answer:

t = [3+12.6886]/4

t = 3.9221 seconds

Answers

Answer:

answer is 81

Step-by-step explanation:

54 × 1.5=81

The first step is to enlarge 6 inches. 6 inches enlarged by 1.5 = 9 inches
Then 9 inches. 9 inches enlarged by 1.5 = 13.5 inches


Next, you multiply to find the area. area = 9 × 13 = 121.5 square inches

2. What is the solution to this equation?

plz help :(

Answers

okay for number 1, even though there isn’t a question to answer, my best guess would be H, 66 in^3.

i multiplied the height (6) by the base (11) to get the 66.

———

for number 2, here’s what you should do.
2x + 10 = 28
- 10 -10
(subtract 10 from both sides of the equal sign)

you should get..
2x = 18
divide by 2 to get the x by itself..
x=9

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square?

A square with a side length of 8 units is shown. A diagonal is drawn with one section shaded inside the figure.

fraction 1 over 4 ⋅ 4 ⋅ 4
fraction 1 over 2 ⋅ 8 ⋅ 8
fraction 1 over 4 ⋅ 8 ⋅ 8

Answers

Answer:

The answer is b and fraction 1 over 2 ⋅ 8 ⋅ 8

Step-by-step explanation:

I'm pretty sure

Answer:

Hence, option 3 is correct.

Step-by-step explanation:

Given,

Side of a square = 8 units

Also,

The shaded triangles base = Height of the triangle = Side of the square = 8 units.

(Sides of a square are always same)

Hence, area of the shaded triangle will be,

[tex] = \frac{1}{2} . \: base \: . \: height[/tex]

[tex] = \frac{1}{2} . \: 8 \: . \: 8 \: (ans)[/tex]

Find the annual interest rate.

I= $164.50, P= $940, t= 2.5 years

___%

Answers

Answer:

250.35

Step-by-step explanation:

The interest rate is about 7% per year.

What is simple interest?

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

We can use the formula for simple interest to find the annual interest rate:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed or invested), r is the annual interest rate as a decimal, and t is the time in years.

Plugging in the given values, we have:

164.50 = 940 * r * 2.5

Dividing both sides by 940 * 2.5, we get:

r = 164.50 / (940 * 2.5)

r ≈ 0.07

Multiplying by 100 to convert to a percentage, we get:

r ≈ 7%

Therefore, the annual interest rate is approximately 7%.
