Answer:

p=-60

Step-by-step explanation:

When you add a negative, you are just subtracting.

p/-2-27=3

p/-2-27+27=3+27

2(-p/2)=2(30)

-p=60

-p/-1=60/-1

p=-60

The sample of the speeds of 20 cars and at a 0.05 confidence level, we

have;

(a) There is not enough convincing evidence to suggest that the true mean speed of all cars travelling on Elm Street is more than 25 mph

(b) Type II error

(a) Based on the given data, using MS Excel, we have;

The sample size, n = 20

The mean, [tex]\overline x[/tex] = 25.86

The standard deviation of the sample, s = 2.284

The null hypothesis, H₀; [tex]\overline x[/tex] = 25 mph

Alternative hypothesis, Hₐ; [tex]\overline x[/tex] > 25 mph

Given that the sample size is less than 30, the t-test is used, and the t-score is found as follows;

[tex]t= \mathbf{\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}}[/tex]

Which gives;

[tex]t=\dfrac{25.86-25 }{\dfrac{2.284}{\sqrt{20}}} \approx \mathbf{1.684}[/tex]

Using a graphing calculator, we have;

The probability ≈  0.054

The critical-t ≈ 1.729

Given that the probability is larger than the significance level, we fail to

reject the null hypothesis.

There is not enough convincing statistical evidence to conclude that the

true mean of all cars travelling on Elm Street is more than 25 mph.

(b) The type of error is Type II error, given that there is a possibility that

the null hypothesis is failed to be rejected when it is actually false.

Given that the sample size is less than 30, it may be insufficient for the

Central Limit Theorem to be in effect.

The value of money Brianna need to invest is,

⇒ P = $99,259

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Brianna is going to invest in an account paying an interest rate of 5.2% compounded continuously.

Here, We have;

Final amount (A) = $134,000

Time (n) = 6 years

Rate (r) = 5.2%

We know that;

⇒ Amount = P (1 + r)ⁿ

Substitute the values we get;

⇒ 134,000 = P (1 + 0.052)⁶

⇒ 134,000 = P (1.052)⁶

⇒ P = 134,000 / 1.35

⇒ P = $99,259

Thus, The value of money Brianna need to invest is,

⇒ P = $99,259

Answer:

The answer is D

Step-by-step explanation:

First, find a and b from the given points.

y = abx

5 = ab3

10 = ab4

b = 10/5 = 2

5 = a(23)

a = 5/8

y = (5/8) 2x

Test the choices:

x = 2 ⇒ y = 5/2

This rules out (a) and (b).

x = 5 ⇒ y = 20

Answer:

The amount increased by 102 units. The amount has increased by 120%

Step-by-step explanation:

187-85=102

85x=187

(187/85)-1=1.2

1.2*100=120

Answer:

Step-by-step explanation:

187 - 85 = 102

( 102 ÷ 85 ) × 100 = 120

Answer:

9ft

Step-by-step explanation:

14 ft (top) - 5ft (bottom) = missing side (which is 9ft)

Answer:

9ft

Step-by-step explanation:

suppose that the side of 7ft was dragged to the right till it meets the side of 4ft

and the unknown side was dragged downwards till it meets the side of 5ft

Then, also considering that all angles are right angles, this structure becomes a square.

So the answer is 14ft - 5ft = 9ft

We have two flower beds in this example, the first has a perimeter of 100 feet, and the second has a perimeter of 180 feet

The total is 280 feet

Given Data

Dimension of the first flower bed

Length = 17 feet

Width = 33 feet

Perimeter = 2L + 2W

Perimeter = 2*17 + 2*33

Perimeter =  34 + 66

Perimeter = 100 feet

Dimension of the second flower bed

Length = 40 feet

Width = 50 feet

Perimeter = 2L + 2W

Perimeter = 2*40 + 2*50

Perimeter = 80 + 100

Perimeter = 180 feet

The total length will be 100+180 = 280 feet

Given that triangles OPQ and RST are similar triangles, the measure of side ST is: 75.3.

The ratio of the corresponding sides of two similar triangles are always equal, meaning the sides are proportional to each other.

Given:

Since Triangle OPQ is similar to triangle RST, therefore:

RS/OP = ST/PQ

Substitute

RS/17 = 31/7

Cross multiply

RS = (31 × 17)/7

RS = 75.3
