Answer:

Hours are equal: 7.2

Cost of service are equal: 51.4

Step-by-step explanation:

Happy Paws:

y = 4.5h + 19

Woof Watchers:

y = 5.75h + 10

To solve for the hours are equal:

y = 4.5h + 19

y = 5.75h + 10 (Multiply by -1)

y = 4.5h + 19

-y = -5.75h - 10

0 = -1.25h + 9

-9 = -1.25h

h = 7.2

To solve for when the services are equal:

y = 4.5h + 19

y = 4.5(7.2) + 19

y = 32.4 + 19

y = 51.4

$0.70 is the answer........

Answer:

306 inches

Step-by-step explanation:

80% = 0.8

170 inches × 80% = 170 × 0.8 = 136

The truck is 80% longer than the boat. 80% of the boat is 136.

So, the boat is 170 inches + 136 inches = 306 inches.

Answer:

C) 136 inches.

Step-by-step explanation:

To find this just do the equation:

170 x 0.8 = ?

This equation tells use how much 80% of 170 is. Also, before doing an equation like this, change the percentage into a decimal like 80% to 0.8.

So,

170 x 0.8 = 136

170 + 136 = 306

So the boat is 306 inches.

area is length times width, so if you do opposite equations, and divide 91 by 13, that will be your answer. 7.

This question is incomplete, the complete question is;

Question 1: The National Assessment of Educational Progress (NAEP) is administered annually to 4th, 8th, and 12th graders in the United States. On the math assessment, a score above 275 is considered an indication that a student has the skills to balance a checkbook. In a random sample of 500 young men between the ages of 18 and 20, the mean NAEP math score is 272 with standard deviation of 78.

Do we have evidence to support the claim that young men nationwide have a mean score below 275. The level of significance is 5%

Answer:

p-value ( 0.2 ) > significance level (0.05 )

Fail to reject H₀ at ∝ = 0.05

Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Step-by-step explanation:  

 Given the data in the question;

Null hypothesis             H₀ : μ = 275  

Alternative hypothesis Hₐ : μ < 275

mean x' = 272

standard deviation σ = 78

sample size n = 500

Test Statistics

z = (x'-μ) / (σ /√n )

we substitute

z = (272-275) / (78 /√500 )

z =  -3 / 3.488266

z = - 0.86

from table;

p-value = 0.19489 ≈ 0.2

Hence; p-value ( 0.2 ) > significance level (0.05 )

Fail to reject H₀ at ∝ = 0.05

Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Answer:

If the slope is 11, and the y-intercept is (0, 2), the answer is:  y = 11x + 2.

The picture says the slope is -1/4. The answer to the question in the picture is: y = -1/4x + 2.

Step-by-step explanation:

Slope form is

y = mx + b.

m is the slope.

b is the y value of y intercept.

Answer:

Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.

Answer:

3

Step-by-step explanation:

There a 5 chains (each with 3 links). We take one chain and cut all three links. Now we are left with only four chains. This requires only 3 joints. Exactly the number of links I have. Therefore, the lowest number of cuts is three.

The number of different links must be cut a welded should be considered as the 3.

Since

Zack has 13 chains at 5 links each. He wants to combine them

So here we considered only one chain and then cut off all 3 links

So the remaining should be four chains and it needs only 3 joints.

hence, The number of different links must be cut a welded should be considered as the 3.

Answer:

The conjugate of 2i + 9 = -2i + 9

Product of (2i+9) and (2i+9)  is 36i + 77

Step-by-step explanation:

Given - 2i + 9

To find - Find the conjugate and product of the following surds

Proof -

We know that,

The sum and difference of two simple quadratic surds are said to be conjugate surds to each other.

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i ).

So,

The conjugate of 2i + 9 = -2i + 9

Now,

Product of surd (2i+9) is

(2i+9)(2i+9) = 2i(2i) + 2i(9) + 9(2i) + 9(9)

                  = 4i² + 18i + 18i + 81

                  = -4 + 36i + 81          { because i² = -1 }

                  = 77 + 36i

⇒Product of (2i+9) and (2i+9)  is 36i + 77

Answer: x=-4

Step-by-step explanation:

Given

x=-4y

y=2x+9

Rephrase equation to find y value in terms of x

y=-x/4

y=2x+9

Use substitution (substitute value of y)

2x+9=-x/4

Multiply -4 on both sides

-4(2x+9)=-4(-x/4)

-8x-36=x

Add 8x on both sides

-8x-36+8x=x+8x

-36=9x

Divide 9 on both sides

-36/9=9x/9

x=-4

The population of The Colony after 2 hours is d. 64​

The given parameters are:

Initial, a = 1

Rate, b = 2 every 20 minutes

An exponential function is represented as:

y = ab^x

So, we have:

y = 1 * 2^x

y = 2^x

There are six 20 minutes in 2 hours.

This means that:

x = 6

So, we have:

y = 2^6

Evaluate

y = 64

Hence, the population of The Colony after 2 hours is d. 64​

Answer is b) 20.

Step-by-step explanation:

Mean is 0.43 kg.

0.43+0.1+0.1= 0.45

0.45 is two standard deviation above.

All that are below mean is 50%,

Two standard deviation above is 95%/2=47.5%

50%+47.5% =97.7% are  balls that are less than 0.45 kg.

100%-97.7%=2.5% balls that are more than 0.45 kg

2.3%=0.025

800*0.025 = 20 soccer balls weigh more than 0.45 kg
