Item 15
A crowd-funding project has received $16,770, which is $1230 less than 90% of the goal amount. What is the goal amount?

Answer:

a=20 m²

b=21 cm²

c=36 dm²

Step-by-step explanation:

A) 12²+16²=a²

144+256=a²

400=a²

√400=a

a=20

B) 28²+b²=35²

784+b²=1225

b²=1225-784

b²=441

b=√441

b=21

C) c²+15²=39²

c²+225=1521

c²=1296

c=√1296

c=36

Answer:

The area of the circle is 531.14 square unis

Step-by-step explanation:

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

where r is the radius of the circle

Given that the diameter of the circle = 26 units, the radius can be determined by;

r = [tex]\frac{diameter}{2}[/tex]

 = [tex]\frac{26}{2}[/tex]

r = 13 units

So that,

Area of the circle = [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]

                             = [tex]\frac{22}{7}[/tex] x 169

                             = 531.1429

The area of the circle is 531.14 square unis.

Answer:

One pound can be written as 1.0 pounds, and moving the decimal place one place to the left gives you 0.10 pound, which is equal to one tenth of a pound. Convert 16 oz. to one sixteenth of an ounce by moving the decimal one place to the left.

The best-fitting regression model for the data plot given is linear decreasing. Therefore, option B is the correct answer.

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.

In the given graph, the data plot shows the decreasing order.

Therefore, option B is the correct answer.

Answer:what is this

Step-by-step explanation:

Answer:

[tex]4x^{6}2y^{-2}[/tex]

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is [tex]4(2x^{12}y^{16})[/tex]

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is [tex]8x^{12}4y^{16}[/tex].

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

[tex]\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}[/tex]

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is [tex]4x^{6}[/tex].

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is [tex]2y^{-2}[/tex]

The complete, simplified equation is [tex]4x^{6}2y^{-2}[/tex].

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

Answer:

12226.8

Step-by-step explanation:

Answer:

12226.8

Step-by-step explanation:

Answer:

8876-(3653 +2375)

Step-by-step explanation:

So your total is 8876. On the first and the second level of the game you scored 3653 and 2375. But when you where done playing the third level your total from all of the levels ended up to be 8876. So if you wanted to find how much points you got on level 3, then you would add 3653 + 2375, then suntract the total of that from 8876.

Answer: A

Step-by-step explanation:

Answer:

a) Upper Control Limit = 0.10

   Lower Control Limit = 0.01

b) The tech assistance process is stable and in control.

Step-by-step explanation:

Given - After a number of complaints about its tech assistance, a

            computer manufacturer examined samples of calls to determine

            the frequency of wrong advice given to callers. Each sample

            consisted of 100 calls.

SAMPLE             1   2   3   4   5   6   7   8   9  10 11 12 13 14 15 16

Number of errors 5  3   5   7   4   6   8   4   5    9   3   4   5   6   6   7

To find - a. Determine 95 percent limits.

              b. Is the tech assistance process stable (i.e., in control)

Proof -

z = 95% confidence interval

  = 1.96

⇒z = 1.96

Proportion of defects,P = total defectives/total observations

                                     = 0.0544

⇒P = 0.0544

Now,

Q = 1-P

   = 0.9456

⇒Q = 0.9456

Now,

Average sample size, N = 100

Standard deviation = [tex]\sqrt{\frac{P.Q}{N} }[/tex]

                             = 0.0227

Now,

Upper Control Limit = P + z(Standard deviation)

        = 0.0988

⇒Upper Control Limit = 0.0988 ≈ 0.10

And

Lower Control Limit = P - z(Standard deviation )

       = 0.0099

⇒Lower Control Limit = 0.0099 ≈ 0.01

∴ we get

Upper Control Limit = 0.10

Lower Control Limit = 0.01

b.)

Now,

it is clear that the fraction defective values are wit in upper an lower control limits.

So, The tech assistance process is stable and in control.

$96 was the total cost

The Kristen's paycheck for 39 hours is $321.75.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Kristen is paid $8.25 per hour.

Paycheck for 39 hours

= 39×8.25

= $321.75

Therefore, the Kristen's paycheck for 39 hours is $321.75.

D 103.0

Answer: D. [tex]y=\frac{1}{9} x^{2}[/tex]

Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).

Answer:

Adter ate [tex]\frac{1}{4}[/tex] of the remaining pie.

Step-by-step explanation:

equation:

⇒ [tex]\frac{3}{4} - \frac{1}{6}[/tex]

when subtracting fractions, make sure both denominators are the same, to do this, multiply the first fraction by 3 and the second fraction by 2

⇒ [tex]\frac{3}{4} x 3 - \frac{1}{6} x 2[/tex]

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

solve:

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

⇒ [tex]\frac{3}{12}[/tex]

simplify:

⇒ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
