Find the output, y, when the input, x, is 7.
y=__

Answer:

90°-33°=57°

57=2x+1

-1. -1

56=2x divide both sides by 2

28=x

x =28

Answer:

x = 28

Step-by-step explanation:

Both of these would add up to 90 degrees.

Equation                              → 2x + 1 + 33 = 90

Add like terms                     → 2x + 34 = 90  

Subtract both sides by 34  → 2x + 34 - 34 = 90 - 34

Divide both sides by 2        → 2x = 56

                                              → x = 28

Step-by-step explanation:

If there are 8 players on a team, and a total of 24 teams, you will need to multiply 8 x 24 to find the answer.

8 x 24 = 192 players can sign up for the league.

(hope this helps can i plz have brainlist :D hehe)

Answer:

192 players

Step-by-step explanation:

8x24=192

8 is the 8 players per team, since there are 24 teams available, multiply 8 by 24.

Answer:

6π units

Step-by-step explanation:

Given::

Radius = 4

Angle measure of partial circle (θ) = 360° - right angle = 360° - 90° = 270°

Arc length = θ/360 × 2πr

Plug in the values

= 270/360 × 2 × π × 4

= 0.75 × 8 × π

= 6π units

3*10 = 30 - 48*2 = 96

30 - 90

= -60

Answer:

8: 0,-2  9: 7,-3  10: 7,1/2

Step-by-step explanation:

Hello, for question 8 (the top equation), you trying to find y and x so lets find y first. You need y to be by itself so you divide all the numbers by -3 like this:

6x/-3-3y/-3=6/-3

The equation simplifies to -2x+y=-2. You need y to be by itself so you move it to the other side and you get -2 for y. Now you need x. Go to the second equation and take the number that is y and plug it into the equation like this:

6x+8(-2)=-16

Multiply 8 with -2 which is -16. Then, you add -16 with -16 which makes 0.

6x=0

You then divide 6 on both sides and x is 0. You basically do the same process for questions 9 and 10 which are 7,-3 and 7,1/2. And your done!

Answer:

9^5

Step-by-step explanation:

9 x 9 x 9 x 9 x 9 can be written as an exponent form 9⁵.

To rewrite 9 x 9 x 9 x 9 x 9 using an exponent, we can represent the repeated multiplication with the base 9 raised to the power of 5. Here's how:

9 x 9 x 9 x 9 x 9 = 9⁵

In this expression, the base is 9, and the exponent is 5. The base represents the number being multiplied repeatedly, and the exponent represents the number of times it is multiplied.

Using the exponent notation, we can simplify and express the result more concisely. The exponent 5 indicates that the base 9 is multiplied by itself five times.

Therefore, 9 x 9 x 9 x 9 x 9 can be written as 9⁵.

Answer and Explanation:

Please find full question attached

From the bar chart, we can see that the the interval 130-150 has two bars in it:

Interval 130-140 with the highest frequency of 5

Interval 140-150 with frequency of 2

Therefore to find the percentage between 130-150 we add up the frequencies 2+5=7 and divide by the total frequency of 15 people all multiplied by 100

=7/15×100= 46.67%

Percentage of participants with heart rate between 130 and 150 =46.67%

x = 3

Step-by-step explanation:

3*3*3 = 9*3 = 27

Step-by-step explanation:      

Let's solve your equation step-by-step.

[tex]x^3 =27[/tex]

Step 1: Take cube root.

[tex]x = (27)^(1/3)[/tex]

[tex]x=3[/tex]

Explanation in words (Short Form)

- Move the variable to the left and the other values to the right to determine the value of x. To ascertain the outcome, simplify the values.

- In this equation (x^3=27), we can solve this equation by taking the cube root and then ascertaining the outcome.  The answer will result as x = 3 at the end for the following equation: x^3=27 to finding the value for x.

Answer:

Answer:

a. Assume that the population has a normal distribution.

b. The 90% confidence interval of the mean sale time for all homes in the neighborhood is between 219.31 days and 240.69 days.

Step-by-step explanation:

Question a:

We have to assume normality.

Question b:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.645\frac{35}{\sqrt{29}} = 10.69[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 230 - 10.69 = 219.31 days.

The upper end of the interval is the sample mean added to M. So it is 230 + 10.69 = 240.69 days.

The 90% confidence interval of the mean sale time for all homes in the neighborhood is between 219.31 days and 240.69 days.

Answer:

72 mi is the answer.

Step-by-step explanation:

a = 30 mi

b = ?

c = 78 mi

According to the Pythagoras theorem,

a² + b² = c²

30² + b² = 78²

900 + b² = 6084

b² = 6084 - 900

b² = 5184

b = 72 mi

∴ the eastbound airplane has travelled 72 mi.

Answer:

160 cars

Step-by-step explanation:

The computation of the number of more cars he washed this year is given below;

Last year, he washed 20 cars a week so on yearly basis he washed

= 20 cars × 52 weeks

= 1,040 cars

And, this year he washed 1,200 cars

So, the number of more cars he washed this year is

= 1,200 cars - 1,040 cars

= 160 cars

Answer:

(18.1361 ; 19.5639) ;

using a smaller sample will widen the margin

Step-by-step explanation:

Given :

Xbar = 18.85

Standard deviation, s = 1.75

Sample size, n = 40

Confidence interval is obtained using the relation :

Xbar ± Margin of error

Margin of Error = Zcritical * s/ √n

Zcritical at 99% = 2.58

Margin of error = 2.58 * (1.75/√40) = 0.7139

Lower boundary = 18.85 - 0.7139 = 18.1361

Upper boundary = 18.85 + 0.7139 = 19.5639

(18.1361 ; 19.5639)

B.)

The sample size, n being the denominator in the margin error formula increases the error value as it reduces or decreases in value Hence widens the interval. Conversely, increasing the sample size reduces the error margin value and ultimately narrows the interval.

Therefore, using a smaller sample will widen the margin
