Answer: 21

Step-by-step explanation:

[tex]N-\left(2\cdot \:7\right)=7[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]

[tex]N-2\cdot \:7=7[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:2\cdot \:7=14[/tex]

[tex]N-14=7[/tex]

[tex]\mathrm{Add\:}14\mathrm{\:to\:both\:sides}[/tex]

[tex]N-14+14=7+14[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]N=21[/tex]

Answer:

N = 21

Step-by-step explanation:

N - (2 × 7 ) = 7                                {2 × 7 = 14}

N - 14 = 7

   + 14   +14

----------------------

N = 21

Now we can substitute:

21 - (2 × 7 )

21 - 14 = 7

Hence, the answer is N = 21

Answer:

12cm

Step-by-step explanation:

The formula to find the area of a trapezoid is A = [tex]\frac{a + b}{2}[/tex]h. We replace the "a" and "b" with 6cm. We then replace the "h" with 12cm as your height is 12cm. The new formula is A = [tex]\frac{a + b}{2}[/tex]h = [tex]\frac{6 + 6}{2}[/tex] x 12. The answer to that equation is 12cm.

Initial Value= $200, Rate of Change= $10 per hour (or just $10)

Step-by-step explanation:

The initial value is what Jaylah started with, and in this case, she starts with $200.

The rate of change is how much Jaylah earns, in this case per hour. It says that she earns $10 an hour, so the rate of change is $10.

The number of times that it is likely to land in the shaded area will be 40 times out of 100 times.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

A dart is thrown at the board 100 times at random.

The number of times that dart hit the board is 40 times. Then the probability is calculated as,

P = 40 / 100

P = 2/5

P = 0.40 or 40%

Answer:

C. 43.6

Step-by-step explanation:

you need to take the area of each shape

lets do the skinny triangles first on the top and bottom of this shape.

so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3

because the formula of a triangle is half the base times height.

so we get 0.5 * 1.26 * 5.3 = 3.339

multiply it by two and we get 6.678

now lets find the area of the huge rectangle on the back/behind of the shape

3.3*5.3 = 17.49

now lets find the area of the two smaller rectangles

3.3 * 3.6 = 11.88

2.3 * 3.3 = 7.59

now lets add

6.678 + 17.49 + 11.88 + 7.59 = 43.638

round it to 43.6

Answer:

x=10.7, y=11300

Step-by-step explanation:

x%of 31 = 3.317

x/100×31=3.317

31x/100=3.317

31x= 3.317×100

x= 3.317 ×100/31

x =10.7

4407= 39% of y

4407= 39/100 × y

4407 =39y/100

4407×100=39y

4407 × 100/39=y

11300=y

Step-by-step explanation:

Answer:

Radius: about 1.42 mm

Step-by-step explanation:

First, you divide the circumference (8.9) by 3.14, or π.

Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)

Diameter (2.83439490446) divided by 2 = radius (1.41719745223)

Now, you have to round to the nearest hundredth.

1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer:

basketball

Step-by-step explanation:

i took the test :)

Basketball have most spread out.

Option B is correct.

A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.

We have

Basketball: mean absolute deviation of 4.6

Baseball: mean absolute deviation of 3.5

Soccer: mean absolute deviation of 1.2

As, a high mean absolute deviation tells us that many of the data values are spread out further from the mean.

Here Basketball have highest absolute deviation.

Thus, Basketball have most spread out.
