In the grade 9, the ratio of girls to boys is 17:8. What percent of the grade 9 are boys?

Answer:

D

Step-by-step explanation:

Answer:

the absolute value of the number

Step-by-step explanation:

for example if the absolute value of 3 is 3 because the distance of 3 from zero on the number line is 3 places to the right.

Answer:

a = -10

b = -5

c = -1008

d =-1000

Step-by-step explanation:

a = -30/3

b = 45/-9

c = -84x12

d = -88000/88

Answer: A = -10. B = 54. C = -1008. D = -1000

Step-by-step explanation:

a * 3= - 30  You must divide 3 on both sides in order to get the a alone.

a * 3/3= - 30/3   And once you divide 3 from both sides you end up with

a= -10  And a equals negative 10

-9 * b = 45  You have to add 9 to both sides to get b alone.

-9 +9 *b= 45 +9 And you end up with with

b= 54   b equals 54

-84 * 12= c  Since the c is already alone all you have to do is solve the problem

-84 time 12 eqauls -1008, its a negative because it has a negative in the equation

-1008= c

d *88 = -88,000  You have to divide 88 from both sides to get the d alone.

d * 88/88 = -88,000/88. And you end up with

D = -1000  d equals negative 1000

Answer:

11610

Step-by-step explanation:

First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.

Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.

Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.

Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.

This might help you with your question 2 numbers inside of scientific notation have to be manipulated in order for their own foundations to have the same exact exponent

To be added or subtracted, two numbers in scientific notation must be manipulated so that their bases have the same exponent--this will ensure that corresponding digits in their coefficients have the same place value.

Answer:

The answer is 3.

Step-by-step explanation:

You have to substitute h = 5 into the fraction :

[tex] \frac{ {h}^{2} - 1}{h + 3} [/tex]

Let h = 5,

[tex] = \frac{ {5}^{2} - 1}{5 + 3} [/tex]

[tex] = \frac{25 - 1}{8} [/tex]

[tex] = \frac{24}{8} [/tex]

[tex] = 3[/tex]

Answer:

Step-by-step explanation:

[tex]\frac{h^2-1}{h+3 } \\when~h=5\\\frac{5^2-1}{5-1} =\frac{24}{4} =6[/tex]

Answer:

Surface area is found:

Surface Area = 1700 cm²

Step-by-step explanation:

(The cereal box is shown in the ATTACHMENT)

The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.

L = length = 20 cm

H = height = 30 cm

W = Width = 5 cm

A(1) = L×H

A(1) = 20×30

A(1) = 600 cm²

As the measurements of the side at the back of side 1 has the same measurement of side 1. then:

A(2) = 600 cm²

A(3) = L×W

A(3) = 20×5

A(3) = 100 cm²

As the measurements of the side at the back of side 4 has the same measurement of side 4. then:

A(4) = 100 cm²

A(5) = H×W

A(5) = 30×5

A(5) = 150 cm²

As the measurements of the side at the back of side 5 has the same measurement of side 5. then:

A(6) = 150 cm²

Adding areas of all the sides

A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150

Surface Area = 1700 cm²

Answer:

580

Step-by-step explanation:

Area of a rectangle = length x width

3x20=60

2x60=120

The bottom and the top are both 3 by 10 rectangles

120+60+400=580

580

So the right answer is 18

Answer:

(a) Sample range appears to be a biased estimator since it consistently underestimated the population range.

Step-by-step explanation:

The sample ranges appear to be centered below 32

I got this right on Khan

In this exercise we have to use, in addition to the knowledge of statistics, the graph informed in the exercise in this way, we can say that:

Letter A

When we look at the graph, the maximum points are at 21 and 31, while the samples ranges appear to be centered below 32, that is we can say that the letter A is more appropietate.

Step-by-step explanation:

Answer:

(x (8 x^2 - 20 x + -33))/(2 (x - 3))

Step-by-step explanation:

Simplify the following:

4 x^2 + 2 x - (42 x)/(4 (x - 3))

The gcd of 42 and 4 is 2, so 42/4 = (2×21)/(2×2) = 2/2×21/2 = 21/2:

4 x^2 + 2 x - x/(x - 3) 21/2

Put each term in 4 x^2 + 2 x - (21 x)/(2 (x - 3)) over the common denominator 2 (x - 3): 4 x^2 + 2 x - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)):

(8 x^2 (x - 3))/(2 (x - 3)) + (4 x (x - 3))/(2 (x - 3)) - (21 x)/(2 (x - 3))

(8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2 + 4 (x - 3) x - 21 x)/(2 (x - 3)):

(8 x^2 (x - 3) + 4 x (x - 3) - 21 x)/(2 (x - 3))

Factor x out of 8 (x - 3) x^2 + 4 (x - 3) x - 21 x, resulting in x (8 (x - 3) x^(2 - 1) + 4 (x - 3) - 21):

(x (8 x^(2 - 1) (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))

2 - 1 = 1:

(x (8 x (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))

8 x (x - 3) = 8 x^2 - 24 x:

(x (8 x^2 - 24 x + 4 (x - 3) - 21))/(2 (x - 3))

4 (x - 3) = 4 x - 12:

(x (4 x - 12 + 8 x^2 - 24 x - 21))/(2 (x - 3))

Grouping like terms, 8 x^2 + 4 x - 24 x - 21 - 12 = 8 x^2 + (-24 x + 4 x) + (-12 - 21):

(x (8 x^2 + (-24 x + 4 x) + (-12 - 21)))/(2 (x - 3))

4 x - 24 x = -20 x:

(x (8 x^2 + -20 x + (-12 - 21)))/(2 (x - 3))

-12 - 21 = -33:

Answer: (x (8 x^2 - 20 x + -33))/(2 (x - 3))

Answer:

7

Step-by-step explanation:

every o e move you make on x you make 7 on y. (made 2 moves in x and moved 14 on y) so if you moved 21 on y.... 21/7=3 so you move 3 on x so 4+3=7

Answer:

7, 12, 17, 21, 26, 31

Step-by-step explanation:

The first term in the sequence is 7 we know this cause the first equation (a1 = 7) is telling us what the first term is. To find the next term we use the second equation (an = an - 1 + 6) we us the first term subtract 1 and then add 6 ( 7 - 1 = 6, 6 + 6 = 12) the second terms is 12. To find the rest of the terms we continue using the second equation but instead of with 7 this time we use 12 then the next time 17 then 21 then 26 so on and so forth.

Answer:

47.5% of students fall within heights of 100 cm to 120 cm

Step-by-step explanation:

We are given that heights of Grade 1 students are normally distributed

Mean = [tex]\mu = 100 cm[/tex]

Standard deviation = [tex]\sigma = 10 cm[/tex]

a)

Empirical rule

68% of data lies within the first standard deviation from the mean i.e[tex].(\mu-\sigma , \mu+\sigma)=(100-10,100+10)=(90,110)[/tex]

95% of all the data will fall within two standard deviations  i.e.[tex](\mu-2\sigma , \mu+2\sigma)=(100-2(10),100+2(10))=(80,120)[/tex]

99.7% of data lies within the three standard deviations i.e.[tex]( \mu - 3 \sigma , \mu +3 \sigma)=(100-3(10),100+3(10))=(70,130)[/tex]

b)Percentage of students fall within heights of 100 cm to 120 cm

Using the normal distribution curve

Percentage of students fall within heights of 100 cm to 120 cm = [tex]\frac{1}{2} \times 95\% = 47.5\%[/tex]

Hence 47.5% of students fall within heights of 100 cm to 120 cm

Answer:

168

Step-by-step explanation:

Out of the 12 + 7 + 6 = 25 students sampled, 12/25 = 48% students liked Pop/Rock so 48% of 350 = 168 students is the answer.

Answer: 168 students

Step-by-step explanation:

12 + 7 + 6 = 25 so if we add all the numbers we get 25 then

we put it as 12/25 which is

48% students liked Pop/Rock

so then we do 48% of 350 or divide and get

168 students

Answer:

s = 11.

Step-by-step explanation:

To find the value of 's', we can first use the Supplementary Angles theorem. If '12s' is the measure of the angle outside of the triangle, the angle inside the triangle must be equivalent to '180-12s'.

Since the sum of all of the angles of the triangle must be 180°, we can set up an equation to solve for 's':

180 = 45 + 10s - 23 + 180 - 12s (Subtract both sides by 180)

Simplify:

0= 45 + 10s - 23 - 12s (Subtract both sides by 45, and add 23 to both)

-22 = 10s - 12s

-22 = -2s (Divide both sides by -2)

s = 11.
