What does this symbol ± mean?

Answer:

Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.

Answer:

b.) because it is over 90*

Step-by-step explanation:

Answer:

0.5

Step-by-step explanation:

Distance of OL = 0 - (-5)

                         = 0 + 5

                         = 5

Distance of OK = 2(5)

                          = 10

Gradient = [tex]\frac{rise}{run}[/tex]

               = [tex]\frac{0-(-5)}{10-0}[/tex]

               = [tex]\frac{5}{10}[/tex]

               = 0.5

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Answer:

c is the correct answer i took the test

Step-by-step explanation:

The gender that shows greater variability in their playing time is C. Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

For the males, the interquartile range will be:

= Third quartile - First quartile

= 17 - 9

= 8

For the females, the interquartile range will be:

= Third quartile - First quartile

= 15 - 3

= 12

Therefore, girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

Step-by-step explanation:

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

The answer is D.

The solution is, The graph that best approximates the line of best fit is option D.

Here, we have,

we know that,

Line of Best Fit:

This refers to the line that is used in a scatter plot to show and indicate a relationship between the points so that the number of points above the line is equal to the points below the point.

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

Hence, from the given illustration of graphs, we can see that using the eyeball method, we can see that the number of points in option D is best balanced between the line above and below.

The answer is D.

#SPJ7

Answer:

Step-by-step explanation:

The equation of a line is:

                          y - y₀ = m(x - x₀)

where m is the slope and (x₀, y₀) is the point which the line passes through

The product of slopes of two perpendicular lines is  -1

so if given lines slope is ¹/₇ them:

     ¹/₇·m = -1

        m = -7

(3, -7)     ⇒    x₀ = 3,  y₀ = -7

Therefore:

               y - (-7) = -7(x - 3)

                y + 7 = -7(x - 3)

Answer:

Simplified this is -304 + 38m = 52 + 26m

m in the equation is 29 2/3

Step-by-step explanation:

Reorder the terms:

19(-16 + 2m) = 13(2m + 4)

(-16 * 19 + 2m * 19) = 13(2m + 4)

(-304 + 38m) = 13(2m + 4)

Reorder the terms:

-304 + 38m = 13(4 + 2m)

-304 + 38m = (4 * 13 + 2m * 13)

-304 + 38m = (52 + 26m)

Simplfied answer:

-304 + 38m = 52 + 26m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-26m' to each side of the equation.

-304 + 38m + -26m = 52 + 26m + -26m

Combine like terms: 38m + -26m = 12m

-304 + 12m = 52 + 26m + -26m

Combine like terms: 26m + -26m = 0

-304 + 12m = 52 + 0

-304 + 12m = 52

Add '304' to each side of the equation.

-304 + 304 + 12m = 52 + 304

Combine like terms: -304 + 304 = 0

0 + 12m = 52 + 304

12m = 52 + 304

Combine like terms: 52 + 304 = 356

12m = 356

Divide each side by '12'.

m = 29.66666667

Simplifying

m = 29.66666667 = 29 2/3

Step-by-step explanation:

Given

[tex]\frac{x-11}{2}[/tex] - [tex]\frac{x-3}{5}[/tex] = 2

Multiply through by 10 ( the LCM of 2 and 5 ) to clear the fractions

5(x - 11) - 2(x - 3) = 20 ← distribute and simplify left side )

5x - 55 - 2x + 6 = 20

3x + 49 = 20 ( add 49 to both sides )

3x = 69 ( divide both sides by 3 )

x = 23

At Irtaza's Deli

Step-by-step explanation:

For this you should find the unit price and whichever is less is where you should go.

(1) Irtaza Deli:

First I would round the 5.99 to 6 then we'll do 6 divided by 7.

[tex]\frac{6}{7}=.8571428571=.86[/tex]

(2) Brianna's Food Mart:

First I would round the 8.99 to 9 then we'll do 9 divided by 10.

[tex]\frac{9}{10}=.9[/tex]

Now let's compare:

So the first store sells oranges for $.86 and the second store sells them for $.90. I don't know about you but I would go to the first store they would be much more cheaper.

14 pounds of meat

Step-by-step explanation:

Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue

We have to find the sum of the the total pounds of meat.

This is calculated as:

4 5/6 pounds + 3 1/3 pounds + 5 5/6 pounds

[(4 + 3 + 5) + (5/6 + 1/3 + 5/6)] pounds

The Lowest Common Denominator

= 6

Hence:

[12 + (5 + 2 + 5 /6)] pounds

= 12 + 12/6

= 12 + 2

= 14 pounds of meat

Hence, Jose has 14 pounds of meat

Answer:

Jerry's current balance is $41.

$52 - $30 = $22

(Current balance)

$65 + $22 = $87

$25 + $16 = $41
