Answer:

0.00003 and 0.03

Step-by-step explanation:

Answer:

y = 1/2x + 2

*view the attached graph to double check the answer*

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

y = mx + b

y = 1/2x + b

(2, 3) ==> substitute the numbers into the equation

y = 1/2x + b

3 = 1/2(2) + b

3 = 1 + b

-1   -1

2 = b

Our final equation: y = 1/2x + 2

Check your answer using (2, 3):

y = 1/2x + 2

3 = 1/2(2) + 2

3 = 1 + 2

3 = 3

This statement is correct

Answer:

Jill's is the longest.

if jeffs is 0.9 times the length of jacks, his is lesser than jacks. e.g. 2×0.9=1.8. Jeff's will always be shorter. since we know Jacks is over 1, Jill's will always be taller because 2×1.08=2.16 or Jill's length.

Answer:

A: 1.5

B: A = n/1.5

C: This means every bowl you make, you would need 1.5 pounds of clay.

Step-by-step explanation:

A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.

4.5-0 = 4.5

3-0 = 3

4.5/3 =1.5

B:

A = n/1.5

C:

The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.

This means every bowl you make, you would need 1.5 pounds of clay.

Answer:

86.7

Step-by-step explanation:

L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7

The surface area of the  square pyramid is 92 square centimeters.

The given figure is a square pyramid.

We have to find the surface area.

Surface area = a² + 2a√(a²/4 + h²)

a is 5.1 cm and h is height which is 5.95 cm.

Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)

=26.01 + 10.2 √(26.01 /4 +35.4025)

=26.01+10.2 √6.5025+35.4025

=26.01+10.2√41.905

=92 square centimeters.

Your answer is C

Step-by-step explanation:

Multiply -33 x 11

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

The answer is

→ [tex]x=-8[/tex]

Step-by-step explanation:

Given: [tex]\frac{-72}{x} = 9[/tex]

[tex]\frac{-72}{x} = 9[/tex]

Step 1: Multiply all terms by the same value to eliminate fraction denominators.

[tex]\frac{-72}{x} = 9[/tex]

⇒ [tex]x * \frac{-72}{x} = x * 9[/tex]

Step 2: Cancel multiplied terms that are in the denominator.

[tex]x * \frac{-72}{x} = x * 9[/tex]

⇒ [tex]-72 = x * 9[/tex]

Step 3: Re-order terms so constants are on the left.

[tex]-72 = x * 9[/tex]

⇒ [tex]-72 = 9x[/tex]

Step 4: Divide both sides by the same factor.

[tex]-72 = 9x[/tex]

⇒ [tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

Step 5: Simplify.

[tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

⇒ [tex]-8 = \frac{9x}{9}[/tex]

[tex]-8 = \frac{9x}{9}[/tex]

⇒ [tex]-8 = x[/tex]

[tex]-8x = x[/tex]

⇒ [tex]x = -8[/tex]

Hence, [tex]x = -8[/tex] is your answer.

Answer:

part a. she has an 8 out of the 15 counters chance at getting red. part b. she has a chance of 262 times out of the 300 to get red

Step-by-step explanation:

i hope this helps and i'm sorry if it's wrong have a lovely day

The probability that it will be red is 8/15.

The number of times out of 300 Taylor will pick a red counter is 160.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

Taylor has a bag containing 15 counters.

First, the probability that it will be red

= 8/15

Now, if she repeats 300 times then

= 8/15 x 300

= 8 x 20

= 160

Answer:

Interquartile Range =  71

Step-by-step explanation:

The interquartile range is the middle 50% of the data set. First you calculate the location of the 3rd quartile (75% of the data set) by computing:

LQ3 = (75/100)(n + 1) -> here n is the number of observations you have, so 15. You can now compute LQ3 = (75/100)(16) = 12

The data at location 12 of your data set is 170.

Now you compute the 1st quartile (25% of the data set):

LQ1 = (25/100)(16) = 4

The data at location 4 of your data set is 99.

The difference between the 3rd quartile (170) and the 1st quartile (99) is your interquartile range:

IQR = 170 - 99 = 71
