A high school teacher recorded the number of hours each of his students spent on a social networking website in a particular week and related this with their scores on a math test they took at the end of the week. The data is represented in the scatter plot.

Qualitatively evaluate the information in the scatter plot. An acceptable estimate for the graph's correlation coefficient could be

Answer:

The height of the giraffe is 27.432 decimeters.

Step-by-step explanation:

To convert 1 foot to decimeters you would multiply by 3.048.

We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.

72 boys.

Step-by-step explanation:

no. of boys (initial) : no. of girls : no. of boys (final)

3 : 2

3 : 2

______________________________________

9 : 6 : 4

9u - 4u = 5u = 30

5u = 30

1u = 30/5 = 8

9u (initial no. of boys) = 8×9

= 72

99,000 / 6,700,000 = 99 / 6700

1.4776% of the shares are owned by the mutual fund

Answer:

53

Step-by-step explanation:

in rhombus, opp angeles are equal.

4x+9 =(11x-3)/2--ac bisects the angle dab

8x+18 = 11x-3

3x = 21

x=7

angle dab = 11*7-3/(2)= 77-3/(2)= 74/2= 37

total of angles = 180

74+2x = 180

2x = 106

x=53

Answer:

A. The triangles are not similar to each other.

Step-by-step explanation:

[] A triangle's angles all add up to 180°

-> For triangle ABC the angles are 80°, 40°, and unknown

-> For triangle DEF the angles are 80°, 70°, and unknown

[] For triangle ABC the angles are 80°, 40°, and unknown

-> 180° - 80° - 40° = 60°

-> Triangle ABC has angles of  80°, 40°, and 60°

[] For triangle DEF the angles are 80°, 70°, and unknown

-> 180° - 80° - 70° = 30°

-> Triangle DEF has angles of 80°, 70°, and 30°

[] A. The triangles are not similar to each other.

-> Since we do not have any side lengths, we must go off of AA (angle & angle) but as AA is not true, these triangles are not similar

Answer:

10.06 lbs of peanuts and 19.94 lbs of hazelnuts.

Step-by-step explanation:

lb=pound

30 lb mixture at $6.43/lb means that the total cost of the mixture is 30×6.43=192.9

Let H = weight of hazelnuts in the mixture.

Let P = weight of the peanuts in the mixture.

Set up a system of equations.

7H + 6.43P = 192.9

H + P = 30

Afterward, input the values into the equations above.

H = 30 - P

7(30-P) + 5.3P = 192.9

210 - 7P + 5.3P = 192.9

210 - 1.7P = 192.9

-1.7P + 210 = 192.9

-1.7P = 192.9 - 210

-1.7P = -17.1

P = -17.1 / -1.7 = 10.06

H = 30 - P = 30 - 10.06 = 19.94

Hence, the mixture contains 10.06 lbs of peanuts and 19.94 lbs of hazelnuts. Hope this helps and have a great day!

Answer : 0.02623

Answer:

48

Step-by-step explanation:

Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.

Here is 8 divided by 1/6 displayed mathematically in colors:

8

 ÷    

1

6

The numbers in 8 divided by 1/6 are labeled below:

8 = whole number

1 = numerator

6 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

8 x 6

1

 =  

48

1

Thus, the answer to 8 divided by 1/6 in fraction form is:

48

1

To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

48 / 1 = 48

The answer is rounded to the nearest two decimal points if necessary.

48/1 is an improper fraction and should be written as 48.

Answer:

It would be 66,000

Step-by-step explanation:

you round to the number next to you some saying I learned were 5 and above give it a shove 4 or less give it a ress.

example 598 round to nearest hundred would be 600 because the 9 is 5 and above so answer 600

Answer:

y = 1/2x + 2

Step-by-step explanation:

y = mx+b, where m is the slope, b is y-int, and y and x are variables.

Step 1: find the y-int: 2. Using this you can out rule C and D.

Step 2: find the RISE/RUN: 1/2. This is your slope.

Step 3: fill in your equation.

Answer:

Triangle A: Acute

Triangle B: Obtuse

Triangle C: Acute

Triangle D: Right

Step-by-step explanation:

Acute angle: 0°-90°

Right angle: 90°

Obtuse angle: 90°-180°

An acute triangle only has acute angles. A right triangle has one right angle and two acute angles. An obtuse triangle has one obtuse angle and two acute angles.
