What is the measure of x? Image below
Answer:
Angle x= 76
Step-by-step explanation:
angle DIJ = 180-107
=73
angle x =angle DJI =180-31-73
=76
both angles x and DJI are equal because they both intersect with each other.

The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on visual inspection of the dot plots, which of the following groups appears to have the longer average forearm length?
A. Group A, because no child in the group has a forearm length longer than 11 inches
B. Group B, because two children have a forearm length longer than 11 inches
C. Group A, because three children in the group have the least forearm length of 9 inches
D. Group B, because a child in the group has the least forearm length of 9 inches
Answer:
The correct option is B.
Step-by-step explanation:
From the given dot plot we can say that 3 children have 9 in. long forearm, 4 children have 10 in. long forearm and 3 children have 11 in. long forearm.
The average of length of forearms of Group A is
The average of length of forearms of Group A is 10 inches.
From the given dot plot we can say that 3 children have 10 in. long forearm, 5 children have 11 in. long forearm and 2 children have 12 in. long forearm.
The average of length of forearms of Group B is
The average of length of forearms of Group B is 10.9 inches.
10.9>10 it means Group B has longer average forearm length. It is true because two children have a forearm length longer than 11 inches.
Therefore the correct option is B.

Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2
Step 2: Find area of outer shape =
25 ft +11 ft = 36 cm2
Step 3: Area of shaded region = area of outer shape – area of inner square
= 36 ft2 – 48 ft2
= 12 ft2
Explain the difference between center and shape of a data set.
The center is the median and/or mean of the data. And, the shape describes the type of graph.
There are many shapes data sets could show. One example would be asymmetric data set. In this case, both sides of the picture would look almost exactly or could be exactly (rarely) alike. In this case, the mean could be used as a measure of center.
When the data is skewed right or left, the pictorial representation of the data will show fewer data points on the side where it is skewed and more data on the opposite side. The tail will be longer on the right if it is skewed right and vice versa.
In skewed right data, the mean will be greater than the median, and if the data is skewed left, the mean will be less than the median. The mean is not the measure of the center when the data is skewed.

27. The fifth and thirteenth terms of an arithmetic sequence are 5 and 77 , respectively. Find the first term and the tenth term.
Answer:
if the first term is 13, the second will be 13+x, the third 13+2x and so on, the tenth term will be 13+9x=40 9x = 27 x = 3 so the difference between the terms is 3 the sum of the first 10 terms is 13*10 + (x+2x+…+9x) = 130 + 45x = 130 + 45*3 = 130 + 135 = 265

35. Cindy walks at a constant rate of 2 miles per hour. She leaves home to walk to her friend Jenny's house at 9 am. When she is halfway there, she thinks that she left her phone at home. She turns around and begins to walk back home, but when she is halfway home (from where she turned around), she finds her phone. She turns back around to walk to Jenny's and arrives there at 10 am. How far apart are Cindy's house and Jenny's house?
Hint: Draw a diagram!
Answer:
you're screwed
Step-by-step explanation:
don't forget your phone so anyon doesn't ever have to do this
Cindy's house and Jenny's house are 1.33 miles distant from each other.
What is speed?Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.
The SI derived unit for speed is meter per second (m/s).
Given,
Cindy leaves house at 9 am and reaches to jenny house at 10 am
Let the distance between Cindy and Jenny house is x
First, Cindy walks half way to jenny house = x/2
then Cindy take U-turn and walks half way to home = x/4
again Cindy take U-turn and reaches jenny house = 3x/4
Total distance walked by Cindy = x/2 + x/4+ 3x/4
= x/2 + x
= 3x/2
Speed of jenny is 2 miles per hour
She walks 3x/2 distance and reaches Jenny house in one hour
⇒ 3x/2 = 2
⇒ 3x = 4
⇒ x = 4/3
⇒ x = 1.33 miles
Hence, distance between Cindy's and jenny's house is 1.33 miles.

Write and solve a proportion to answer the question. (Skills Review Handbook) 21. 70% of what number is 98?
Answer:
451.61
Step-by-step explanation:
1) Set a linear equaion
[tex] \frac{98}{x} = \frac{21.70}{100} [/tex]
2) Cross multiply
[tex]21.70x = 98 \times 100[/tex]
3) Multiple the right side
[tex]21.70x = 9800[/tex]
4) Divide both side by 21.70
[tex] \frac{21.70x}{21.70} = \frac{9800}{21.70} [/tex]
5) Solve the linear equation
[tex]x = 451.6129032[/tex]
[tex]x≈451.61[/tex]
Then 21.70% of 451.61 is 98
