A student took 5 test in a quarter 3. His average was a 88. Four of his test scores were 87, 94, 86, and 100. What was his last test score? ( statistics) ( please write down or type it out! ) ty
Answer:
The last test score should be 73
Step-by-step explanation:
[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]
Add all the values in the parentheses together to get:
[tex]88 = \frac{367 + X}{5}[/tex]
You want to remove the 5 next, so you multiply both sides by 5.
[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]
[tex]88 * 5 = 440[/tex]
You should get:
[tex]440 = 367 + x[/tex]
The last step is to subtract both sides by 367:
[tex]440 - 367 = 73[/tex]
[tex]X = 73[/tex]

Answer:
66°
Step-by-step explanation:
The applicable angle relations are ...
An exterior angle of a triangle is equal to the sum of the remote interior angles. Vertical angles are congruent.__
We recognize that angle HIJ, marked 105°, is an exterior angle to triangle DIJ. We also recognize that the angle marked x° is a vertical angle to angle DJI in triangle DIJ. Angles JDI, marked 39°, and DJI are remote interior angles with respect to angle HIJ.
We can use the relations described above to say that ...
∠HIJ = 39° +∠DJI
39° +x° = 105°
x° = 66° . . . . . . . subtract 39°
The measure of angle x is 66°.
Circle the correct option: A, B, C, or D.

Answer: 6 more games
Step-by-step explanation:
Let’s review what we know:
The red team’s probability of winning is 70% (0.7).The blue team’s probability of winning is 65% (0.65).There are a total of 120 games.
To find the amount of games each team will statistically win, we multiply the percentage by the number of games.
Red Team: 0.7 x 120 = 84 games.
Blue Team: 0.65 x 120 = 78 games.
84 - 78 = 6 games.
Therefore, the red team will statically win 6 more games than the blue team.

19. A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes. The number of blue leashes is 3 times the number of green leashes. How many blue leashes did she buy?
The number of the blue leashes will be 240.
What are linear equations?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
It is given that:-
A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.The number of the blue leashes will be calculated as:-
L = 320
B + P + g = 320
{ (320 x 0.3 ) } + 0.7 ( B + g ) = 320
( 96 ) + ( 2.8g ) = 320
2.8g = 320 / 96
g = 222 / 2.8 = 80
Now B = 3 x g
B = 3 x 80
B = 240
Therefore the number of the blue leashes will be 240.

After being exposed to an electromagnetic shrinking machine, Joe's height decreased by 120m over 4 seconds. His height decreased by the same amount each second.How much did Joe's height change each second?
-30m
20 m
-124 m
100 m
It is given that Joe was being exposed to an electromagnet shrinking machine. Because of this his height started decreasing .
Given,
The decrease was at a constant rate per second.
In 1.5sec, the height is decreased by 120cm.
So,
Variation per second =

What are the values of x and y ?
x = °
Because..
y = °
I solved this by:
Please help
Answer:
x = 35° and y = 72.5
Step-by-step explanation:
The value of x = 35° {because they are vertically opposite angles )
Now, the the value of y
=> y + y + 35° = 180° { sum of angles on a straight line is 180° }
=> 2y + 35 = 180°
=> 2y = 180 - 35
=> 2y = 145
=> y = 145/2
=> y = 72.5
Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.
Answer:
Unit Cubes = 125 in
Volume = 125 in
Step-by-step explanation:
To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.
Volume of rectangular prism = length x width x height
Advance explanation:
The formula to find the volume of the rectangular prism is this:
L x W x H = V
L = Length = 5 in
W = Width = 5 in
H = Height = 5 in
V = Volume = 125
You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In
Hope this helps!

Answer:
24 Units Cubed
Step-by-step explanation:
Start with the face of your 3D shape, which has a length/width of 3 units and a height of 4 units. Then look at the visible side of your figure, in this case it is the right side. You can see it's width/length of 2 units, so multiply 4x3x2, and in this case 4x3=12 and 12x2 is 24. making your answer 24 units cubed.
