Houa has an action figure collection. She keeps some in a display case and the rest on
the wall. 82 of her action figures are on the wall, and 59% of her action figures are in the display case. What is the total number of action figures in Houa's collection?
Answer:
200 action figures
Step-by-step explanation:
Given
[tex]Wall = 82[/tex]
[tex]Display\ Case = 59\%[/tex]
Required
Total action films
If 59% is on a display case, then 4!% is on the wall. Let the total be x.
So, we have:
[tex]Wall = 41\% * x[/tex]
Substitute 82 for Wall
[tex]82= 41\% * x[/tex]
[tex]82= 0.41 * x[/tex]
[tex]200= x[/tex]
[tex]x = 200[/tex]

Step-by-step explanation:
What are the coordinates of the midpoint between the points (-1,4) and (2,-5)
Answer:
(1/2, -1/2)
Step-by-step explanation:
To find a midpoint add the two x's and divide by 2 so -1+2 / 2 = 1/2
add the two y's and divide by 2 so 4-5 / 2 = -1/2
Put the two numbers together as a coordinate (1/2, -1/2)

Step-by-step explanation:
To assess the effectiveness of a kindergarten-readiness program, 15 children from a random sample were each given a diagnostic assessment before beginning the program and a follow-up assessment after completing the program. For each child, the difference in the score points between the two assessments was calculated and used to create the 95 percent confidence interval (20.1,23.9)(20.1,23.9).
Assuming all conditions for inference are met, which of the following is a correct interpretation of the interval?
A) For all children in the program, 95 percent of the children will have a mean difference in scores of between 20.1 points and 23.9 points.
B) There is a 0.95 probability that the mean difference in scores for all children in the sample is between 20.1 points and 23.9 points.
C) There is a 0.95 probability that the mean difference in scores for the children in the program is between 20.1 points and 23.9 points.
D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.
E) We are 95 percent confident that the mean difference in scores for the children in the sample is between 20.1 points and 23.9 points.
Answer:
D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95 percent confidence interval (20.1,23.9)
We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.
Need help please. What is the area of the shaded region. Thank you so much.
Answer:
[tex]Area = 8\ unit^2[/tex]
Step-by-step explanation:
Given
The 7 * 3 grid
Required
Determine the area of the shaded
From the grid, 4 cells on 2 rows were shaded.
Since 1 grid cell = 1 unit.
The area is:
[tex]Area = 4\ unit * 2\ unit[/tex]
[tex]Area = 8\ unit^2[/tex]
What is the equation ( y = mx + b) of the line that passes through (2,5) and (6, 13)
Answer:
y=2x+1
Step-by-step explanation:
y=mx+b
m=(13-5)/(6-2)
m=8/4
m=2
b=y-mx
b=5-2*2
b=5-4
b=1
y=2x+1
Answer:
y=2x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(13-5)/(6-2)
m=8/4
m=2
y-y1=m(x-x1)
y-5=2(x-2)
y-5=2x-4
y=2x-4+5
y=2x+1

I need help with this
Answer:
x=45
Step-by-step explanation:
This is a triangle so it interior degrees will add up to 180.
W
Since Line AC is tangent to Circle O at point c, Point C measures 90 degrees.
We can find OAC by using the triangle interior theorem,
[tex]45 + 90 + x = 180[/tex]
[tex]135 + x = 180[/tex]
[tex]x = 45[/tex]

Answer:i know the x for 1 not for the other 2
Step-by-step explanation:1 is 4
Answer:
17) x= 36
18)
Step-by-step explanation:
17) 2x + 2x + x =180°(angles of a triangle)
5x = 180°
divide both sides by 5
X = 36
18) 7x +3x + 90° = 180°(angles of a triangle)
10x = 90
X = 9
19) 2x + x + x = 180° (angles of a triangle)
4x = 180°
X = 45

A fish is swimming at a constant rate toward the ocean floor. The equation
y = -7x -3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Which statement best describes the depth of this fish, given this equation? (DOK 3)
A
From a starting position of 3 meters below sea level, the fish is going down( descending) 7 meters per second
B
From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second
C
From a starting position of 7 meters below sea level, the fish is descending 3 meters per second
D
From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second
Answer:
A
Step-by-step explanation: the -7x represents the 7 meters the fish is going down every second and the -3 would be the fish starting at 3 meter below sea level
