Answer:
The answer to your question is: 21
Step-by-step explanation:
Data
AB = BC = CD
BQ = 21
QD = ?
PC = 11
Process
Here there are 2 triangles
ΔQCB and ΔQCD
These triangles share one side QC
And one side measures the same BC = CD
And the ∠ BCQ = ∠ DCQ
Then these triangles are congruents SAS
if QB = 21 then QD = 21
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean
Step-by-step explanation:
In the figure attached, the distribution of data is shown.
From the picture we can see that:
- The data has a standard deviation of 0.15 (= 0.5 - 0.35 = 0.65 - 0.5)
- The mean of the data is 0.5
- A value of 0.7 is more than 1 standard deviation of the mean.
- A value of 0.9 is more than 2 standard deviations from the mean (0.8 is 2 standard deviations from the mean)

Answer:
y = 2x +13
Step-by-step explanation:
1. find the slope by using the formula y2-y1
--------
x2-x1
which is
23 - 19 4
------------ = --- = 2
5-3 2
2. finding the y intercept
so to find the y intercept you plug in the numbers to this formula
y-y1 = m (x-x1)
y - 19 = 2 (x -3)
y - 19 = 2x -6
+19 +19
y = 2x +13
