Do u mean from the book or something?
17/29, 14/29, 9/29, 8/9
Hope this helps
Answer:
The scores are between 50 and 90
Step-by-step explanation:
When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e
μ ± 2σ
Hence,
mean of 70 and a standard deviation of 10
μ ± 2σ
μ - 2σ
70 - (2 × 10)
= 70 - 20
= 50
μ + 2σ
= 70 + (2 × 10)
= 70 + 20
= 90
Answer:
1/2
Step-by-step explanation:
y = mx + b is slope intercept form.
b = y intercept. where the line first passes through on the y axis
that number is 3.
y = mx + 3.
to find M (slope) you have to do RISE / RUN.
Run is going left or right from a point
Rise is going up or down from a point.
To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.
From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.
So, the slope is 1/2.
3 over 20 is the fraction in simplest form.
