What are the coordinates of the x and y intercepts of the equation 3x+2y=12
Sonbull [250]
To find the x-intercept you must make y=0

3x+2y=12 - substitute 0 for y
3x+2(0)=12 - multiply 2 and 0
3x+0=12 - add zero
3x=12 - divide by 3
x=4

To find the y-intercept you must make x=0

3x+2y=12 - substitute 0 for x
3(0)+2y=12 - multiply 3 and 0
0+2y=12 - add 0 and 2y
2y=12 - divide by 2
y=6

The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and
wariber [46]

Answer:

E 0.923

Step-by-step explanation:

The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:

z=\frac{x-\mu}{\sigma}, Where μ is the mean, σ is the standard deviation and x is the value.

Given that:

σ = 7, μ = 80 and x = 90  

z=\frac{x-\mu}{\sigma}=\frac{90-80}{7} =1.43

From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
