Answer:

0.0009

Step-by-step explanation:

\mu=4

\sigma=0.55

n = 8

This is the left tailed test .

The null and alternative hypothesis is ,

H_0:\mu=4

Ha:\mu

Test statistic = z=-3.12            from the table.

P(z <-3.12 ) = 0.0009

P-value =0.0009

What is the area of an equilateral triangle that has 2 yards and a height of 4.25 ft?
RUDIKE [14]
The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation. 6*4.25=25.5 then divide by two. 25.5/2=12.75So the area of the triangle is 12.75 ft^2Hope this helps
