Answer:
Since, three fourth of \(t\) is \(15\). Hence, the required equation is \(\frac{3t}{4}=15\)
Step-by-step explanation:
For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944

Answer:
A
Explanation: horizontal line is 180 degrees, and the square means 90 degrees. So adding up the angles z + 90 + z =180
Answer:
not a solution
Step-by-step explanation:
Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.
7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20
Then p = - 2 is not a solution of the equation
