Answer:
It's 14 pts total.
Step-by-step explanation:
He started out with 8. Then he answered 3 more questions that were 2 pts each. If you do 3x2, that would =6. Add 6 and 8, and you get 14!
To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7
-2x + (1/2)y = 18
(1/2)y = 2x + 18
y/2 = 2x + 18
y = 2*(2x + 18)
y = 2*2x + 2*18
y = 4x + 36
The x intercept is the value of x, when the y value is 0.
0 = 4x + 36
0 - 4x = 36
-4x = 36
x = 36/-4
x = -9
The x intercept is -9
I hope this helps.
Answer:
5. 4 6. 6
Step-by-step explanation:
Number 5
Subtract the numbers: 10 - 6 = 4
Number 6
![70-\left(\sqrt[3]{64}\right)^3](https://tex.z-dn.net/?f=70-%5Cleft%28%5Csqrt%5B3%5D%7B64%7D%5Cright%29%5E3)
![\left(\sqrt[3]{64}\right)^3=64](https://tex.z-dn.net/?f=%5Cleft%28%5Csqrt%5B3%5D%7B64%7D%5Cright%29%5E3%3D64)
Subtract the numbers: 70 - 64 = 6
