Answer:
1. x = 20
2. x = 3
3. RST = 22 degrees
Step-by-step explanation:
1. Since QR bisects PQS, the measure of the angles PQR and PQS should be equal, so we can set their expressions equal to each other, and then solve.
4x-10 = -3x+130
4x = -3x +140
7x = 140
x = 20
2. Since there is a CAB has a right angle, the measure of angles CAD and BAD should add up to 90 degrees. So we can set the sum of their expressions equal to 90 degrees.
(5x+57) + (x+15) = 90
6x + 72 = 90
6x = 18
x = 3
3. I can't see where the R is but if it is on the empty line then we can find RST by subtracting the measure of angle TSU from angle RSU.
TSU - RSU = RST
91 - 69 = 22 degrees
RST = 22 degrees
Answer:
(x+1)(x+7)
Step-by-step explanation:
F(x) = a.x . We ha to calculate a.
Back to the table, let's rewrite the coordinates
A(0,0)
B(2,-1)
C(4,-2)
D(7,-3.5)
We know that constant is called slope or coefficient is equal to:
a=y/x
Apart from A, in each of the coordinates y/x =-1/2 & this is the slope of the equation f(x) = (-1/2)x
Answer:
99
Step-by-step explanation:
P(3) = 1-0.88 = 0.12
P(3 or 4) = 0.12 + 0.21 = 0.33
Expected no. = no
= 300(0.33) = 99
Answer:
Step-by-step explanation:
Basically, if you want to find the probability of getting either outcomes, you will need to subtract the probability of getting neither outcomes in the question. The probability for both outcomes are 7/9 and 5/9 respectively. You will have to multiply to get the probability of getting both of the non-desired outcomes. Hence, it gives the equation above
