Answer:
4. alternate exterior angles
5. 4.5
Answer:
52.5
Step-by-step explanation:
Since ED ≈ AD, ∆AED is a isosceles triangle where <EAD and <AED has same angle measurement
Now, m<B = 105°, since ABCD is a parallelogram, <B = <D
so, m<ADC = 105° so, m<ADE = 180°-105° = 75°
Now, m<EAD+m<AED+m<ADE = 180°
or, m<AED+m<AED+m<ADE = 180°
or, x+x+75°=180°
or, 2x=180+75°
or, 2x=105°
or, x=52.5°
-5x - 25 = 78
-5x = 78 + 25
-5x = 103
x = 103/-5
x = -20.6
Compare her solution with that above.
Let BS be the event that the patient survives bypass surgery.
Let H be the event that the heart damage will heal.
Then P(BS) = 0.60, and also we have a conditional probability: GIVEN that the patient survives,
the probability that the heart damage will heal is 0.5, that is P(H|BS) = 0.5
We want to know P(BS and H).
Using the formula of the conditional probability:
P(H and BS) = P(H|BS)·P(BS) = (0.6)(0.5) = 0.3
Answer:
It's A.
Step-by-step explanation:
an = 4.2^n
When n = 1, a1 = 4 . 2 = 8.
When n = 2, a2 = 4 . 2^2 = 16
When n = 3, a3 = 4 . 2^3 = 32
and a4 = 64.
