Answer:
(8,10) is not a solution
Step-by-step explanation:
Cuz it’s not on both inequality shaded part but just one of them and also when we substitute one is true and the other one is false
2x + y _< 8
2(8) + 10 _< 8
18 + 10 _< 8
28 _< 8 false
X + y _> 4
8 + 10 -> 4
18 _> 4 true
Answer:
33) $8440
34) $67,964.62
Step-by-step explanation:
33) The interest on 1 for 270 days is ...
... I = Prt = 1×0.09×(270/360) = 0.0675
so the proceeds from a loan with a face value of 1 will be
... 1 - 0.0675 = 0.9325
We want to find the face value of a loan with proceeds of $7870.30, so we need to solve the equation ...
... $7870.30 = P×0.9325
... P = $7870.30/0.9325 = $8440
34) The discount is computed from ...
... I = Prt = 70,000×0.063×(24/52) ≈ 2035.38
Then the amount Smith will pay for the T-bill is ...
... $70,000 -2035.38 = $67,964.62
Answer:

a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100



Formula of test statistic =
=
=
refer the z table for p value
p value = 0.8849

p value of part B is less than Part A because part B have 10 times the number the tosses.
Answer:
A is correct.
Step-by-step explanation:
Let's use the variables m and v for this:
4m + 3v = 140
v = 2m
Insert this variable:
4m + 3(2m) = 140
4m + 6m = 140
10m = 140
m = 14
One movie costs 4 dollars:
14*4 = 56
He spent $56 on movies
