Answer:
1.28
Step-by-step explanation:
bec. it is
The critical z-value is 1.2816 (left-tailed value) and critical z value is -1.2816 (right-tailed value)
What is z-value?A z-score is the number of standard deviations from the mean value of the reference population.
Given that, α = 0.90,
Since α = 0.90, the area under the curve is 1 - α → 1 - 0.90 = 0.1
For right-tailed value = -1.2816
For left-tailed value = 1.2816
Hence, The critical z-value is 1.2816 (left-tailed value) and critical z value is -1.2816 (right-tailed value)

The incomplete table below summarizes the number of left-handed students and right-handed students by gender for the eighth-grade students at Keisel Middle School. There are 5 times as many right-handed female students as there are left-handed female students, and there are 9 times as many right-handed male students as there are left-handed male students. if there is a total of 18 left-handed students and 122 right-handed students in the school, which of the following is closest to the probability that a right-handed student selected at random is female? (Note: Assume that none of the eighth-grade students are both right-handed and left-handed.)
A) 0.410
B) 0.357
C) 0.333
D) 0.250
Answer: A) 0.410
In order to solve this problem, you should create two equations using two variables (x and y) and the information you're given. Let x be the number of left-handed female students and let y be the number of left-handed male students. Using the information given in the problem, the number of right-handed female students will be 5x and the number of right-handed male students will be 9y. Since the total number of left-handed students is 18 and the total number of right-handed students is 122, the system of equations below must be true:
x+y=18
5x+9y=122
Biologists discovered an invasive species of fish in a lake. The function fff models the population size (in thousands of fish) for this species as a function of time (in months) after being discovered.
Plot the point on the graph of fff that corresponds to the time when the population reached its maximum size.
Answer: (4,9) which is the vertex or the top of the parabola
Step-by-step explanation:
The population drops after 4 months making that the maximum of the population of the fish. The answer is the vertex of the parabol which is basically the top of the peak

Sam’s gross income is $1800 every other Friday. Calculate his net income, for one paycheck, if his Federal tax rate is 10% and his State tax rate is 3%.
Answer:
I believe the answer is $1571.4
Step-by-step explanation:
1800 - 10% = 1620
1620 - 3% = 1571.4
The net income of Sam will be $ 1571.4.
It is given that Sam's gross income is $1800 every other Friday. He has to pay two taxes i.e., 10 % federal tax rate and 3% state tax rate.
We have to calculate his net income.
What is the value of 18 % of 300 ?
The value will be 54.
As per the question Sam's gross income is $1800 , every other Friday.
He has to pay some Federal tax rate , so 10 % will be deducted from gross income.
⇒ 1800 - 10% = $ 1620
Now , he has to pay some State tax rate , so 3 % will be deducted from gross income.
⇒ 1620 - 3% = 1571.4
Thus , his net income will be $ 1571.4.

Answer:
SA =12.
Step-by-step explanation:
In a parallelogram the diagonals bisect each other , so:
2x - 1 = x + 7
2x - x = 7 + 1
x = 8.
QS = x + 4 = 8 + 4
= 12.
But QS = SA, so SA =12.

Find the amount of degrees in x, if the three angles of a triangle are 2x, 2x, and 32 degrees.
Answer: 2x=74
Step-by-step explanation:
Every triangle is 180 degrees.
so you will take 180-32= 148
then with that you will add up the x's and there are 4...
so then you will take 148/4 and get the answer of...
148/4=37
x=37
but it asked for 2x
37*2
2x=74
final answer is 74
Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)
Answer:
a + (b + c) = (a + b) + c
Step-by-step explanation:
a= (-12), b = 4, c = (-25)
[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]
Answer:
GIVEN :-
a = -12b = 4c = -25TO VERIFY :-
a + (b + c) = (a + b) + cSOLUTION :-
Find the values of L.H.S. & R.H.S.
L.H.S. :-
Put all values in → [tex]\boxed{a+(b+c)}[/tex]
⇒ -12 + [4 + (-25)]
⇒ -12 + (4 - 25)
⇒ -12 + (-21)
⇒ -12 - 21
⇒ -33
R.H.S. :-
Put all values in → [tex]\boxed{(a+b)+c}[/tex]
⇒ (-12 + 4) + (-25)
⇒ -8 - 25
⇒ -33
CONCLUSION :-
L.H.S. = R.H.S.
⇒ a + (b + c) = (a + b) + c
You deposit $3500 in a savings account that has a rate of 6% compounded semiannually. How much is in the account after 3 years?
Answer:
$4,179
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Total deposit (P)= $3,500
rate of interest = 6%
Rate of interest (semiannual) (r) = 3%
Time = 3 years
Time period (t) (semiannual) = 6
So, we can calculate the total amount after 3 years by using following formula,
FV = P [tex](1+r)^{t}[/tex]
By putting the value, we get
FV = $3,500 ( 1 + 0.03)^6
FV = $3,500 ( 1.03)^6
= $3,500 × 1.194
= $4,179
