Answer:
Kindly check explanation
Step-by-step explanation:
H0 : π ≥ 0.92
H1 : π < 0.92
At α = 0.05
Left tail
Z0.05/2 = Z0.025 = - 1.645
The test statistic
Zstatistic :
(m - p) / σ
Sample size, n = 85
m = 74/85 = 0.87
p = 0.92
σ = sqrt(p(1 - p) /n)
σ = sqrt(0.92(1 - 0.92) / 85)
σ = sqrt(0.0008658)
σ = 0.0294258
σ = 0.0294
Zstatistic :
(m - p) / σ
(0.87 - 0.92) / 0.0294
Zstatistic = −1.700680
Zstatistic = - 1.70
Decision region :
Reject H0: if ;
Zstatistic < Zcritical
-1.70 < - 1.645
Since,
Zstatistic < Zcritical ; then Reject H0.

Answer:
105
Step-by-step explanation:
A straight line is 180 degrees so 180-75=105
Answer:
x= 105 degrees
Step-by-step explanation:
We know that the sum of x and 75 degrees is equal to 180 degrees.
So that means that x= 180-75 or x=105 degrees
Pls help extra points and mark brainlist
5n+2k = 25k or 7n but u have to divide by 2
25k divided by 2 = 12.5
7n divided by 2 = 3.5
12.5 + 3.5 = 16 therefore the answer is 16

I don't really understand exponents well I was wondering if I could get some help on this plz
Ok so do 9 times itself 5 times so basically its this:
9*9*9*9*9
Next do the same but 3 times:
9*9*9
Exponents are not this:
9*3
But this:
9*9*9
Your answer:
59049/729
Another way to say it:
59049 over 729
There is your answer hope this helps
Answer:
9^2 (9 to the power of 2)
Step-by-step explanation:
Ok, this is how you find exponents:
Well, exponents are really just abbreviated multiplication, so to find the numerical value of 9^5 and 9^3, you need to multiply 9 by itself 5 times and 3 times, then divide.
9*9*9*9*9= 59049
9*9*9= 729
Then you divide: 59049/729= 81.
But the question asks to rewrite the answer using a single positive exponent, so now we simplify 81 into an exponent.
The square root of 81= 9
9*9=81
81 as an exponent= 9^2 (or 9 multiplied 2 times)
Another simple trick for solving exponents is to subtract the exponents:
9^5-9^3= 9^2 (5-3=2)
I hope this answer was helpful!

For this to work, whatever the white wax is, it needs to be 3 times as more as 5.
5x3=15
Answer:
i’ve done this before
Step-by-step explanation:
E and D
for every 12ml of red wax there’s 5 ml of white wax right? so you just multiply them at the same number to see if it matches.
12 x 5 = 60
5 x 5 = 25
12 x 3 = 36
5 x 3 = 15

Step-by-step explanation:
fair- sided coin is tossed 18 times . Which of the experimental outcomes is most consistent with theoretical outcomes
A) 4 heads and 14 tails
B) 6 heads and 12 tails
C) 9 heads and 9 tails
D) 10 heads and 8 tails
HELP WILL GIVE BRAINLY
Answer:
C) 9 heads and 9 tails
Step-by-step explanation:
if a fair sided coin is tossed, the probability of obtaining either heads or tails is 50%
If the coin is tossed 18 times, we would expect to see the same probability outcome which is 50% heads and 50% tails.
which corresponds to 9 heads and 9 tails.
Answer:
Step-by-step explanation:
Each throw is independent of any other throw. The probability of getting a head or tail is 1/2, so you should expect to flip as many heads as tails. Answer C shows that even split.

Which is the smallest standard deviation?
Answer:
C
Step-by-step explanation:
Because I'm smart.
x^2+6x+9=16 solve by completing the square
First move the 9 to the right side by subtracting 9 from both sides.
So we have x² + 6x ___ = 7 ___.
Notice that I created a space on each side of the equation.
The space is what we need to complete the square.
The number that goes in the spaces comes from half the coefficient of the
middle term squared, which in this case is half of 6, or 3, squared, which is 9.
So we add 9 to both sides of the equation.
Once we have completed the square, out trinomial will always factor as a binomial squared, and the number that goes inside the binomial will always be half the coefficient of the middle term of the trinomial.
So we have (x + 3)² = 16.
Now square root both sides to get x + 3 = ± 4
So x + 3 = 4 or x + 3 = -4.
Solving each equation from here, we get x = 1 or x = -7.
So our solution set is {1, -7}.

Answer:85
Step-by-step explanation:
Solve for the value of W
Answer:
8°
Step-by-step explanation:
5w + 1° + 7w - 7° + 90° = 180° { being linear pair }
12w = 180° - 84°
12w = 96°
w = 96° / 12
w = 8°
Hope it helps :)
Answer:
5w+1+90+7w-7=180(linear pair)
12w=180-84
w=96/12=8
y= -1/2

Answer:
(b) 60°
Step-by-step explanation:
The sum of angles in a pentagon is 540°, so you have ...
90° +90° +150° +x +150° = 540°
x = 540° -480°
x = 60°
