According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard deviation of 0.07 inches. What is the probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days (taken over many years)?
Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Answer:
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = 0.4404
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 0.10 inches
Given that the standard deviation of the population = 0.07inches
Let 'X' be a random variable in a normal distribution
[tex]Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428[/tex]
Step(ii):-
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = P(Z≤0.1428)
= 1-P(Z≥0.1428)
= 1 - ( 0.5 +A(0.1428)
= 0.5 - A(0.1428)
= 0.5 -0.0596
= 0.4404
Final answer:-
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = 0.4404
Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.
P(-8,-8),q ( 0,0)
Answer:
y = x
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-8 - 0) / (-8 - 0)
-8 / -8
= 1
So, the slope is 1.
Plug in the slope and a point into y = mx + b and solve for b:
y = mx + b
-8 = 1(-8) + b
-8 = -8 + b
0 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = 1x + 0
y = x
So, the equation of the line is y = x

Answer:
The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
Answer:
The following angles are 45 degrees: SPT, QPT, PQT, RQT, QRT, SRT, RST, PST.
The following angles are 90 degrees: STP, PTQ, QTR, RTS
Step-by-step explanation:
Notice that it is a square. Since it is a square, any diagonal line drawn from a corner to the opposite corner will bisect the angle at both corners. Since in a square each angle at each corner is 90 degrees, we know that the angles listed above are 45 degrees.
There are multiple ways to arrive at the conclusion that angles STP, PTQ, QTR, RTS are all 90 degrees. The easiest way to arrive at that answer is looking at each triangle. Notice how the square is divided into 4 triangles. Each triangle contains two 45 degree angles. Since the internal angles of each triangle must sum to 180 degrees, this means the last angle is 90 degrees.

Find the solution to the equation algebraically. Check your answer. k - 16 = 4
Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
Hope this helps!
Hey there!
k - 16 = 4
ADD 16 to BOTH SIDES
k - 16 + 16 = 4 + 16
CANCEL out: -16 + 16 because it give you 1
KEEP: 4 + 16 because it give you the x-value
NEW EQUATION:
k = 4 + 16
k = 16 + 4
SIMPLIFY IT!
k = 20
Therefore, your answer is: k = 20
Good luck on your assignment & enjoy your day!

Step-by-step explanation:
24*0.8 = $19.20
Answer:
Step-by-step explanation:
The discount is:
price × discount
We can substitute the discount of 20% for 0.2 and multiply to find the amount of money taken away which gives us the remaining amount or the amount you pay.

Write x² - 6x + 3 in the form (x-a)²+ b.
Answer:
(x + 3)² - 12
Step-by-step explanation:
x²+6x-3
= x²+ 6x + 9 - 12
= (x + 3)² - 12
The form of x² - 6x + 3 can be written as (x-3)² - 6.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
Equation= x² - 6x + 3
Now,
To write x² - 6x + 3 in the form (x-a)²+ b, we can use the method of completing the square. This involves adding and subtracting a constant term to make the expression a perfect square trinomial. Here are the steps:
Write x² - 6x + 3 as x² - 6x + ___ - ___ + 3, leaving two blanks for the constant term.
To find the constant term, divide the coefficient of x by 2 and square it. In this case, -6/2 = -3 and (-3)² = 9. So we fill in the blanks with 9 and get x² - 6x + 9 - 9 + 3.
Factor the first three terms as a perfect square: (x - 3)² - 9 + 3.
Simplify the last two terms: (x - 3)² - 6.
Compare with the form (x-a)²+ b and identify a and b. In this case, a = 3 and b = -6.
Therefore, by the given equation the answer will be (x-3)² - 6.

percent of 45.
Answer:
20%
Step-by-step explanation:
When asked, "x is what percent of y?" divide x by y and multiply by 100.
9/45 = 0.2
0.2 * 100 = 20%
Recall that we multiply by 100 to convert decimal to percent.
Step-by-step explanation:
Let x% of 45 be 9 Then
x % of 45 = 9
x / 100 * 45 = 9
45x = 900
x = 900 / 45
x = 20%
