A population of values has a normal distribution with μ=152.8 and σ=26.2 . You intend to draw a random sample of size n=94 .
Find the probability that a single randomly selected value is less than 149.6.
P(X < 149.6) =
Answer:
P = 0.022
Step-by-step explanation:
Draw a normal distribution curve
Find the z score.
z score = 0.12
Find the probability for the z score.
P = 0.478
Subtract probability from 0.5
0.5 - 0.478 =0.022

Find the equation of the linear function represented by the table below in slope intercept form.
Step-by-step explanation:
let equation be y = mx + b.
m = (9-5)/(3-1) = 2
sub (1, 5):
5 = 2(1) + b
b = 3
therefore the equation: y = 2x + 3

Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise the plan will not apply. How much interest will she gain after maturity of the plan
Answer:
14,400.00
You're going to take 40,000 multiplied by 7.2 which gives you the interest for one year. Multiply that by 5 to get through interest for 5 years.
The amount of interest that she gained after the maturity of the plan will be ₱14,400.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
I = (PRT)/100
Where I is the interest, P is the principal, R is the rate of interest, and T is the time.
Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise, the plan will not apply.
Then the amount of interest that she gained after the maturity of the plan will be
I = (40,000 x 7.2 x 5) / 100
I = 400 x 7.2 x 5
I = ₱14,400
The amount of interest that she gained after the maturity of the plan will be ₱14,400.

Would you please help me on this question?
Answer:
x = 2
Step-by-step explanation:
Given that the measure of segment BC must equal the addition of the measure of segment BA plus the measure of segment AC, we can write this in equation form:
BC = BA + AC
then we replace them with the measure information they provide:
12 x + 4 = 7 x - 4 + 8 x + 2
and we solve for x in the equation:
12 x + 4 = 15 x - 2
subtract 12 x from both sides:
4 = 15 x - 12 x - 2
4 = 3 x - 2
add 2 on both sides
4 + 2 = 3 x
6 = 3 x
x = 6/3
x = 2
What is the slope please help
Please explain how you got the answer if you can
What is the slope of the line shown below?
Answer: The slope of the line can be determined from the gradient equation, rise (y axis)/ run (x-axis)
Hence let (-1, 8) be A and (2, -4) be B. The slope from A to B is (-4-8)/(2-(-1))= (-12)/3= -4
Hence the gradient/ slope of the line is -4.

Which ordered pairs (x,y) are solutions to the linear equation 2x+3y=6
2,3
0,2
3,0
3, -2
6,-2
0,6
Answer:
I think it is 0,2
Step-by-step explanation:
Because you need to substitute the ordered pairs into the linear equation:
so,
2(0)+3(2) = 6
6=6
The two side, so equation are identical, so the correct answer is (0,2).

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:

At the end of a snow storm, Riley saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Riley's lawn, in inches, can be modeled by the equation S = 13 – t, where t is the time, in hours, after the snow stopped falling. What is the x-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
The x-intercept of the function is 13 which represents the number of hours until all the snow has melted.
Step-by-step explanation:
Since there were 0 inches of snow on the lawn after 13 hours, the x-intercept of 13 represents the number of hours after the storm stopped when all of the snow had melted away.

the 200th term of the arithmetic progression 10 97,94,91,.............is
Answer:
-500
Step-by-step explanation:
Given sequence;
97, 94, 91 ......
Unknown;
The 200th term of the sequence;
Solution:
Since we were given an arithmetic progression, we need to first find the common difference;
Common difference = second term - first term
= 94 - 97
= -3
To find the 200th term, we use the expression below;
Sn = a + (n-1)d
a is the first term
n is the nth term
d is the common difference
S₂₀₀ = 97 + (200 - 1 ) x -3 = -500
