Answer:
0.2278
Step-by-step explanation:
z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation
z => 72 - 80/4
= -2
Probability value from Z-Table:
P(x ≤ 72) = P(x = 72) => P(x < 72)
0.02275
Approximately =>0.2278
The probability of the calculated value is " 0.0227501", its calculation can be defined as follows:
Normal distribution calculation:Mean [tex](\mu)= 80\\\\[/tex]
Standard Deviation [tex](\sigma)= 4[/tex]
Since we know that
[tex]\to Z_{\text{score}} =\frac{x-\mu}{\sigma} \\\\[/tex]
a)[tex]x = 72[/tex]
[tex]\to \frac{72-80}{4}=\frac{-8}{4}= -2[/tex]
so,
[tex]P(x < 72) = P(z < -2) =0.0227501[/tex]
PS: you have to refer z score table to find the final probabilities.

find the difference in altitude between a mountain that has an altitude of 4878 feet and a desert valley that is 428 feet below sea level.
Answer:
4450 I think
Step-by-step explanation:
4878-428=4450
The difference in altitude and desert valley is 53.06 feet.
What is Integer?Integers come in three types:
Zero (0)Positive Integers (Natural numbers)Negative Integers (Additive inverse of Natural Numbers)Given:
The desert valley that is 428 feet below sea level is (-428).
and, altitude of 4878 feet is (+4878) feet.
So, the difference is
= 4878 - (428)
= 4878 + 428
= 5306 feet
Hence, the difference is 5306 feet

If the two variables in a given theory move in the same direction, which type of relationship do they share?
A negative
B. positive
C. neutral
D.l inverse
Using proportionality of variables, it is found that they are classified as positive, hence option B is correct.
What is the proportionality of variables?When two variables move in the same direction, their relation is called direct or positive.When two variables move in the different directions, their relation is called inverse or negative.If they are independent, they are neutral.In this problem, they move in the same direction, thus they are classified as positive and option B is correct.

Answer: 3,4,5,6 can be the complete list for the f(x).
Step-by-step explanation:
Given a polynomial function f(x) which is a fourth degree polynomial .Therefore it must has 4 roots.
Let's check all the options for the possible list of roots of f(x)
1) 3,4,5,6 can be the complete list for the f(x) .
Option 2) and option 3) cannot be the complete list for the f(x) as it has one complex root and complex roots occur in pair.
Option 4) cannot be the complete list for f(x) as complex roots occur in pair and they conjugates but conjugate of 5+i is 5-i(which is not given) not -5+i

Please help me, I don’t know how to solve for x on this one
Use trigonometry to solve for x.
The tangent function is defined to be opposite side divided by the adjacent side.
tan(78) = x/10
tan(78)(10) = x
47.0463010948 = x
We now round off to two decimal places. In other words, we round off to the nearest tenths.
47.05 = x

1/4x-3/4=7/x solving the following rational equation for x
Answer:
x¹= -4 , x²= 7
Step-by-step explanation:
1) Determine the defined range
¼x-¾=7/x =/ 0
2) Move the expression to the left-hand side and change its sign
[tex] \frac{1}{4} x - \frac{3}{4} - \frac{7}{x} = 0 \\ \\ [/tex]
3) Write all numerators above the least common denominator 4x
[tex] \frac{ {x}^{2} - 3x - 28 }{4x} = 0[/tex]
4) When the quotient of expressions equals 0, the numerator has to be 0
x²-3x-28=0
5) Write -3x as a difference
x²+4x-7x-28=0
6) Factor out x from the expression
x(x+4)-7x-28=0
7) Factor out -7 from the expression
×(x+4)-7(x+4)=0
8) Factor out x+4 from the expression
(x+4)×(x-7)=0
9) When the product of the factors equals 0, at least one factor is 0
x+4=0
x-7=0
10) Solve for the x
x+4=0 -> x= -4
x-7=0 -> x=7
11) Check if the solution has defined range
x= -4
x=7
12) The solution has 2 solutions
[tex]x1 = - 4 \: \: x2 = 7[/tex]
Answer:
The correct answer is -9
