What formula to use for determining the probability that the mean stress level for a sample of 70 employees will fall above 52? (mean =50; STD 10)
Answer:
0.4207
Step-by-step explanation:
Determine z-score
[tex]z=\frac{\bar{x}-\mu}{\sigma/\sqrt{n}}\\ \\z=\frac{52-50}{10/\sqrt{70}}\\ \\z\approx1.6733[/tex]
Find P(Z>1.6733)
[tex]P(Z > 1.6733)=normalcdf(1.6733,\infty)\approx0.4207[/tex]
Therefore, the probability that the mean stress level for a sample of 70 employees will fall above 52 is 0.4207

Please help 50 points: A ball is thrown straight up, from 3 m above the ground, with a velocity of 14m/s. When does it hit the ground? Use vertical motion formula.
Answer:
3.058s
Step-by-step explanation:
i cant rewrite everything i solve in the paper sorry
Step-by-step explanation:
In this question, to find the total height first, we must also take into consideration the acceleration due to gravity as well. To find the distance by which acceleration due to gravity pulls the ball down must know the Initial velocity.
In the answer key, it says that gravity changes the ball's height by a distance of -5t^2
Is initial velocity in this question 0 or 14m/s? Because if it is 14, then gravity should change the balls position by -(14+5t^2), not -5t^2, because if I remember correctly, the formula for finding distance is vt(initial velocity)+(1/2)at^2 ,and not just (1/2)at^2

Can you help me please
Step-by-step explanation:
4/5x-3=3/10x+7
We move all terms to the left:
4/5x-3-(3/10x+7)=0
Domain of the equation: 5x!=0
x!=0/5
x!=0
x∈R
Domain of the equation: 10x+7)!=0
x∈R
We get rid of parentheses
4/5x-3/10x-7-3=0
We calculate fractions
40x/50x^2+(-15x)/50x^2-7-3=0
We add all the numbers together, and all the variables
40x/50x^2+(-15x)/50x^2-10=0
We multiply all the terms by the denominator
40x+(-15x)-10*50x^2=0
Wy multiply elements
-500x^2+40x+(-15x)=0
We get rid of parentheses
-500x^2+40x-15x=0
We add all the numbers together, and all the variables
-500x^2+25x=0
a = -500; b = 25; c = 0;
Δ = b2-4ac
Δ = 252-4·(-500)·0
Δ = 625
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ−−√=625−−−√=25
x1=−b−Δ√2a=−(25)−252∗−500=−50−1000=1/20
x2=−b+Δ√2a=−(25)+252∗−500=0−1000=0

Answer:
116
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360 degrees, so:
79+55+110+x=360
244+x=360
x=116
Hii I really need help determining the y intercept of the line.
So what's they?
X intercept is the co-ordinate where the line crosses x axis ,
Y intercept is the co-ordinate where the line crosses y axis
So
X intercept (-10,0)Y intercept (0,-45)sale price: $66.30 percent of discount: 65%
find the regular price
Answer:
$189.43
Step-by-step explanation:
P = regular price
65% as a decimal = [tex]\frac{65}{100}[/tex] = .65
Discount = .65
To get the amount of the discount we would multiply P * .65
To find the sale price we subtract the discount from the original price.
Now we write our equation:
P - P(.65) = $66.30
Solve for P
P - P(.65) = $66.30
1P - P(.65) = $66.30
1P - .65P = $66.30
.35P = 66.30 Divide each side by .35
.35P.35 = 66.30/.35
P = 66.30/.35
P ≈ $189.43

1 part = 1/3
1/3 + 1/3 + 1/3 = 1
Answer:
1/3
Step-by-step explanation:
because all the sides and shapes are equal it would be 1/3as well as
1/3 + 1/3 +1/3=1

Answer:
a) x=-a, x=a+b
b) x=5/2a, x=1/3b
c) x=1/2a, x=a/a-2
Step-by-step explanation:
a) (x-a)(x-a)-b(x+a)=0
(x+a)(x-a-b)=0
x=-a, x=a+b
b) 3x(2x-5a)-b(2x-5a)=0
(2x-5a)(3x-b)=0
x=5/2a, x=1/3b
c) (2a-4)x^2=a^2(x-1)
(2x-a)(ax-2x-a)=0

Answer:
50° for angle FEG
Step-by-step explanation:
Following the Verticle Angles Theorem, the angle on the other side of 140 must also be 140. Since it is split up and we know one of them is a right angle, we must subtract 90 from 140.
140 - 90 = 50.
Thus, angle FEG is 50°.

What is the average rate of change of the function in the table at the interval x = -1 to x = 1?
Answer:
the answer is undefined
Step-by-step explanation:
If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

Find f(3) and interpret its meaning.
Answer:
f(3) = 425
f(3) is the elevation of a mountain climber after 3 hours of climbing.
Step-by-step explanation:
So we are given a line that relates time to elevation. We are also given that the equation of the line is f(x) = 125x + 50. From looking at the graph given, we can see that x is the time, in hours, and y, or f(x), is the height, in feet. We are asked to find f(3) and interpret it's meaning.
To find f(3), we would have to find what f(x) is when x = 3. To do this, lets plug in 3 for x into the given equation:
f(3) = 125(3) + 50 = 425
So f(3) = 425. Now, we already know that x is the time in hours and y, or f(x), is the elevation in feet. We set x to 3 when solving for f(3). We have also found that f(3), or y when x = 3, is 425. So f(3), or 425, is the elevation after 3 hours.
I hope you find my answer and explanation to be helpful. Happy studying.
