Suppose a normal distribution has a mean or 70 and a standard deviation of 7. What is P(x>=94)? O A. 0.075 O 8. 0.025 c. 0.84 OD 0,16
Answer:
0.025
Step-by-step explanation:
Mean = 79 ; Standard deviation = 7
P(x ≥ 93)
We obtain the ZSCORE :
Zscore = (x - mean) / standard deviation
x = 93
Zscore = (93 - 79) / 7 = 2
P(Z ≥ 2) = 0.02275

a water main is to be constructed with a 10% grade in the north direction and a 20% grade in the east direction. determine the angle theta required in the water main for the turn from north to east
Answer:
26.6degrees
Step-by-step explanation:
Given
percent grade through north = 10% (opposite)
percent grade through east = 20% (adjacent)
Get the direction
Using the SOH CAH TOA identity
tan theta = opp/adj
tan theta = 10/20
tan theta = 0.5
theta = arctan (0.5)
theta = 26.6degrees
Hence the required angle is 26.6degrees
Which function, g or h, is the inverse function for function ƒ?
Answer:
B.
Step-by-step explanation:
Remember that graphically, a function and its inverse are reflections over the line y = x.
Given the graph of f, we see that h is not a reflection over the line y = x. So, we can eliminate choices A and C.
Function g is indeed a reflection of y over the line y = x. A function and its inverse is not its reflection over the x-axis so D is incorrect.
Hence, our answer is B.
Answer:
The answer is B. " the function g because the graphs of ƒ and g are symmetrical about the line y = x"
You are going to a 1940 mile trip, and your car get about 28 miles per gallon. Gas prices along your route average $2.95 per gallons. Calculate the cost of the trip

The length of a rectangle is 4 inches more than its width, and its perimeter is 34 inches. Find the length and width of the rectangle. If w= the width of the rectangle, then the length equals OW-4 OW-4 401
Answer: L = 4 + w
A = 2P - 4
lw = 2(2l +2w) - 4
lw = 4(l + w) - 4
(w+4)w = 4 ( w+4+w) -4
(w +4)w = 4(2w + 4) - 4
w^2 + 4w = 8w + 16 - 4
w^2 + 4w = 8w + 12
w^2 - 4w - 12 = 0
( w - 6 )( w + 2 ) = 0
w - 6 = 0 ----> w = 6 ----> L=10 ---> P = 32 and A = 60
w + 2 = 0 ---> w = -2 <--- width cannot be negative; disqualified/rejected

You can use any of several other strategies, including finding the slope and y-intercept, then rearranging the equation.
Another strategy that works is to try the answer choices. You might notice that the first given point works in the first equation, so it may make sense to try the second given point in each equation.
The above version of the equation of a line is a variation on one that says the slope of a line is the same everywhere:
[tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}\ \Rightarrow\ (y_2-y_1)(x-x_1)=(x_2-x_1)(y-y_1)\\\\(y_2-y_1)(x-x_1)-(x_2-x_1)(y-y_1)=0[/tex]

Step-by-step explanation:
There were 436 tickets purchased for a major league baseball game. The general admission tickets cost $6.50 and the upper reserved tickets cost $8.00. The total amount of money spent was $3284.00. How many of each kind of ticket were purchased?
How many general admission tickets were purchased? ____
How many upper reserved tickets we purchased? ___
Answer:
How many general admission tickets were purchased? __136__
How many upper reserved tickets we purchased? _300_
Step-by-step explanation:
Let the number of general tickets = g.
Let the number of reserved tickets = r.
6.5g + 8r = 3284
g + r = 436
6.5g + 8r = 3284
(+) -8g + -8r = -3488
--------------------------------
-1.5g = -204
g = 136
g + r = 436
136 + r = 436
r = 300
Answer:
How many general admission tickets were purchased? __136__
How many upper reserved tickets we purchased? _300_
Answer:
136 general admission tickets were purchased
300 upper reserved tickets were purchased
Step-by-step explanation:
This is a classic system of equations problem. Let the number of general admission tickets sold be [tex]g[/tex] and the number of reserved tickets sold be [tex]r[/tex]. We can write the following system of equations:
[tex]\begin{cases}6.50g+8.00r=3284,\\g+r=436\end{cases}[/tex]
Multiply the second equation by -8 and add both equations to isolate [tex]g[/tex]:
[tex]-8(g+r)=-8(436),\\-8g-8r=-3488,\\\begin{cases}6.50g+8.00r=3284,\\-8g-8r=-3488\end{cases},\\-1.5g=-204,\\g=\frac{-204}{-1.5}=\boxed{136}[/tex]
Now substitute [tex]g=136[/tex] into [tex]g+r=436[/tex] to find the number of reserved tickets sold:
[tex]g+r=436,\\136+r=436,\\r=436-136=\boxed{300}[/tex]

Answer:
He can have 40 guinea pigs in the store.
Step-by-step explanation:
Since Jonas runs a pet store that sells guinea pigs, and he wants to ensure he has more than 1 pound of dry food for every five guinea pigs he has in the store, and he currently has 8 pounds of dry food, to know how many guinea pigs can he have in the store, the following equation must be performed:
1 = 5
8 = X
8 x 5 = X
40 = X
Therefore, he can have 40 guinea pigs in the store.

A fruit punch that contains 10% fruit juice is combined with 100% fruit juice. How many ounces of each should be used to make 51oz of a mixture that is 70% fruit juice?
9514 1404 393
Answer:
34 oz 100%17 oz 10%Step-by-step explanation:
Let j represent the number of ounces of 100% juice in the mix. Then (51-j) is the number of ounces of 10% juice. The total amount of fruit juice in the punch mix is ...
1.00j + 0.10(51 -j) = 0.70(51)
0.90j = 51(0.70 -0.10) . . . . . . . . collect j terms, subtract 0.10(51)
j = 51(0.60/0.90) = 51(2/3) = 34 . . . . . . . divide by the coefficient of j
The mixture should use 34 ounces of 100% juice and 17 ounces of 10% juice.
Why should you avoid investing all your money in familiar stocks?
A.
to increase the value of your returns
B.
to research unfamiliar industries that might reveal good investment opportunities
C.
to avoid selling at a loss
D.
to avoid diversifying into multiple investment options
Answer:
B.
Step-by-step explanation:
The main reason for this is to research unfamiliar industries that might reveal good investment opportunities. When you conform to what you know, you fall into a comfort zone. This prevents you from taking the time to investigate and learn new things. In this scenario, investing everything in familiar stocks will prevent you from looking for new investment options in different industries which could have led to incredible investment opportunities. Therefore, it is a better choice to invest a large portion in safer familiar stocks but leave a certain percentage for riskier and newer investments.

HELP PLEASE Which expressions are equivalent to 2(3/4x+7) -3(1/2x + -5)? Check all that apply.
Answer:
2., 3., 5.
Step-by-step explanation:
when we do the multiplications we see
2×3x/4 + 2×7 - 3×1x/2 + 3×5 = 3x/2 + 14 - 3x/2 + 15 = 29
as 3x/2 and -3x/2 reduce themselves in a sum to 0.
this gives answer option 2.
the other correct answer options are just splitting the addition part in a multiplication into their 2 "sub-multiplications" and adding these results.
the only correct ones (correctly maintaining our converting the signs) are 3 and 5.
option 4 suddenly converts the -3 factor into +3 without any other compensation. so, that is wrong.
and option 1 made again a sign mistake with -3×-5, which is correctly +15 and not -15.
A sled is moving down a steep hill in a straight line. At time ts, the
acceleration of the sled is ams-2 where a = 1/500(20t^2-t^3), 0 < t < 20. When t = 0
the sled is at rest at the top of the hill. Find the distance the sled travels in
the first 10 s of its motion.
Acceleration is the rate of change of velocity over time
The sled travels 100 meters in the first 10 seconds of its motion
How to determine the distanceThe acceleration function is given as:
[tex]a = \frac 1{500}(20t^2 - t^3)[/tex]
When t = 10, we have:
[tex]a = \frac 1{500}(20*10^2 - 10^3)[/tex]
[tex]a = 2[/tex]
The distance at 10 seconds is then calculated as;
[tex]S = ut +\frac 12 at^2[/tex]
Where:
u = initial velocity = 0
So, we have:
[tex]S = 0 *10 +\frac 12 * 2 * 10^2[/tex]
[tex]S =100[/tex]
Hence, the sled travels 100 meters in the first 10 seconds of its motion
