Answer:
250 mph
Step-by-step explanation:
Speed of car = Distance / Time =
The speed of the plane was 200 mph faster than the speed of the car.
Speed of car = X mph
Speed of plane = 200 + X mph
Evans drove 250 miles in the same amount of time...
Speed = Distance / Time
Time = Distance / Speed
T = 250 / X ........(i)
same amount of time that it took a turbo propeller plane to travel 1250 miles.
Time = Distance / Speed
T = 1250 / (200 + X) .......(ii)
Substitute the value of T in eqn (i) to eqn (ii)
250 / X = 1250 / (250 + X)
250 (200 + X) = 1250 X
50000 + 250 X = 1250 X
1250 X - 250 X = 50000
1000X = 50000
X = 50000 / 1000 = 50
Speed of plane = 200 + X mph = 200 + 50 = 250 mph
An unfair coin with a probability of tails as 0.55 is tossed 8 times. Find the probability that a tail shows up more than 2 times.
Answer:
0.9115
Step-by-step explanation:
Using a binomial probability function :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
Probability of success, p = 0.55
1 - p = 1 - 0.55 = 0.45
n = 8
x = 2
P(x > 2 ) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x =8)
To save computation time, we could use the binomial probability calculator :
P(x > 2 ) = 0.9115
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
An automobile company manufactures hatchbacks, sedans, and sports cars. The company conducted a magazine survey to determine the demand for its cars in each of these categories. The results of the survey showed that 78% of those polled preferred hatchbacks, 19% voted for sedans, and 3% voted for sports cars.
If the company expects to sell 15,000 cars in a month, it should plan on
of the cars being sedans.

What is another way to represent "-4 degrees Celsius"?
Answer:
Step-by-step explanation:
You could also use increments of 4 degrees instead, so the first line to the right of the zero point represents 4 degrees Celsius, the second represents 8 degrees and so on. Having each line represent 4 degrees is useful, since the temperatures where Celsius and Fahrenheit correspond are multiples of 4 in both scales. It's ok if you give brainliest to the other person who answered first
what is b? Explanation and answer please.
Answer:
b=6
Step-by-step explanation:
line b + 14.5 is parallel to line 20.5
so 20.5= b + 14.5
b=6 when you subtract the 14.5

Answer:
4th option
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift left by a units
• If a < 0 then shift right by a units
-------------------------------------------------
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Then
g(x) = [tex](\frac{1}{4}) ^{x-3}[/tex] + 5
is f(x) shifted 3 units right and 5 units up
Which statement about f(x) = x^2 + 16x + 3 is true
A. The function has a maximum value of 3
B. The function has a maximum value of 16
C. The function has a minimum value of -8
D. The function has a minimum value of -61
Answer:
D
Step-by-step explanation:
Given a quadratic function in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then minimum value
• If a < 0 then minimum value
For
f(x) = x² + 16x + 3
a = 1 > 0 then f(x) has a minimum value
The minimum is the value of the y- coordinate of the vertex.
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
Here a = 1 and b = 16 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8
To find the y- coordinate of the vertex, substitute x = - 8 into f(x)
f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61
Thus the function has a minimum value of - 61 → D

La quinta parte de la suma de un cierto numero y 8 es igual a dicho numero disminuido en 3 .Represente simbolicamente
Answer:
50
Step-by-step explanation:
The computation is shown below:
According to the question
(X ÷ 5) - 8 = 3
Now
X = (3 + 8) × 5
X = 55
Now in the case when it is decreased by 5
So, the value would be
= 55 - 5
= 50
