Step-by-step explanation:
The average fuel efficiency of U.S. light vehicles (cars, SUVs, minivans, vans, and light trucks) for 2005 was 21 mpg. If the standard deviation of the population was 2.9 and the gas ratings were normally distributed, what is the probability that the mean mpg for a random sample of 25 light vehicles is Under 20
Answer:
0.042341
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ/n, where
x is the raw score = 20 mpg
μ is the population mean = 21 mpg
σ is the population standard deviation = 2.9
n = random number of samples
Hence:
For x < 20
= z = 20 - 21/2.9/√25
= z = -1/2.9/5
= z = -1.72414
P-value from Z-Table:
P(x<20) = 0.042341
The probability that the mean mpg for a random sample of 25 light vehicles is Under 20 mpg is 0.042341
The probability that the mean mpg for a random sample of 25 light vehicles is 0.042341
Calculation:Here we used z score formula
z = (x-μ)/σ/n, wherex is the raw score = 20 mpgμ is the population mean = 21 mpgσ is the population standard deviation = 2.9n = random number of samplesSo,
For x < 20
= z = 20 - 21/2.9/√25
= z = -1/2.9/5
= z = -1.72414
Now
P-value from Z-Table:
P(x<20) = 0.042341

URGENT!!!! Han earns $48 for babysitting 3 hours. How much money does Han make per hour? Explain
your reasoning. :)
Answer:
Step-by-step explanation:
If he earns $48 dollars in 3 hours, you need to divide 48 by 3 to work out how much he makes per hour. and 48/3 = 16. So he makes $16 dollars an hour.
Answer:
16$
Step-by-step explanation:
You would have to divide the number of hours he worked for three days by the days he worked in order to find out what he would earn per hour.
This means the answer is 16 dollars per hour.

please help!! i’ll give brainly
Answer:
1: y = 3x + 1 Swap sides so that all variable terms are on the left hand side. 3x + 1 = y Subtract 1 from both sides.
2: y(x) = 5x, y(x) is just another way of writing the equation to indicate that y is a function of x. You could simply write it as y = 5x. Thus if we compare to the standard form equation y = ax + b, a=5 and b=0. Thus the y-intercept is zero.
3: the answer is simply 0
4: y-(1/5*x-10)=0

Question 18 options:
A)
x = –5, x = 4∕5
B)
x = –4∕5, x = 5
C)
x = 4∕5, x = 5
Step-by-step explanation:
Hey there!
Given;
[tex] = (x - 4)( {x}^{2} + 2x - 5)[/tex]
[tex] = x( {x}^{2} + 2x - 5) - 4( {x}^{2} + 2x - 5)[/tex]
[tex] = {x}^{3} + 2 {x}^{2} - 5x - 4 {x}^{2} - 8x + 20[/tex]
[tex] = {x}^{3} - 2 {x}^{2} - 13x + 20[/tex]
Therefore, Option D is correct answer.
Q.no.
Given;
[tex] =( 4 {x}^{3} + 9xy + 8y) - (3 {x}^{3} + 5xy - 8y)[/tex]
[tex] = 4 {x}^{3} + 9xy + 8y - 3 {x}^{3} - 5xy + 8y[/tex]
[tex] = {x}^{3} + 4xy + 16y[/tex]
Therefore, answer is Option D.
Qno.
Given;
[tex]5 {x}^{2} + 29x + 20 = 0[/tex]
[tex]5 {x}^{2} + (25 + 4)x + 20 = 0[/tex]
[tex]5 {x}^{2} + 25x + 4x + 20 = 0[/tex]
[tex]5x(x + 5) + 4(x + 5) = 0[/tex]
(5x + 4)(x + 5) =0
Either (5x+4)= 0,
5x = -4
X = -4/5
Or, X+5 = 0
X = -5.
Therefore, X= -5, -4/5.

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?
Answer : The number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
Step-by-step explanation :
As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.
Now we have to determine the number of bottles should the pharmacy technician prepare to provide the required dose.
As,
The pharmacy has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]
The pharmacy has stock albumin = 12.5 mL
So,
Number of bottles should the pharmacy technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]
Number of bottles should the pharmacy technician prepare to provide the required dose = 4
Therefore, the number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
In a three hour TV broadcast the commercials show 29% of the time. How many minutes of commercials are shown each hour? Round to the nearest tenth of a minute
Answer:
There are 17.4 minutes of commercials are shown each hour.
Step-by-step explanation:
An hour has 60 minutes.
So in 3 hours, there are 3*60 = 180 minutes.
The commercials show 29% of the time.
So we have 0.29*180 = 52.2 minutes, in total, of commercial.
Per hour, we have 52.2/3 = 17.4 minutes of commercial.
