Answer:
<h2><u><em>
Letter A</em></u></h2>
Step-by-step explanation:
First of all, we have to solve all the equations
First one is (4*1)-6
<em>We have to use PEMDAS</em>
<em>which stands for </em>
<em>Parenthesis</em>
<em>Exponents</em>
<em>Multiplication</em>
<em>Divison</em>
<em>Addition</em>
<em>Subtraction</em>
In (4*1)-6
You have to do 4*1 first ~ which equals 4
the next step would be 4-6 ~ which equals -2
The next equation would be (1*4)-6
First do 1*4 ~ which is 4
Next 4-6 ~ which again equals -2
Next equation is (1*6)-(4-6)
Parenthesis first, 1*6=6
4-6=-2
6-(-2)
which equals 8
Our next equation is 6-(1*4)
1*4=4
6-4~ which equals 2
Our last equation is 4*(1-6)
Parenthesis comes first, so it would be 1-6 first
which equals -5
4*(-5) would be our final step ~ which equals -20
All of our answers would be
-2 - from the top equation
-2 - from letter A
8 - from letter B
2 - from letter C
-20 - from letter D
which means <u><em>Letter A</em></u> is the answer.
Hope this is helpful.
180 degrees. It would be half of the circle.
Answer:
3:30PM
Step-by-step explanation:
Martina starting playing video games as soon as she got home from school. She played video games for 15 minutes. Then Martina helped clean the kitchen for 45 minutes. After the kitchen was clean, it took Martina 15 minutes to finish her homework. When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?
Step 1
We add up the minutes it took her to do things
= Minutes for video games + Minutes for cleaning the kitchen + Minutes for doing homework
= 15 minutes + 45 minutes + 15 minutes
= 75 minutes
= 1 hour 15 minutes
Step 2
When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?
This is calculated be subtracting 1 hour 15 minutes from 4:45 PM
= 4:45 PM - 1 : 15
= 3:30PM
Therefore, Martha got home from school by 3:30 PM
Answer:
1) The probability that the mean mpg for a random sample of 25 light vehicles is 0.042341.
2) between 20 and 25 --> 21-25/2.9 = -1.38
Step-by-step explanation:
Problem #1:
- Using the 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.
<h3><u>X < 20</u></h3>
- = z = 20 - 21/2.9/√25
- = z = -1/2.9/5
- = z = -1.72414
<h2><u><em>Now</em></u></h2>
<em>P-value from Z-Table:</em>
<h3><u>P(x<20) = 0.042341</u></h3>
Problem #2:
<h3>21-25/2.9 = -1.38</h3>
