Answer:
x=5
m<R= 75°
m<O= 75°
m<F= 30°
a triangle is 180°
75°+75°=150°
180°-150°= 30°
because it is an isosceles triangle, angles O and R are equivalent. Subtract the sum of angles O and R from 180 to find the measurement of angle F

Answer:
55 +20 = 75
then she cuts 15
75-15 = 60
60 cm in milimiters
50*10
600 milimeters is the answer
Step-by-step explanation:
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>
The correct answer is: $20
Explanation:
3 pounds of hamburger is $6.
1 pound of hamburger is 
Now,
10 pounds of hamburger is 
Hence the correct answer is $20.
Total area = 4 × 8.5 × 11 = 374 in²
374 in² = 374/144 = 2.597 ft²
