Male mosquitos have pretty short lifespans. Males of a certain species have lifespans that are strongly skewed to the right with a mean of 888 days and a standard deviation of 666 days. A biologist collects a random sample of 505050 of these male mosquitos and observes them to calculate the sample mean lifespan. We can assume that the mosquitos in each sample are independent.
What will be the shape of the sampling distribution of the sample mean lifespan?
Answer:
Approximately Normal
Step-by-step explanation:
The sample size is large (n50≥30n), so the sampling distribution of the sample mean will be approximately normal even though the population is skewed.
Suzie is going to run for 32 minutes. She can run 1 mile in 5 minutes and she cools off for 7
minutes. How many miles can she run in her time limit?
Answer:
She can run 3 miles in her time limit.
Step-by-step explanation:
Suzie is going to run for 32 minutes. She run 1 mile in 5 minutes and she cools off for 7 minutes
5+7=12 minutes
she runs 1 mile needs 12 minutes total
32÷12=2⋯8
8-5=3 minutes
2+1=3 3×1=3 miles
She can run 3 miles in her time limit.

Find the x - and y -intercepts of the graph of the linear equation -4x+8y=-16 .
The x -intercept is
.
The y -intercept is
.
Answer:
x -intercept is 4
y -intercept is -2
Step-by-step explanation:
SOLUTION:
(x -intercept)
-4x+8y= -16
-4x+8×0= -16
-4x+0= -16
-4x/-4 = -16/-4 (divide both sides by -4)
x=4
______________________
(y -intercept)
-4x+8y= -16
-4×0+8y= -16
0+8y= -16
8y/8 = -16/8 (divide both sides by 8)
y= -2

Answer:
t = [tex]\sqrt{63} \\[/tex] or 7.94
Step-by-step explanation:
Yes, you have to use the Pythagorean theorem
A^2+B^2=C^2
So, A=9, B=t, C=12
9^2+t^2=12^2
81+t^2=144

PLZZZZZZZZZZZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Step-by-step explanation:
Your first step is to figure out which variable you want to cancel out.
Luckily, all these problems have x or y already set up to eliminate.
You can find these variables because they are opposite signs of each other, such as -x and x
Add the y's together and the #'s on the other side together, then solve to find the 2nd variable. Once you find one, you can plug that answer into the easier of the two equations and solve for the other variable.

T 4
Q
X= 58/3
PS = 107/3
Answer:
x = 56/3
PS = 103/3
Step-by-step explanation:
Perimeter: (4x + 1) + 2(2x - 3) + (4 + 4 + 4x + 1) = 228
Collect and combine like terms: 12x + 4 = 228
Subtract 4 from both sides: 12x = 224
Divide both sides by 12: x = 56/3
PS = (2 x 56/3) - 3 = 103/3
I need to determine the figure is a parallelogram using the slope formula
Answer:
KL // MN & KN // LM
Step-by-step explanation:
One property of parallelogram is every two opposite sides are parallel to each other and if a two lines (sides) are parallel so they must have the same slope.
In the parallelogram KLMN:
using the slope formula = y2-y1/x2-x1
plug the numbers: KL // MN & KN // LM so KLMN is a parallelogram

How do I find the product of (10−11i) and its conjugate?
Step-by-step explanation:
Given - 10 - 11i
1st requirement - conjugate
Z = X + Yi
Change the sign between x & yi to find the conjugate of a complex
number.
Z = 10 + 11i
Now multiply the conjugate & the 1st complex number
=10-11i × 10+11i
= (10 × 10)+ (10× 11i)+ (-11i × 10) + (-11i × 11i)
Recall that i = √-1
= 100 + 110i - 110i + (-(-(11 × 11))...since √-1 × √-1 = -1.
= 100 + 121
= 221.

What are Measurements?Measurement is the method of comparing the properties of a quantity or object using a standard quantity.
Measurement is essential to determine the quantity of any object
1 dollar = 4 quarters
1 dollar = 10 dimes
1 dollar = 20 nickels
1 dollar = 100 pennies
We have to calculate the total dollar measurement of 2 quarters, 3 dimes, 3 nickels, and 5 pennies.
4 quarters = 1 dollar
2 quarters = 2/4 dollars
= 0.5 dollars
10 dimes = 1 dollar
3 dimes = 3/10 dollar
= 0.3 dollar
20 nickels = 1 dollar
3 nickels = 3/20 dollar
= 0.15 dollar
100 pennies = 1 dollar
5 pennies = 5/100 dollar
= 0.05 dollar
Total currency value = 0.5 dollars + 0.3 dollar + 0.15 dollar + 0.05 dollar
= 1 dollar
Hence the total worth of coins given is 1 dollar.

(SAT Prep) Find the value of x
Answer:
x=70°
Step-by-step explanation:
y=350° (angle inside triangle equal to 35°)
x=180-y-(180-105)
x=70°
Hope it helps!
Solution:
We can see that two lines are parallel, intersecting a line. We can also see a triangle formed with the lines.
=> x + (180 - 105) + 35 = 180 [The '35' came from Alternate inner angles]=> x + 75 + 35 = 180=> x + 110 = 180=> x = 180 - 110=> x = 70The measure of x is 70°.
A half-ton pickup truck has a curb weight (weight empty but ready-to-drive) of 5/2 ton. If curb weight is evenly divided among four truck tires, how much weight is each tire bearing?
NO LINKS!!!
Answer:
0.625 tons or 5/8 tons
Step-by-step explanation:
(5/2)/4
0.625 tons or 5/8
Answer:
5/8 ton
Step-by-step explanation:
1/4 of 5/2 ton is on each tire, so the weight it is bearing is ...
(1/4)(5/2 ton) = 5/8 ton
Each tire is bearing 5/8 ton.
_____
Additional comment
If that is a US short ton (2000 lb), then the weight on each tire is 1250 pounds. If the tires are inflated to 50 pounds per square inch, then the area of rubber on the road at each tire is 1250 lb/(50 lb/in^2) = 25 in^2. That's the size of a 5-inch square.
