Answer:
total number of parts of a 2:5 ratio are 7 as 2+5 = 7
let us assume are number to be 49
the first part will be 49/7 × 2 = 14
the second part will be 49/7 × 5 = 35
It is unknown since there is a 50-50 chance it could be heads or tails
Answer: (4,8) which is choice A
f = 2/3 is the scale factor
x = 6 and y = 12 pair up to get the coordinates for point K's location
multiply f by x and y to get the new location
f*x = (2/3)*6 = (2/3)*(6/1) = (2*6)/(3*1) = 12/3 = 4
f*y = (2/3)*12 = (2/3)*(12/1) = (2*12)/(3*1) = 24/3 = 8
The results we get are 4 and 8. So (6,12) moves to (4,8)
This scale factor 2/3 = 0.667 is less than 1, so the image is smaller compared to the pre-image.
Answer:
The mean for the sample mean distribution is 297 minutes.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
Using the Central Limit Theorem for Means, what is the mean for the sample mean distribution?
The mean is the same as the population mean, that is, 297 minutes.
Answer:
all real numbers
Step-by-step explanation:
3x-8 = -x + 4(x-2)
distributive property:
3x - 8 = -x + 4x-8
Combine like terms:
(add 3x to both sides)
-8 = -8
That means that x can be any number, because in the end, x will be canceled out from the equation.
