Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)

----------------------------------------------------

Explanation:

To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head

In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)

Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D

Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S

Answer:

31x³-60x²+7x-75

Step-by-step explanation:

(30x³-49x³+7x)+(50x³-60x²-75)

(-19x³+7x)+(50x³-60x²-75)

-19x³+50x³+7x-60x²-75

31x³-60x²+7x-75

Gennadij [26K]

Answer:

D. Both B and C

Step-by-step explanation:

The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:

5 x 10^9 /50= 0.1 * 10^9 = 1*10^8

The answer will be D since 1 x 10^8 and 100,000,000 is the same number

In a T-test, if your n=459, your DF is:<br><br> A. 459<br> B. 460<br> C. 458<br> D. A&amp;C
Stels [109]

Answer:

DF = 458

Step-by-step explanation:

In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.

The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;

DF = n - 1

where n is the sample size

Given n is 459, DF = 459 - 1 = 458

Therefore, DF = 458

A cable television company had 8500 subscribers in a suburban community. The company offers two premium channels, A and
ASHA 777 [7]
This is a problem on  a venn diagram in which the problem determines the number of subscribers that are mutually heeding for channel A and channel B. The equation to be followed is 

U = U' + A + B + AandB
Substituting,
8500 = 5140 + 2450+1980- AandB
AandB = 1070 subscribers
