(6) Give the equation of the line passing through the points (1,5) and (-2, 6) in
Bas_tet [7]

Answer:

⅓x + y = 5⅓

or

⅓x + y = 5.3333333

or

⅓x + y = 16/3

Step-by-step explanation:

Solve for slope using rise/run

Y2 - Y1 / X2 - X1

(6) - (5) / (-2) - (1)

1 / -3

Slope: -⅓

y = -⅓x + b

solve for b using one of the points

I'll be using (1,5)

Substitute the point into the equation

5 = -⅓(1) + b

5 = -⅓ + b (add ⅓ to both sides)

+⅓ +⅓

5⅓ = b

5⅓ can also be written as 16/3 or 5.333333

The equation is now:

y = -⅓x + 5⅓

Convert to standard form by adding ⅓x to both sides

y = -⅓x + 5⅓

+⅓x +⅓x

Solution: ⅓x + y = 5⅓

A "thrift" is another name for a commercial bank. True or False
elixir [45]

A thrift is a kind of bank that arranges mortgages (mostly for home ownership) and sets up accounts to receive deposits.

The statement is actually false. The difference is in who they can borrow from and whether or not they are set up for profit. Thrifts are usually non profit.

Of interest is to test the hypothesis that the mean length of all face-to-face meetings and the mean length of all Zoom meetings
Goshia [24]

Answer:

Null hypothesis: \mu_1 = \mu_2 = ..... \mu_j , j =1,2,....,n

Alternative hypothesis: \mu_i \neq \mu_j , i,j =1,2,....,n

The alternative hypothesis for this case is that at least one mean is different from the others.

And the best method for this case is an ANOVA test.

Step-by-step explanation:

For this case we wnat to test if all the mean length of all face-to-face meetings and the mean length of all Zoom meetings are the same. So then the system of hypothesis are:

Null hypothesis: \mu_1 = \mu_2 = ..... \mu_j , j =1,2,....,n

Alternative hypothesis: \mu_i \neq \mu_j , i,j =1,2,....,n

The alternative hypothesis for this case is that at least one mean is different from the others.

And the best method for this case is an ANOVA test.

Mekhanik [1.2K]

Answer:

A. $130.50

B. 150%

C. 50%

Step-by-step explanation:

First, find 50% of 87 and add it to find the new price.

87 x 0.5 = 43.5

87 + 43.5 = 130.5

Then, find the percent by doing 130.5 ÷ 87, which is 150%

Calculate the percent increase by doing (130.5-87) ÷ 87, which is 50%
