Answer:

$(-3,2 )$

Step-by-step explanation:

Midpoint Formula: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

Simply plug in your coordinates into the midpoint formula to find midpoint:

$(\frac{-1-5}{2},\frac{-5+9}{2} )$

$(\frac{-6}{2},\frac{4}{2} )$

$(-3,2 )$

Mary bought a paid of jeans and a sweater.The pair of jeans costs $30 and the sweater costs $35 .If sales tax is 6% ,how much di

ella [17]

$30 + $35 = $65

Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)

$65 + $3.90 = $68.90 ($65 + 6%)

OR

You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)

Make a tree diagram and find each probability.

Dafna11 [192]

Answer: a) probability that the game will be canceled= 45%

b) probability there will be a light drizzle and the game will not be canceled=20%

Step-by-step explanation:

Since we have given that

Probability of heavy fog is given by

$P(F)=0.70$

Probability of a light drizzle is given by

$P(D)=0.30$

Probability of getting canceled a softball game due to light drizzle is given by

$P(C\mid D)=0.80$

Probability of getting canceled a softball game due to heavy fog is given by

$P(C\mid F)=0.30$

a. Find the probability that the game will be canceled.

Probability of getting the game be cancelled is given by

$P(C)=P(F)\times P(C\mid F)+P(D)\times P(C\mid D)\\\\P(C)=0.70\times 0.30+0.30\times 0.80\\\\P(C)=0.45\\\\P(C)=45\%$

b. Find the probability there will be a light drizzle and the game will not be canceled.

Probability that there will be a light drizzle and the game will not be canceled is given by

$P(C'\mid D)=1-P(C\mid D)\\\\P(C'\mid D)=1-0.80\\\\P(C'\mid D)=0.20\\\\P(C'\mid D)=20\%$

Hence, a) probability that the game will be canceled= 45%

b) probability there will be a light drizzle and the game will not be canceled=20%

Need help on precalcues

Vinvika [58]

5 ≥ 2, so the second rule of <em>C(x)</em> applies :

<em>C</em> (5) = 25 + 3•(5 - 2) = 25 + 3•3 = 25 + 9 = 34

Elizabeth earns $9 an hour at her job now. She can represent the total she makes in a month using the expression 9t. Elizabeth h

irga5000 [103]

So, if she now makes 9 dollars per hour and she wants to make 2 dollars more per hour, this means she will make 9+2=11

11 dollars per hour,

So the correct answer is 11t - option C.

we can also write it as

(9+2)t

this is equivalent to 11t.
