BabaBlast [244]

Answer:

a) 0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.

b) 0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons

Step-by-step explanation:

We use Venn's Equations for probabilities.

I am going to say that:

P(A) is the probability that a randomly selected person will feel guilty about wasting food.

P(B) is the probability that a randomly selected person will feel guilty about leaving lights on when not in a room.

0.12 probability that a randomly selected person will feel guilty for both of these reasons.

This means that $P(A \cap B) = 0.12$

0.27 probability that a randomly selected person will feel guilty about leaving lights on when not in a room.

This means that $P(B) = 0.27$

0.39 probability that a randomly selected person will feel guilty about wasting food

This means that $P(A) = 0.39$

a. What is the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both (to 2 decimals)?

$P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.39 + 0.27 - 0.12 = 0.54$

0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.

b. What is the probability that a randomly selected person will not feel guilty for either of these reasons (to 2 decimals)?

$p = 1 - P(A \cup B) = 1 - 0.54 = 0.46$

0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons

Ksju [112]

3t shirts cost $18

1 shirt will cost 18/3t = 6/t

7t shirts will then cost = (6/t)*7t = 42

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu

Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

$99.90 + 89.90 = 189.80$

Step 2: Find the sales tax of the result

$\frac{8}{100}\times 189.8 = 15.184$

Step 1: Convert 8% to fraction
$8\%= \frac{8}{100}$
Simplify
$\frac{8}{100} = \frac{2}{25}$
Step 2: Convert 189.80 to a fraction
$189.80 = \frac{189.8}{1}$
Step 3: Set it up
$\frac{2}{25}\times \frac{189.8}{1}$
Step 4: Cross divide
$189.80 \div 25 = 7.592\\2 \div 1 = 2$
Step 5: Multiply the result
$7.592 \times 2 = 15.184$

Step 3: Add the result from the total cost of both items

$189.80 + 15.184 = 204.98$

The total cost of the hats and boots including sales tax is 204.98 dollars

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.

Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is $x$ .

$180 = 44 + 90 + x$

$180 = 134 + x$

$x= 46$

The angle $y$ of the other triangle plus the angle $x$ of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

$90 = x + y$

$90 = 46 + y$

$y=44$

To find ?, we have

$180 = 58 + 44 +?$

$180 = 58 + 44 +?$

$? =78$

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

$180 = x + 50 + 25\\180 = x+ 75\\x=105$

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

$180 = 36 + 105 + y$

$180 = 141+ y$

$y=39$

$?=39$

BRAINLIEST ANSWER TO FIRST ANSWERER!!!!!

krok68 [10]

Answer:

Option C $\frac{1}{2}(185\°-x\°)=76\°$

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

so

$76\°=\frac{1}{2}(arc\ ST-arc\ XZ)$

we have

$arc\ ST=185\°$

$arc\ XZ=x\°$

substitute

$76\°=\frac{1}{2}(185\°-x\°)$

Rewrite

$\frac{1}{2}(185\°-x\°)=76\°$
