There is a 90% chance of rain tomorrow and a 30% chance that the baseball game will be postponed. What is the probability that it will rain tomorrow and the baseball game will be postponed?

3%
6%
27%
60%

Answers

Answer 1

Answer:

27%

explanation:

probability of both raining and base ball being postponed:

→ raining probability * base ball being postponed

→ 90% * 30%

→ 0.27

In percentage:

→ 27%

Answer 2

Answer:

.90 x .30 =.27

Step-by-step explanation:

Probability when you have A and B you can set to 100 A=will rain B=not rain

.90+.10 =1

The same is with the game being postponed.

.30+.70 =1

.90 x .30 =.27

when it says the probablitiy that it will rain tomorrow AND the baseball game will be postponed, you multiply the two probabilities

Sherwin has twice as many stamps as his friends Allan and Gene combined. Allen has 55 stamps in his collection. Sherwin has 200 stamps in his collection.How many stamps does Gene have in his collection?

The equation 2 (x + 55) = 200 models this situation. which choice shows the sequence of operations needed to solve this problem, using both arithmetic and alegbra?

Answers

Answer:

gene would have 45

Step-by-step explanation:

if you take 55 and times that by 2 you get 110 then gene would need a toyal of 90 to complete the 200 so if you divide 90 by 2 you get 45

Answer:

C is correct

Step-by-step explanation:

You divide by 2 and that leaves x+55=100-55=45

You would finish with 45

Geet sells television He earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Geet sells 11 televisions with extended​ warranties, he earns $990. How much is the fixed amount Geet earns for each​ television?

Answers

To figure this out, first multiply $30 by 11 to see how much money will come out of the full price:

$30×11=$330.

Next, subtract $330 from $990.

$990–$330=$660

The fixed price for 11 televisions is $660. So, divide $660 by 11.

$660÷11=$60.

So the fixed amount that Gerry earns for each television is $60.

Hope this helps! :D

Answers

Answer:

2a + 4 + 7b

Step-by-step explanation:

ohh so to do this umm if you want it to be easier you can put a different symbols under the ones with the same variable. like a dot under 4a and - 2a, a square under .....

but if you want to do it without that, all you have to do is add them like numbers

you can also move them closer to each other. for example:

4a - 2a + 8 - 4 + 7b

4 - 2 is 2 so you just have to write 2a

2a + 8 - 4 + 7b

simplify

2a + 4 + 7b

since there are no other numbers with the variable b the equation above is the answer

Answer: 63 m

explanation: finding the area of the entire rectangle (so if the triangle wasn’t there) would be 13 x 6 which equals 78. Now we find the area of the triangle, so 6 x 5 = 30/2=15. Then you do 78-15, which equals 63. Hope this helped!

89. first you find the area of the rectangle which is 8 x 13 = 104. Then you find the area of the triangle which is hb/2 the height is 6 and the base is 13-4-4= 5 so 30/2 is 15. Then you subtract the area of the triangle by the area of the rectangle. 104-15 so the answer is 89

Robots delivers goods in a factory. The sum of the maximum load of 3 robots (in kg) plus 120kg equals 220kg plus the max load of one robot.
What is the maximum load of a robot plus 1000kg?

Answers

Answer:

1050 kg

Step-by-step explanation:

Let the maximum load of each robot is x.

Then we have the following equation:

3x + 120 = x + 2203x - x = 220 - 1202x = 100x = 50

The maximum load of a robot is 50 kg:

50 + 1000 = 1050 kg

Hi! I hope you are enjoying your day!

Let's evaluate this expression for x.

Option D) (136-2a) + ( 3a + 39) = 180

Step-by-step explanation:

As per provided information .

XQR is a straight line So, sum of all angles formed on straight line is 180° .

This Means

∠XOM + ∠MOR = ∠XQR

On putting the given value we obtain

(136 - 2a) + (3a + 39) = 180

So, the required option is (D) (136 - 2a) + (3a + 39) = 180

You can solve it further to get the value of a .

Which of the following examples would show a negative trend?
A. height and weight of students
B. test scores and height of students
C. outside temperature and heating bill
D. none of these

Answers

Answer:  C. outside temperature and heating bill

Explanation:

A negative trend is when one variable goes up and the other variable goes down (or vice versa).

As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.

As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.

As the name implies, negative trend graphs have negative slopes for the regression lines.

C. Outside temperature and heating bill
