Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer

Answers

Answer 1

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light. If a car is driving down Dexter Street, what is the probability that it does not get stopped at either light?

Answers

Just multiply the sum of the light

The probability that it does not get stopped at either light is 14/25.

We have given

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light.

What is the formula for probability?

The probability of an event A is defined as the ratio of the number of favorable events that occurred in A /total number of events in a sample space

Red light for the first:

The Probability of the red light is 20 out of 100 so you would just find the difference which is 80%.

80/100

Red light for the second:

The Probability of the second red light is 30 out of 100 so you would just find the difference which is 70%.

70/100

The probability of not being stopped at either, multiply across and reduce.

[tex]80/100 * 70/100= 14/25[/tex]

Therefore, The probability that it does not get stopped at either light is 14/25.

How much did the two heaviest tomatoes weigh all together?

Answers

Answer:

1 and 6/8

Step-by-step explanation:

1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.

Solve 4/9 plus x =7/9 x =

Answers

Answer:

x = 1/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x + 4/9 = 7/9

Step 2: Subtract 4/9 from both sides.

x + 4/9 - 4/9 = 7/9 - 4/9

x = 1/3

Answer:

x = 1/3 (or) 3/9

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ (4/9) + x = 7/9

Then the value of x will be,

→ (4/9) + x = 7/9

→ x = (7/9) - (4/9)

→ x = (7 - 4)/9

→ x = 3/9

→ [ x = 1/3 ]

Hence, the value of x is 1/3.
