Which mathematical property is demonstrated? 72+(28+93)=(72+28)+93 a. communicative property of addition

b. associative property of addition

The given number = 72 + (28 + 93) = (72 + 28) + 93

This given number is an example of associative property of addition.

because associative property of addition is a process where you are going to add the given numbers in a different group but still able to get the same answer.

=> 72 + (28 + 93) = (72 + 28) + 93

=> 72 + 121 = 100 + 93

=> 193 = 193

This given number is an example of associative property of addition.

because associative property of addition is a process where you are going to add the given numbers in a different group but still able to get the same answer.

=> 72 + (28 + 93) = (72 + 28) + 93

=> 72 + 121 = 100 + 93

=> 193 = 193

Mirek invests £6000 at a compound interest rate of 1.5% per year. He wants to earn more than £1000 interest.

Work out the least time, in whole years, that this will take.

Answer:

11 years

Step-by-step explanation:

100%+1.5= 1.015

6000 *1.01n >7000

6000 X 1.015 to power of 10 equals = 6963

6000 X 1.015 to power of 11 = 7067

Explain how unwrapping a present is used as an analogy for solving an equation. How do you "unwrap" with an equation? ...?

Here is an analogy comparing between unwrapping a present and unwrapping an equation. Both actions do require following a process. You cannot just skip one step in order to arrive at the answer. Just like unwrapping a present, you need to do it in order. First, you take off the ribbon, then you start to unwrap the wrapper until you see the actual gift. On the other hand, when you are unwrapping an equation, you also follow a certain step. You are given a certain formula and values. What you need to do next is to substitute, do the solution, until it is simplified. And lastly, there you have it. You can now see the actual answer. Hope this answer helps.

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run?

(1 hour) x (60 min/hr) x (60 sec/min) = 3,600 seconds

(3 yards/sec) x (3,600 sec/hour) x (1 mile / 1,760 yards) =

( 3 x 3,600 / 1,760 ) mile/hour = 6.14 miles/hour (rounded)

use inductive reasoning to describe the pattern then find the next two numbers in the pattern 16,18,20,22

I see that 16 increases by 2 to get 18.

I see that 18 increases by 2 to get 20.

I see that 20 does the same to get 22.

SO - using inductive reasoning, I deduce that the number after 22 will be 24.

I deduce that the number after 24 will be 26.

They all increase by 2

A scientist is studying tulips and daffodils. The scientist estimates that there are 150 tulips in the population of 600 tulips and daffodils. He chooses flowers from random parts of the garden to study. Which best explains how he can choose a random sample of flowers to represent the population? He can choose 50 flowers. He can choose 25 tulips and 25 daffodils. He can choose 15 tulips and 60 daffodils. He can choose 10 tulips and 30 daffodils.

Answer: Last Option is correct.

Step-by-step explanation:

Since we have given that

Total number of tulips and daffodils = 600

Number of tulips = 150

Number of daffodils is given by

So, We can get the ratio of tulips to daffodils which is given by

So, we need to choose a random sample of flowers to represent the population.

1) He can choose 50 flowers.

As there are 1:3 of tulip and daffodils flowers but if we divide 50 by 4 it will give a decimal number, so it can't represent the required thing.

2) He can choose 25 tulips and 25 daffodils

As they are divided into 1:1 so, it can't represent the 1:3 tulip to daffodils population.

3) He can choose 15 tulips and 60 daffodils

As it is divided into 1:4 inspite of 1:3.So it can't represent the required population.

4) He can choose 10 tulips and 30 daffodils.

So, Last option which states that he can choose 10 tulips and 30 daffodils as in this case the ratio of tulips to daffodils is 1:3.

Hence, Last Option is correct.

Answer: D. He can choose 10 tulips and 30 daffodils.

A confidence interval measures how likely a certain conclusion is true. True or False

Yes, A confidence interval measures likely a certain conclusion.

What are interval measures?The numerical scale used to measure interval data has equal gaps between neighboring values. "Intervals" are the names for these distances. An interval scale differs from a ratio scale in that there is no genuine zero on it.

An estimate of the parameters within which a population mean might be located is known as a confidence interval. Confidence intervals are generated for a population with a known standard deviation using the sample mean as a point estimate, the z-score as a reliability factor, and the standard error.

Therefore, A confidence interval measures probable a conclusion is to be true.

#SPJ2

Answer:

True

Step-by-step explanation:

A confidence interval is an estimate of the limits within which a population mean would be found. For a given population with a known standard deviation, confidence intervals are calculated using the mean of a sample as a point estimate, a z-score as a reliability factor, and the standard error.

a student answered 86 problems on a test correctly and received a grade of 98% how many problems were on the test?

I am not sure but my best guess is that there was 88 questions on the test. If you multiply .98 by 88 (.98*88) it should equal 86.24, which rounded is 86. I am not sure but that is my best guess, I do not know where that 88 came from though, it just popped in my mind. Hope it helps! :)

86/x = 98%

86/x = .98

86 = .98x

86/.98 = x

87.76 = x

round up to 88
