Answer:
rs 28500
Step-by-step explanation:
If she saves rs3420 and spends 88% we need to convert 88% to a decimal first.
88% = 88/100 = .88
Let m equal her monthly income.
m - .88m = 3420
.12m = 3420
.12m/.12 = 3420/.12
m = 3420/.12
m = 28500
He monthly income is rs28500.

Each of 12 refrigerators of a certain type has been returned to a distributor because of an audible, highpitched, oscillating noise when the refrigerators are running. Suppose that 7 of these refrigerators have a defective compressor and the other 5 have less serious problems. If the refrigerators are examined in random order, let X be the number among the first 6 examined that have a defective compressor. What is the probability that X exceeds its mean valueby more than 1 standard deviation?
Answer:
0.121
Step-by-step explanation:
From the given information:
Let X be a hypergeometric random variable. i.e X [tex]\sim[/tex] h (x;:6,7,12)
To determine the mean and the standard deviation of X of a hypergeometric random variable; we have:
[tex]\mu_x = E(X)[/tex]
[tex]\mu_x = 6 \times \dfrac{7}{12}[/tex]
[tex]\mu_x =1 \times \dfrac{7}{2}[/tex]
[tex]\mu_x =3.5[/tex]
The standard deviation is :
[tex]\sigma _x = \sqrt{(\dfrac{12-6}{12-1}) \times 6 \times (\dfrac{7}{12})\times (1-\dfrac{7}{12})}[/tex]
[tex]\sigma _x = \sqrt{(\dfrac{6}{11}) \times 6 \times (\dfrac{7}{12})\times (\dfrac{5}{12})}[/tex]
[tex]\sigma _x = \sqrt{\dfrac{35}{44}}[/tex]
[tex]\sigma _x = 0.892[/tex]
However, the inequality for the event showcasing how X exceeds its mean value by more than 1 standard deviation is :
[tex]X \geq \mu_x +\sigma_x[/tex]
[tex]X \geq 3.5 +0.892[/tex]
[tex]X \geq 4.392[/tex]
[tex]X \geq 5[/tex]
∴
[tex]P(X \geq \mu_x + \sigma_x ) = P(X \geq 5)[/tex]
[tex]P(X \geq \mu_x + \sigma_x ) = 0.121[/tex]
On a number line, what other number is the same distance from -2.8 as -7.2 is?
Answer;
1.6
Explanation
What we shall do here is to calculate the distance between the two points on the number line
Mathematically, that would be ;
-2.8 -(-7.2) = -2.8 + 7.2 = 4.4
This means that -7.2 is 4.4 units away from -2.8
So to find other number which is this same distance;
we have -2.8 + 4.4 = 1.6

Stephen rolls a fair dice 300 times.
How many times would Stephen expect to
roll a two?
Answer:
50 chances to roll a 2
Step-by-step explanation:
Since Stephen is most likely rolling a 6 sided dice, divide 300 by 6 because all sides have an equal change of being rolled.
300/6 = 50
How do you write, 24.23 as a mixed number in simplest form?

Step-by-step explanation:
I think this is the answer.

Answer:
24 23/100
Step-by-step explanation:
"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...
24 23/100
_____
Additional comment
You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.
Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.

What does the word “change “ tell you to do in “keep change flip” for dividing fractions? A) change the sing to multiplication b) change the sing to addition c) change the first fraction d) change the second fraction
Answer:
A
Step-by-step explanation:
Multiply by the reciprocal, also sometimes referred to as "Keep, Change, Flip." Here is how it works. You rewrite the division question as a multiplication question by flipping the second fraction over. Next, keep the first number, change the division to multiplication and then flip the second fraction over.
Answer:
d change the second fraction

Scientists from different fields are trying to understand how the global climate is reacting to the changes caused in nature, and by human activities. They have come up with conflicting interpretations. Which of these is the most likely outcome of differences in interpretations made by scientists on the issue of global climate? All old ideas would be discarded. Scientific evidence would be weakened. Scientists would look for new evidence. The limitations of science would be evident.
Answer:
Scientists would look for new evidence.
Step-by-step explanation:
Anytime scientists have different interpretations, they carry out more experments to look for new evidence. But this is after they must have tested their own hypothesis. If non of these are possible, they set out to get fresh evidences. Having different opinions would make them come up with new ideas with hope that their theories are valid. And it would also make them carry out more experiments for confirmation or for denial.

Pete bought a 16-ounce box of cereal for $3.58. What was the cost per ounce?
Answer:
Around 0.22 dollars or 22 cents
Step-by-step explanation:
We know that per 16 ounces it costs 3.58. We want the ounces to equal zero. To do that, we divide 16 by 0, but to keep it equal we need to divide 3.58 by 16. So...
16/16 = 1
3.58/16 = 0.22375
This means that every ounce of cereal, it costs 0.22375 dollars, but money can't go in the thousandths place, so we must round it to the hundredths place, which becomes 0.22 dollars, or 22 cents. I hope this helps and I hope it's not wrong but I don't think it is.

Okay so if your current scores are 93, 97, 89 and 81, You would have to score at least a 90. Even if you scored a 100%, the highest you would be able to make is a 92 average.
Step-by-step explanation:
Here's the thing about average, all you do is take all of the numbers, add them up, then divide them by the number of numbers there are.
For example, 93 + 97 + 89 + 81 = 360. There are 4 numbers so you would take 360 and divide it by 4 which gets you 90. 90 is your average.
To figure out the highest score you are able to get, take the highest score you can possibly score (100) and add it to the mix. 93 + 97 + 89 + 81 + 100 = 460. Now, there are 5 numbers. So you take 460 and divide it by 5 which will get you 92.

Suppose a friend tells you she paid a total of $19,875 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in : Lilburn with a percentage of 7%
Answer:
10.31%
Explanation:
This is the answer
friend bought the car in Lilburn with a percentage of 7% ie the price list of the car is $18483.75.
How do I calculate percentage?If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.The proportion therefore refers to a component per hundred.Per 100 is what the word percent means.The letter "%" stands for it.Percentage, which meaning "per 100," designates a portion of a total sum.The use of percentages is widespread and diverse.For instance, many statistics in the media, bank interest rates, retail discounts, and inflation rates are all expressed as percentages.For comprehending the financial aspects of daily life, percentages are crucial.The friend paid total of $19,875 for a car.
7% of 19,875 = 1391.25.
The list price of the car = 19,875 - 1391.25 = 18483.75
