Answer:

It means mathematics.

Lamoo thats wht it said in go-ogle

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

LK = 1/2RP

theorem: straight line joining the midpoints of two sides of a triangle is parallel to the third side and equal to half the length of the third side.

LK = 2x - 15 ; RP = 2x - 8

2x - 15 = 1/2(2x - 8)

2x - 15 = 2x - 8/2

2x - 15 = x - 4

Collect like terms and simplify

x = 11

Answer:

[tex] \frac{105}{6} [/tex]

Step-by-step explanation:

[tex] \frac{21}{2} + \frac{21}{3} [/tex]

lowest common multiple of 2 and 3 is 6

21×3 = 63

21×2= 42

they are now going to have the same denominator of 6

[tex] \frac{63}{6} + \frac{42}{6} [/tex]

now u are just gonna add the neumerators and keep the denominator

[tex] \frac{105}{6} [/tex]

Answer:

per year: $47,760 per year

per week: $918.46 per week

Step-by-step explanation:

$3980 per month x 12 months = $47,760 per year

$47,760 per year divided by 52 weeks = $918.4615384615

Since we're talking money, let's round off our answer to the hundredths place ($918.46 per week)

Double check our answer (918.46 x 52 = 47,760) great!

Answer:

47760 per year

918.46154 per week

Step-by-step explanation:

$3,980 x 12= $47760

$47760/52= $918.46154

The thing before the square root means that the answer can be positive and negative.

Answer:

0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

Step-by-step explanation:

For each cell, there are only two possible outcomes. Either it will least for at least 10,000 charge-discharge cycles, or it will not. Cells are independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

10 individual cells.

This means that [tex]n = 10[/tex]

95% probability

This means that [tex]p = 0.95[/tex]

What is the probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

This is P(X = 10).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 10) = C_{10,10}.(0.95)^{10}.(0.05)^{0} = 0.5987[/tex]

0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

Answer:

it'd be 95

Step-by-step explanation:

that's the nearest 10th

Answer: 97%

Step-by-step explanation:

15% + 38% + 44% = 97%

Answer:

The figure will change by a factor of 2.25.

Step-by-step explanation:

When the lengths (1-dimensional) change by a factor 1.5 (the definition of dilating a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.

Answer:

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Step-by-step explanation:

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

3% of books borrowed from a library in a year are downloaded.

This means that [tex]p = 0.03[/tex]

SRS of 75 books.

This means that [tex]n = 75[/tex]

What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books

By the Central Limit Theorem

Mean: [tex]\mu = p = 0.03[/tex]

Standard deviation: [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197[/tex]

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Answer:

x = 40

y = 15

Step-by-step explanation:

Given is an equilateral triangle.

Measure of each angle of an equilateral triangle is 60°.

Therefore,

(x + 20)° = 60°

x + 20 = 60

x = 60 - 20

x = 40

4y = 60

y = 60/4

y = 15

Answer:

h + 3

Step-by-step explanation:

Since Raj is 3 inches taller than Howard (h), Raj would be h + 3 inches taller than Raj, giving you your answer.

Answer:

h + 3

Step-by-step explanation:

h + 3

3 = they are 3 inches TALLER which means you need to add 3

h = Howards height

So all you would need to do is add Howards age by 3, and you will get Raj's height. They said that " Raj is 3 inches taller than Howard", so that means when you get Howard (h) you would need to add it by 3 (3 inches taller), and you will be able to get Raj's height.

Hope this helped!

Answer:

5

Step-by-step explanation:

Using the order operations, we go left to right, multiplying 3 by 2/3, giving us 2. Then we subtract 7 - 2 = 5.

Answer: 6miles

Step-by-step explanation: 6miles = 31680ft so 31680>31678

Answer:

Step-by-step explanation:

d₁ = 6 inches

r₁ = 3 inches

area = πr₁² = 9π in²

d₂ = 24 inches

r₂ = 12 inches

area = πr₂² = 144π in²

ratio of areas = (9π)/(144π) = 9/144 = 1/16

Answer:

61%

Step-by-step explanation:

7g+3b= 7th grade

4g+4b= 8th grade

70% chance of a girl getting picked from 7th grade

50% chance of a girl getting picked from 8th grade class

11g+7b= both classes

about 61% chance for both classes to be a girl picked?

Answer:

x=-8

(-8,-7)

Step-by-step explanation:

–9x + 9y = 9

–9x + 9(-7) = 9 (y=-7)

-9x-63=9

Both side +63

-9x=63+9

-9x=72

Both side divide   -9

x=-8

y=-7

(-8,-7)
