Answer:

The product of 8 and 7 is greater than 50

Answer:

8x > 50

Step-by-step explanation:

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:

4) x > 20

5-10) I cant see the numbers on the graph

Step-by-step explanation:

Answer:

For the graphs you have to basically make those words into a mathematical equation to make more sense like for the first problem in which..

x>30

remember, open circles mean that its it can't be greater for symbols like < and >

closed circles are for inequalities that are greater than or equal to or less than or equal to which are these symbols: ≤ and ≥

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:

Puts the dots where the A,B,C,D dots are and move them 5 units to the right.

Example:

Original place

A=(2,5)

Moved 4 units to the right:

A'=(6,5)

Here are some tips:

Up= Y value goes up

Down= Y value goes down

Right= X value goes up

Left X value goes down

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:

The average number of skiers in Lavilla are 1,600 skiers

Step-by-step explanation:

The number of skiers that come to Lavilla on average each week = 2,800 skiers

The number of days each skier stays in Lavilla = 4 days

The amount each skier spends in local restaurants daily = $40

According to Little's Law, we have;

L = λ·W

Where;

L = The average number of skiers in Lavilla

λ = The effective arrival rate of the skiers = 2,800 skiers per week arrive

W = The number of days each skier stays at Lavilla = 4 days = 4/7 week

The average number of skiers in Lavilla, 'L', is therefore, given as follows;

L = 2,800 skiers/weel × (4/7) week = 1,600 skiers

The average number of skiers in Lavilla, L = 1,600 skiers

Answer:

It means mathematics.

Lamoo thats wht it said in go-ogle

Step-by-step explanation:

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:

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.

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

Answer:

99.7% of the students have grade point averages that are between 1.42 and 3.7

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 2.56 and standard deviation of 0.38.

Using the empirical rule, what percentage of the students have grade point averages that are between 1.42 and 3.7?

1.42 = 2.56 - 3*0.38

3.7 = 2.56 + 3*0.38

So both these scores are within 3 standard deviations of the mean, which means that 99.7% of the students have grade point averages that are between 1.42 and 3.7

j. at most three of them occur.

EFG U (EFG)'

Step-by-step explanation:

Events = {E, F, G}

a.) only E occurs :

E((FUG)') ; E and not F or G

b.) both E and G but not F

EG(F') ; both E and G and not F

C.) Atleast one of the events :

(E U G U F) ; Either E or F or G

d.) Atleast two of the events

(EG U EF U GF) ; Either EG or EF or GF occurs

E.) all three occurs

(EGF) ; All three events, E, G and F occurs

F.) none of the events occur :

(E U G U F)' ; Neither E, G nor F occurs

G.) At most one of the events occur

(EG U EF U GF)' ; complement of atleast two) at most one

H.) at most two of them occur

(E' U G' U F') ; Either E , F or G does not occur

I.) exactly two of them occur;

(EG U EF U GF) * (EGF)' ; Exactly two events occurs and all three events Do not occur

j. at most three of them occur.

EFG U (EFG)' ; All three events occur union all three events do not occur

Answer:

angles 3 5 and 7 equal 113

angles 2 4 6 and 8 equal 67

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

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]
