Answer:

1,490,000

Step-by-step explanation:

Answer:

1490000?

Step-by-step explanation:

Answer:

64

Step-by-step explanation:

The part of money he spent =3/4

Let the total money Otto has be 'x'.

Then according to the question, we have

3/4x = 48

Multiply 4 on both the sides, we get

3x = 48 X 4

Divide 3 on both the sides, we get

x = 48 X 4 / 3

x = 64!

BOOM!

Answer:

Water =2/3× 100%=200/3%=66.67%

So land will be 100% - 66.67%

=33.33

Answer:

1. 30

2. -10

3. 48

Step-by-step explanation:

So for #1 I did:

3*2(6)+3*8(24) which equals 30

For #2 I did:

-5*4(-20)- -5*2(-10) which equals -10

For #3 I did:

8*10(80)-8*4(32) which equals 48

Answer:

188.27

Step-by-step explanation:

divide the starting number (1500) by 100 to get 1% then times by 3 to get the new number for tje start of tje next year.

After 1st- 1545

after 2nd year = 1591.35

After 3rd = 1639.1005

After 4th= 1688.273515

what he gained is 1688.273515-1500= 188.273515.

now round to 2 decimals = 188.27

Answer:

You paid $3.31 more

Step-by-step explanation:

Taking $5 and subtracting it with 1.69 you get 3.31

Answer:

The cost of 1 sparkling bottle in this week is less than last week, so we pay less this week. We pay $0.44 less this week. This week cost of 4 bottles is $5.

Answer:

A sample of 499 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this question, we have that:

[tex]\pi = 0.21[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 90% confidence level with an error of at most 0.03

We need a sample of n, which is found when [tex]M = 0.03[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.645\sqrt{\frac{0.21*0.79}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.645\sqrt{0.21*0.79}[/tex]

[tex]\sqrt{n} = \frac{1.645\sqrt{0.21*0.79}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.21*0.79}}{0.03})^2[/tex]

[tex]n = 498.81[/tex]

Rounding up

A sample of 499 is needed.

Answer:

5

Step-by-step explanation:

use pythagorean theorum and 75 is area. base is 2 and height is 2. base/2 ^2 = 1

1^2 + 2^2 = 5

Answer:

Slope is: y = 6x-4

Step-by-step explanation:

Divide both sides by 2 and you'll get the answer.

Answer:

6

Step-by-step explanation:

a slope equation. is y = mx + b

first you have to get y by itself by dividing both sides by 2

your new equation is

y= 6x + - 4 or just y = 6x - 4

the slope is the m value and in this case its 6

Answer:

okay so x=-3, y=4

Step-by-step explanation:

based off the top of my head -3+5*4=17 and -4*-3=12 12+3*4=24

Answer:

x=-3 ,y=4

Step-by-step explanation:

x+5y=17------(i)

-4x+3y=24------(ii)

use substitution method

x+5y=17

make x subject of the formula

x=17-5y-----(iii)

substitute equation (iii) into equation (ii)

-4x+3y=24

-4(17-5y)+3y=24

-68+20y+3y=24

23y=24+68

23y=92

divide both sides by 23

y=92/23

y=4

substitute y in equation (iii)

x=17-5y

x=17-5(4)

x=17-20

x=-3

I am joyous to assist you at any time.

**We base everything off of the x-coordinates because they are vertical-wise, which in this case is [tex]\displaystyle 2[/tex] and [tex]\displaystyle -1.[/tex]

Answer:

The options are not shown, so i will answer in a general way.

Let's define the variables:

h = number of hats

m = number of mugs.

We know that a total of 1000 items were ordered, then:

h + m = 1000

We also know that we have 3 times more mugs than hats, this can be written as:

m = 3*h

Now we have the system of equations:

h + m = 1000

m = 3*h

To solve these, we usually start by isolating one of the variables in one equation and then replace that in the other equation, but in this case, we already have m isolated in the second equation, then we can replace that in the first equation to get:

h + m = 1000

h + (3*h) = 1000

Now we can solve this equation for h, and find the number of hats ordered.

4*h = 1000

h = 1000/4 = 250

There were 250 hats ordered.

Answer:

b. Invalid, because the sample may not be representative of the population.

Step-by-step explanation:

A sample of around 10% of the population is needed to be representative.

In this question:

We have a population of 500,000, and a sample of 10,000.

10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.

Answer:

The probability is 0.58992 or simply 0.59

Step-by-step explanation:

We start by getting the z-scores of the diameter

we have this as follows;

Mathematically;

z-score = (x-mean)/SD

mean = 9.0 mm

SD = 1.5 mm

For 8.00 mm, we have

z = (8-9)/1.5 = -0.67

For 10.5 mm, we have

z = (10.5-9)/1.5 = 1

So the probability we want to calculate is;

P( 1 < x < -0.67)

we can calculate this using the standard normal distribution table

We have this as ;

P( x < -0.67) - P( x > 1) = 0.58992

Answer:

x = -23

y = -17

Step-by-step explanation:

[tex]x = - 6 + y \\ - 7x + 9y = 8 \\ \\ - 7( - 6 + y) + 9y = 8 \\ 42 - 7y + 9y = 8 \\ 2y = 8 - 42 \\ y = \frac{ - 34}{2} \\ y = - 17 \\ \\ x = - 6 + y \\ x = - 6 + ( - 17) \\ x = - 6 - 17 \\ x = - 23[/tex]

Answer:

Step-by-step explanation:

-7(-6 + y) + 9y = 8

42 - 7y + 9y = 8

2y + 42 = 8

2y = -34

y = -17

x = -6 - 17

x = -23

(-23, -17)

Answer:

Because your sleep deprived and your head is clumped up with more equations. :( i wish school was easy

Step-by-step explanation:

Answer:

It is complicated to answer but there are several factors which contribute toward the difficulty of learning how to solve problems. A person's motivation (anxiety) and poor understanding of the how and why of the material. But there are more internal factors as well, mental and metal learning handicaps. For example, Dyscalculia is a common condition where individuals have issues with making basic calculations and using those numbers the way their peers do. (Dyslexia, ADD/ADHAD, Dysgraphia, and Dyspraxia are other examples.

Answer:

-4 and -2

Step-by-step explanation:

The function has the factors (x + 4) and (x + 2). By setting these both to 0, you will find the zeros of the function.

x + 4 = 0

x = -4

x + 2 = 0

x = -2

Therefore, the zeros of the function are -4 and -2.
