Seven pounds of grapes cost $10.43. How much would 4 pounds cost?​

Answer:

y=3x-1

Step-by-step explanation:

First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.

(2,5) (10,29)

The equation for slope is m=y2-y1/x2-x1

m=29-5/10-2

m=24/8

m=3

Now, we will find the variable B.

5=3(2)+b

5=6+b

-1=b

That's how we get the equation!

y=3x-1

Answer:y= 3x-1

Step-by-step explanation:

m= y2-y1/ x2-x1=

29-5/10-2=3

Now,use: y-y1= m(x-x1)

y-5=3( x-2)

y= 3x-1

Answer:

(c). [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The cosine is the "x" coordinate of the terminal point on the unit circle.

Thus the answer is (c). [tex]\frac{1}{2}[/tex]

Answer:

you just add X=8 to 5x-6

You always have to multiply it

so its 5•8-6= 34

Answer: The answer is 34

Step-by-step explanation: all you had to do was think all of the answers below are high numbers so you most likely had to multiply so i did 5x8-6=34

Answer:

B and D

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

she got 35 is positive 35

she bought something for 15 and something for 7 is negative 15 and 7

she got 10 is positive 10

+35  +  (-15)  +  (-7)  +  10

35-15-7+10

Answer:

x= -2

Step-by-step explanation:

To graph it. You know that the slope(m) is 2 and y-int is 4.

So put a point on (0, 4), (1, 6) and (0, 2) then use your ruler and just draw a straight line hitting all these points.

Ex.

When x=1

y=2x+4

y=2(1)+4

y=6

(1, 6) is a point

To solve for x-int, make y=0 because it's on the x-axis

y=2x+4

0=2x+4

-4=2x

x=-2

Answer:  x intercept= (-2,0)

y intercept= (0,4)

Answer:

The answer is 6x-4 if you need to combine the like terms.

Step-by-step explanation:

So first you see if there are any like terms so I see 10x and -4x so I add them together and get 6x. I look for other like terms and find 3 and -7 and add those together so I get -4. Then you combine the 2 answers and get 6x-4. I hope this helps you! If you need any other help please let me know in the comments.

Answer:

6x-4

Answer:

Blake's car gets better mileage

Step-by-step explanation:

In order to find how many miles you get per gallon, you would do miles/gallons

As I'm typing this I realize it makes no sense but pretty much you just do 300/20 which is 15 mpg, and 495/15 which is 33 mpg, therefore Blake's car is better

Correct choice: b. $1221.00

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested on each compounding period. When it happens interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

The initial deposit on a savings account is P = $1000. The account provides an annual rate of r = 4% = 0.04 compounded monthly. The value of n is 12 since there are 12 months in a year. The money is left in the account for t=5 years. Substituting the values:

[tex]{\displaystyle A=\$1000\left(1+{\frac {0.04}{12}}\right)^{12*5}}[/tex]

[tex]{\displaystyle A=\$1000\left(1.00333}\right)^{60}}[/tex]

A = $1221

Correct choice: b. $1221.00

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

 (0.3672 , 0.7328)

Step-by-step explanation:

Explanation:-

Given Random sample size n =40

Sample proportion

                            [tex]p = \frac{x}{n} = \frac{22}{40} = 0.55[/tex]

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

          [tex](p-Z_{\alpha } \sqrt{\frac{pq}{n} } , p + Z_{\alpha } \sqrt{\frac{pq}{n} } )[/tex]

The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

    [tex](0.55-2.326\sqrt{\frac{0.55 X0.45}{40} } , 0.55 + 2.326\sqrt{\frac{0.55 X0.45}{40} } )[/tex]

  ( 0.55 - 0.1828 , 0.55 + 0.1828)

  (0.3672 , 0.7328)

Answer:

Step-by-step explanation:

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326

Answer:

The rate of simple interest for loan was 8%

Step-by-step explanation:

Given

Principal amount = p = $6200

Time = t = 1 year

Amount after interest = $6696

We have to calculate the amount of interest first

So,

Interest amount =I= Amount after interest - principal amount

= 6696-6200

=$496

The formula for simple interest is:

The rate of simple interest for loan was 8%

Step-by-step explanation:

Since line NL is not necessarily congruent to MQ (labelled with different congruent marks), triangle NLM is not congruent to triangle MQP.

Instead, triangles NLM and QPM are congruent.

This could true because of the markings of the triangles' sides and angles are in the same location.

But the statement labeled the lines wrong which makes them False
