Which number line can be used to find the distance between (4, -1) and (8, -1)?
Answer:
I am not sure, but I believe it is the last one. Sorry if it's not right.
Answer:
The first number line
Step-by-step explanation:
Hey There!
The answer is the first number line because the y values in the given coordinates are the same so all we have to do is plot the x values (4 and 8) and we can find the distance between the two points. The first number line has 4 and 8 on it therefore that is the answer.
Find the sample size required to achieve the given margin of error with SD = 51.02 and z - score = 1.96. Round your answer to the nearest whole number. margin of error = 2
Answer:
The sample size required is 2500.
Step-by-step explanation:
z-score:
In function of the margin of error M, the z-score is given by:
[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}[/tex]
In this question, we have that:
[tex]\sigma = 51.02, M = 2, Z = 1.96[/tex]
So
[tex]Z = \frac{M\sqrt{n}}{\sigma}[/tex]
[tex]1.96 = \frac{2\sqrt{n}}{51.02}[/tex]
[tex]2\sqrt{n} = 51.02*1.96[/tex]
[tex]\sqrt{n} = \frac{51.02*1.96}{2}[/tex]
[tex](\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2[/tex]
[tex]n = 2500[/tex]
The sample size required is 2500.

7) My savings account increases in value by 4% every year. I started with
$10,000. Which of the following equations can be used to represent the
value of my account over time. *
f(x) = 10000(0.04)^x
f(x) = 10000(1 -0.04)^x
Of(x) = 10000(1.04)^x
O f(x) = 10000(0.96)*x
Answer: 10000(1.04)^x
Step-by-step explanation: every year your interest increases 4%
And you get multiplier 1.04. After first year you have 10400 and next year you multiply it by 1.04 again.

the bill comes out to 65.35 an the sales tax is 7.7% what is the total amount of the bill
Answer:
$70.38
Step-by-step explanation:
7.7% = 0.077
Since you are adding 7.7 percent to $65.35, you add a 1 to the decimal form of 7.7%, then multiply.
65.35 x 1.077 = 70.38
Answer:
The bill will come out to be $73.80
Step-by-step explanation:
Take the bill and divide it by the tax and you'll get 8.4
Add 8.4 to 65.35 and you'll get 73.80
very urgent, how many beans?
Answer: Well, my best guess would be: 1636 beans
apparently the average weight of a jellybean is 1.1 grams
1.8 kg is 1800 grams
1800 / 1.1 = around 1636
So it's around 1636 jelly beans ?

A rectangle has an area of 54 square inches and a length of 6 in what is the width in inches of the rectangle?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Areas and Volumes.
We know that, Area of a Rectangle = length * Width.
Since,here Length = 6 inch and Area = 54 square inches,
==> Width = Area / length
==> Width = 54/6
=> Width = 9 inches.
Hence the width of the rectangle is 9 inches.

I need help please with number 5 and 6
Answer: #5 = -3 #6 = 0, there is no x
Step-by-step explanation: #5 - first you have to turn it into slope-intercept form. So, 3y+12=-9x will become y= -3x -4 because you divide all sides by 3 and you transpose 12 so it becomes negative... then you will pick out you slope which is the number in front of x so slope = -3
#6 - the slope is zero because there is no x in that equation.
Can anyone help me I will really appreciate it.
Answer:
-9 = Yes
8 = Yes

Answer:
m = 1/2
Step-by-step explanation:
Find all possible values of a and b in the figures
below, given these three conditions:
1. The perimeters are equal.
2. The rectangle has an area
between 80 and 100 square units.
3. The values of a and b are integers
Answer:
Step-by-step explanation:
The perimeters are equal, so
2a+2b = 4a+b
b = 2a
area of rectangle is between 80 and 100
80 < ab < 100
substitution
80 < a(2a) < 100
40 < a² < 50
√40 < a < √50
6.4 < a < 7.1
Since a is an integer, a = 7.
b = 2a = 14.
Find an equation of the tangent line to the curve at the given point. y = x3 − 3x + 2, (3, 20)
Answer:
[tex]y - 20 = 24(x - 3)[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, has the following format:
[tex]y - y_0 = m(x - x_0)[/tex]
In which the point is [tex](x_0,y_0)[/tex] and the slope is m.
(3, 20)
This means that [tex]x_0 = 3, y_0 = 20[/tex]. So
[tex]y - y_0 = m(x - x_0)[/tex]
[tex]y - 20 = m(x - 3)[/tex]
Slope:
The slope is the derivative of the function at the point:
The function is:
[tex]y = x^3 - 3x + 2[/tex]
The derivative is:
[tex]y^{\prime}(x) = 3x^2 - 3[/tex]
At the point, we have that [tex]x = 3[/tex]. So
[tex]m = y^{\prime}(3) = 3*3^2 - 3 = 27 - 3 = 24[/tex]
So the equation to the tangent line to the curve a the point is:
[tex]y - 20 = 24(x - 3)[/tex]
The length of a rectangular garden is 4 less than twice the width find the perimeter and area of the garden
Answer:
Let w be the width. Then the length is 2w-4. So:
w(2w-4)=96
2w²-4w-96=0
w²-2w-48=0
(w-8)(w+6)=0
w=8 or -6
Throwing out the negative value for w, we get a width of 8 yds, and a length of 12 yds. ☺☺☺☺
