Dennis drew the line of best fit on the scatter plot shown below:

What is the approximate equation of this line of best fit in slope-intercept form?
y = −15x + 2/3
y = -2/3 x + 15
y = −15x + 3/2
y = -3/2 x + 15

Answer:

D 133 degrees

Step-by-step explanation:

The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2

47  = [ (360 - x) - x ] / 2

94 = 360 - 2x

x = 133 degrees of the arc

The expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle whose side lengths measures are (2x+2) ft, (x+3) ft, and n ft.

If we take the first two sides are (2x+2) ft, (x+3) ft, and third is n ft.

By the triangle property, that sum of the two sides is always greater than the third side.

2x+2+x+3 > n

3x+5 > n  .....(1)

Now take first two sides as n ft, (x+3) ft, and third side (2x+2) ft

n+x+3 > 2x+2

n > x-1 .....(2)

From the inequality (1) and (2), we get:

x – 1 < n < 3x + 5

Thus, the expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.

The coin will land 7 times tail based on the experimental probability.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

When the coin tossed 45 times.

Head= 24, tail = 21

So, fraction of appearing tail will be

= 21 / 45

= 0.466667

Now, if the coin tossed 15 times then the coin land on tails

= 15 x 0.466667

= 7

Answer:

The flight was 137.45 miles farther than the direct path.

(make slight changes if directions were given on how to round. This is to the nearest hundredth)

Step-by-step explanation:

Use the Law of Cosines.

c^2=

a^2+b^2-2abcosC

You know two sides and the angle in between. The Law of Cosines will give us the third side.

The third side is the direct path of the airplane. We'll add the two other given sides to find the detour route that they took instead.

Then subtract the smaller number (direct route) from the actual route. See image.

The required equation is y = 10000(1.0.25)^2x. The value of Christina’s investment after 20 years is $30,773.14

Compound interest

The interest accrued on a sum of money is known as interest. The formula for calculating the compound interest is expressed as:

y = y0(1+r/n)^nx

where

x is the time taken

r is the rate in decimal

n is the compounding time

Given the following

x = 20 years

n  2(semi annually)

r  = 5.7% = 0.057

Substitute

y = 10000(1+0.057/2)^2(20)
y = 10,000(1 + 0.0285)^40

y = 10000(1.0285)^40
y = 30,773.14

Hence the value of Christina’s investment after 20 years is $30,773.14

The product of 960 and 1.0 x 106 expressed in scientific notation is 9.6 x 10^8.

The product of 960 and 1.0 x 10⁶ expressed in scientific notation is 9.6 x 10⁸.

To express the product of 960 and 1.0 x 10⁶ in scientific notation, we first perform the multiplication:

960 x 1.0 x 10⁶

= 960 x 10⁶

= 960,000,000

Since the result is greater than 1, but less than 10, we need to express it as a number between 1 and 10 multiplied by a power of 10.

In this case, we can express 960,000,000 as 9.6 x 10⁸.

Therefore, the product of 960 and 1.0 x 10⁶ expressed in scientific notation is 9.6 x 10⁸.

This notation represents a number that is 9.6 times 10 raised to the power of 8. It is a compact and convenient way to represent large numbers, especially in scientific and engineering contexts, where large quantities are common.

Step-by-step explanation:

2(6-2x)-2x=2(5+x)-4

Rearrange terms,

2(6-2x)-2x=2(5+x)-4

2(-2x+6)-2x=2(5+x)-4

Distribute,

2(-2x+6)-2x=2(5+x)-4

-4x+12-2x=2(5+x)-4

Combine like terms,

-4x+12-2x=2(5+x)-4

-6x+12=2(5+x)-4

Rearrange terms,

-6x+12=2(5+x)-4

-6x+12=2(x+5)-4

Distribute,

-6x+12=2(x+5)-4

-6x+12=2x+10-4

Subtract the numbers,

-6x+12=2x+10-4

-6x+12=2x+6

Subtract 12 from both sides,

-6x+12=2x+6

-6x+12-12=2x+6-12

-6x=2x+6-12

-6x=2x-6

Subtract 2x from both sides,

-6x=2x-6

-6x-2x=2x-6-2x

-8x=2x-6-2x

-8x=-6

Divide both sides by the same factor ( -8),

-8x/-8=-6/-8

x=-6/-8

Answer:

96.90

Step-by-step explanation:

850  *  .019  *  6   =

  This is simple interest ( no compounding interest)

Answer:

$96.90

Step-by-step explanation:

Let's find 1.9% of our amount, which is $850.

1% of 850 = 8.5

we need to get 1.9%, so lets multiply our current 1 percent by 1.9, to get what 1.9% would be.

1% of 850 = 8.5

x1.9 x1.9

1.9% = 8.5 x 1.9

1.9% = $16.15

This means that every year, the savings account gains $16.15 in interest. However, this doesn't account for all 6 years. So we multiply 16.15 by 6, for the 6 years that the money is in the saving account for.

$16.15 x 6 = $96.90 !

So, the total interest is $96.90 :)
