Slope = 5

Interpretation = Andre is saving 5 dollars per week

================================================

Work Shown:

The two points (0,40) and (4,60) are on the line

Use the slope formula

m = (y2-y1)/(x2-x1)

m = (60-40)/(4-0)

m = 20/4

m = 5

The slope is 5.

In this context, it means each time the number of weeks goes up by 1, the amount of his savings goes up by 5. In short, he's saving $5 per week.

note: the y intercept tells us that Andre started off with $40 in his account.

The slope is 5 in  slope-intercept form.

What is in slope-intercept form?

the y intercept tells us that Andre started off with $40 in his account.

Slope = 5

The two points (0,40) and (8,80) are on the line

Use the slope formula

Take any two points

m = (y2-y1)/(x2-x1)

= 80-40/8-0

= 40/8

=5

The slope is 5.

In this context, it means each time the number of weeks goes up by 1, the amount of his savings goes up by 5. In short, he's saving $5 per week.

Answer: 24

Step-by-step explanation: negative multiples by a negative is a positive

The opposite of -(-24) is -24.

A number is additive inverse of a given number when sum of the two number is zero and a number is a multiplicative inverse of a given number when product of two number is 1.

According to the given question statement we have to determine what is opposite of -(-24).

We know opposite of two numbers sums to zero.

Given -(-24).              ( negative signs will distribute and it'll become 24).

Let the opposite number be x.

∴ 24 + x = 0

x = -24.

So the opposite of -(-24) is - 24.

Answer:

The equation is y = 2x² + 7x + 5

Step-by-step explanation:

In the quadratic equation y = ax² + bx + c

∵ The sum of the roots is [tex]\frac{-7}{2}[/tex]

∵ The product of the roots is [tex]\frac{5}{2}[/tex]

→ By using the rules above

∴ [tex]\frac{-b}{a}[/tex] = [tex]\frac{-7}{2}[/tex]

∴ [tex]\frac{c}{a}[/tex] = [tex]\frac{5}{2}[/tex]

→ Compare between them

∴ a = 2

∴ -b = -7 ⇒ divide both sides by -1

∴ b = 7

∴ c = 5

∵ The form of the quadratic function is y = ax² + bx + c

→ Substitute the values of a, b, and c in it

∴ y = 2x² + 7x + 5

∴ The equation is y = 2x² + 7x + 5

Answer:

The 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).

Step-by-step explanation:

The information provided is as follows:

[tex]x=507\\n=32601\\\text{Confidence level }=99\%[/tex]

The sample proportion is:

[tex]\hat p=\frac{x}{n}=\frac{507}{32601}=0.016[/tex]

The critical value of z for 99% confidence level is, z = 2.56.

Compute the 99% confidence interval for the proportion of ASD in Arizona as follows:

[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

    [tex]=0.016\pm 2.58\cdot\sqrt{\frac{0.016(1-0.016)}{32601}}\\\\=0.016\pm 0.0018\\\\=(0.0142, 0.0178)\\\\\approx (0.014, 0.018)[/tex]

Thus, the 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).

x=8

Step-by-step explanation:

This is a congruent triangle. If we use Pythagorean theorm, we can see that 3^2+y^2=25

y^2= 16

y=4

(y is the base of the small triangle)

and since the big triangle and the small triangle are congruent(the ratios are the same), 3 is half of 6, and so the base of the small triangle is half of the big triangle's.

4*2=8

x=8

Answer:

3

Step-by-step explanation:

(x₁ , y₁) = (-1 , -2)   &    (x₂ , y₂) = (3 , 10)

[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4[/tex]

m  = 4

y - y₁ = m (x - x₁)

y - [-2] = 4(x - [-1])

y + 2 = 4(x + 1)

y + 2 = 4x + 4

    y = 4x + 4 - 2

    y = 4x + 2

[tex]t(n) = 1.89n[/tex]

Step-by-step explanation:

From the given information

i.e. p = 1.89

Therefore, the equation becomes

[tex]t(n) = pn[/tex]

as

[tex]p=1.89[/tex]

so

[tex]t(n) = 1.89n[/tex]

Verification:

If you want to purchase 1 pound apple

i.e.

[tex]n=1[/tex]

Total cost would be:

[tex]t(1) = 1.89 (1)[/tex]

t = $1.89 per pound

1) y=Mx+b

2) substitute the values: 0= -8x2 + b

3)multiply: 0= -16 +b

4) add 16 to both sides : 16= b

5) b is your y int. Plug in the values y=2x + 16

Answer : y= 2x+ 16

The scenario that could be represented by this graph is option: 3.

The rate of change of height represents the change in height with time.

Here, the given graph represents:

For some time the water level of the Humpy Dam doesn't change.

After a heavy rain spell, the water level rises, increasing at a constant rate.

After the rain subsides, it levels off again.

Here, the x-axis represents time and the y-axis represents the height of the water behind the dam.

The water height behind the dam was constant for a certain period. After rainfall, the height of the water increased at a constant rate. When the rain stopped, the water height behind the dam is constant at a newer height.
