Solve for x.
-7/8x=-5
Ox= 4 3/8
Ox=-4 3/8
Ox=5 5/7

Help please

#5 = 1

Because you have to find x of (-3) and then you find 1.

#6 = 1

The vertical line doesn't represent a function but horizontal line if passed once represents the function.

#7 = 4

You can just plug in the x values into the equation and solve for y and math the answer to the y data.

1) Choice 1, is the correct answer because -3 on the x-axis touches the graph at 6 on the y-axis.

2) Choice 2, is the correct answer. It doesn't pass the horizontal line because it passes through more than one line on the graph. However, it does pass the vertical line test, which only passes through one line and makes this graph a function.

3) Choice 4, is the correct answer. If you use an online graphing tool, you can match up the points on one of these tables. Choice 4 only seems to fit all on these into f(x) = -2x + 6 equation.

Hope this helps :)

Answer:

The 99% confidence interval for the true mean number of reproductions per hour for the virus is between 3.8 and 4.2.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.575\frac{2.3}{\sqrt{1083}} = 0.18[/tex]

Rounding to one decimal place, 0.2.

The lower end of the interval is the sample mean subtracted by M. So it is 4 - 0.2 = 3.8 reproductions

The upper end of the interval is the sample mean added to M. So it is 4 + 0.2 = 4.2 reproductions.

The 99% confidence interval for the true mean number of reproductions per hour for the virus is between 3.8 and 4.2.

Answer:

Current deposit amount  = $324.65 (Approx.)

Step-by-step explanation:

Given:

Cost of bicycle = $400

Future amount = $400

Rate of interest = 11% = 0.11

Number of year = 2 year

Find:

Current deposit amount

Computation:

Compound interest formula

A = P[1+r]ⁿ

Future amount = Current deposit[1+Rate of interest]ⁿ

400 = Current deposit[1+0.11]²

400 = Current deposit[1.11]²

400 = Current deposit[1.2321]

Current deposit amount  = 400 /1.2321

Current deposit amount  = $324.65 (Approx.)

Answer:

Kela will be able to travel for 7 stops before her money runs out.

Step-by-step explanation:

Since Kela wants to visit a friend who lives 8 kilometers away, and she'll ride the subway as she can before walking the rest of the way, and she needs to buy an access pass that costs $ 5.50 and there is also a fee of $ 1.25 for each stop, if Kela doesn't want to spend more than $ 15 on the trip, to determine the largest number of stops she can afford, the following calculation must be performed:

(15 - 5.5) / 1.25 = X

9.5 / 1.25 = X

7.6 = X

Therefore, Kela will be able to travel for 7 stops before her money runs out.

Answer:

The slope is -1/2

Step-by-step explanation:

The Y-intercept is (0,6)

Answer:

Confidence interval: (21.9, 32.9).

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 26 - 1 = 25

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 25 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.485

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.485\frac{11.2}{\sqrt{26}} = 5.5[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 27.4 - 5.5 = 21.9 hours

The upper end of the interval is the sample mean added to M. So it is 27.4 + 5.5 = 32.9 hours

Confidence interval: (21.9, 32.9).

Answer:

48 π

Step-by-step explanation:

Area of Circle =πr∧2

Big Circle Area = π(8)∧2 = 64π

Small Circle Area =π(4)∧2= 16π

Shaded Region = 64π - 16π = 48π

Answer:

x= 29

Step-by-step explanation:

The arc length will be option B. 13.6 cm.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

If radius of the circle is of r units, then

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

The superscript 'c' shows the angle measured in radians.

Given; A sector has a radius of 12 centimeters and an angle of 65 degrees.

So we input our values in the formula:

2π (12) x 65/360

= 24π x 65/360

= 13.6

Hence, the arc length will be option B. 13.6 cm.

Answer:

10 g

Step-by-step explanation:

40/2 = 20 g

20/2 = 10 g

If half-life of a radioactive kind of tellurium is 2 months. If you start with 40 grams of it, then 10 gm of it left after 4 months.

Half-life is the time required for a quantity to reduce to half of its initial value.

Given,

The half-life of a radioactive kind of tellurium is 2 months

It started with 40 grams of radioactive kind of tellurium

As given, half is for two months

In first two months it becomes 20 gm

40/2= 20gm

In second two months the 20 gm is reduced by half

20 gm/2=10gm.

Hence, 10gm of radioactive kind of tellurium is left after 4 months.
