Answer:

f(x)=-75

Step-by-step explanation:

since f(x) varies directly with x

it implies that f(x)=Kx

k=f(x)/x

when f(x)=50 and x=-10

k=50/-10

k=-5

but when x=15, f(x)=-5×15

f(x)=-75

Here's the sentence in an equation: 2 = 6(x + 5)

Testing the hypothesis for the proportion, it is found that:

a) H0: p ≤ 0.50; HA: p > 0.50

b) The sample proportion is [tex]\pi = 0.6333[/tex].

c) The test statistic is [tex]z = 2.07[/tex].

d) The p-value of the test is of 0.0192.

e) Reject H0; the politician’s claim is supported by the data.

Item a:

At the null hypothesis, we test that the politician does not have the majority, thus:

[tex]H_0: p \leq 0.5[/tex]

At the alternative hypothesis, we test that he/she does have the majority, thus:

[tex]H_1: p > 0.5[/tex]

Item b:

38 out of 60, thus:

[tex]\pi = \frac{38}{60} = 0.6333[/tex]

The sample proportion is [tex]\pi = 0.6333[/tex].

Item c:

The test statistic is:

[tex]z = \frac{\pi - p}{\sqrt{\frac{p(1 - p)}{n}}}[/tex]

For this problem, [tex]\pi = 0.6333, p = 0.5, n = 60[/tex], thus:

[tex]z = \frac{0.6333 - 0.5}{\sqrt{\frac{0.5(0.5)}{60}}}[/tex]

[tex]z = 2.07[/tex]

The test statistic is [tex]z = 2.07[/tex].

Item d:

The p-value of the test is the probability of finding a sample proportion above 0.6333, which is 1 subtracted by the p-value of z = 2.07.

Looking at the z-table, z = 2.07 has a p-value of 0.9808.

1 - 0.9808 = 0.0192

The p-value of the test is of 0.0192.

Item e:

The p-value of the test is of 0.0192 < 0.05, thus, his claim is supported by the data, and we reject the null hypothesis. Then, the correct option is:

Reject H0; the politician’s claim is supported by the data.

The original size of the bottle is 17.5 ounces.

The soap manufacturer has increased the size of his bottles. This means that 18.4 ounce bottle is bigger than the original size of the bottle. The bottle was increased by 5%, this means that the new bottle is 105% (100% + 5%) bigger than the initial size of the bottle.

To determine the original size of the bottle, this formula would be used:

New bottle size / total percentage increase in the bottle  =   initial size of the bottle

18.4 / 1.05 = 17.5 ounces

Answer:

  D

Step-by-step explanation:

The absolute value function has its vertex at (1, 3). It is scaled by a factor of -2, so its transformation of the parent function f(x) = |x| will be ...

  -2f(x -1) +3 = -2|x -1| +3

This represents the left side of the equation you're seeking.

The right side equation is the equation of a line with slope 2/5 and y-intercept -2.2 = -11/5.

The equation that has both the left side and the right side correct is ...

  D.  -2|x -1| +3 = 2/5x -11/5

Answer:

F(x)=3^5(1/4)^x

Step-by-step explanation:

By the exponential decay definition: y = ab×

b determines the rate at which the graph grows: if b > 1, the function will increase. if 0 < b < 1, the function will decrease.

There is only (1/4)ˣ :  where 0<1/4<1 fit the definition, so F(x)=3^5(1/4)^x is the choice

----------------------------------------------------------------------------------------------------------

But.. look at the table attached, the f(x)=3(1.7)^-2x and F(x)=3^5(2)^-x also showed pattern of decay. It can verified from their graphs. (Try plot it with your calculator)

Answer:

y = -[tex]\frac{2}{8}[/tex] + 5

Step-by-step explanation:

You have all that you need

(y = mx+b, m= rise/run which is the change in y/change in x, b = y-intercept.)

so now we just need to put it to use!

      Let's take y = mx + b and break it into two parts. We need the b and the m. The b is easier, because we can conclude by looking at the graph it is equal too 5. Here is our equation so far:

y = mx + 5

Now we need to solve for m:

[tex]\frac{rise}{run} = \frac{2}{8}[/tex]

The line is going dowards, so the slope (m) is negative.

Here is our final answer:

y = -[tex]\frac{2}{8}[/tex] + 5

Answer:

9/32 or 0.28125

Step-by-step explanation:

8 parents and 4 teachers

There are 12 possible outcomes.

probability = # of favorable outcomes / # of possible outcomes

Let's do the teachers first.

There are 4 teachers, and we are finding the probability for 3 of them being picked.

Therefore,

P = 3/4

Now let's do the parents.

There are 8 parents, and we want 3.

Therefore,

P = 3/8

Now, we do  [tex]\frac{3}{4} *\frac{3}{8} = \frac{9}{32}[/tex]

Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.

Hope this helped!
