Answer:

Question 2: 4 1/2

Question 10: $7.24

Step-by-step explanation:

Question 2:

1 1/2/x = 3/9

to solve for x, we need to use 1 1/2/x and multiply it by x:

1 1/2/x * x

then we need to have 3/9 multiplied by x:

3/9 * x

this is equal to 1 1/2 = 3/9 * x

now you need to multiply both sides by the opposite of 3/9 = 9/3

3/2 * 9/3 = 3/9 * 9/3 * x which equals 9/2 = 4 1/2

final answer: 4 1/2

Question 10:

Jeff bought 3 boxes of cereal $2.99 each which comes up to $8.97,

he bought one gallon of milk for $4.98,

and 4 bananas for $0.50 each which in total is $2.00.

total amount spent: 8.97 + 4.98 + 2.00 = $15.95

We know there is a 20% off discount so what we have to do is take 20% off $15.95!

20%= $3.19

15.95 - 3.19 = 12.76

The total is now $12.76. But, Jeff payed with a $20.00 bill. Because of this, he will get $7.24 back. 12.76 + 7.24 = 20

Final answer: $7.24

The null hypothesis is μ≥700 and alternative hypothesis is μ<700, the type of test statistic is t statistic, the statistical test value is -2.650, the critical value is -1.796 and the null hypothesis is reject.

Given the average monthly rent for apartments on the east side of the cities is $700, and the mean for a random sample of 12-month rents for apartments on the east side is $687, with a standard deviation of $17.

Statistical hypothesis testing is an important technique in inferential statistics. Used to test hypotheses about population parameters. Statistical tests are used to compute test statistics and p-values. Finally, use this test statistic and the p-value to make a decision about rejecting the null hypothesis.

(a) Let μ be the population and monthly rent. the null and alternative hypotheses are given below.

Null Hypothesis: μ≥700

Alternative hypothesis: μ< 700 This is a left-sided hypothesis test.

(b) Here, the sample size is less than 30 and the population mean is unknown. Therefore, a one-sample t-test can be used here. Therefore, the t statistic is the test statistic.

(c) Given [tex]\bar{x}[/tex]=687, s=17 and n=12, the test statistic is computed as

[tex]\begin{aligned}t&=\frac{\bar{x}-\mu_{0}}{s/\sqrt{n}}\\ &=\frac{687-700}{17/\sqrt{12}}\\ &=-2.64901888216\\ &=-2.650\end[/tex]

(d) For n-1=12-1=11 degrees of freedom

The critical value for a significance level of 0.05 with 11 degrees of freedom is

[tex]\begin{aligned}t_{crit}&=-1.7959\\ &=-1.796\end[/tex]

(e) Reject the null hypothesis because the statistical test value (-2.650) is less than the critical value (-1.796). There is ample evidence to support the claim that the average monthly rent for East Side apartments is lower than stated on the website.

Hence, The value of test statistic and critical value has a mean of $687 and a standard deviation of $17, which are -2.650 and -1.796.

Answer: x = [tex]\sqrt{y^2 -1}[/tex]

Step-by-step explanation:

The values of x and y are 19 and 14 respectively.

Given the hypotenuse = 24

Opposite = x

Adjacent = y

Let's use the sine ratio to find the opposite side

sin of angle = opposite/hypotenuse

sin 54 = x/24

Cross multiplysin 54 × 24 ,= x

x = 19.42

x = 19

To find the adjacent side, we use cosine ratio

cos = adjacent/hypotenuse

cos 54 = y/25

Cross multiply

cos 54 × 24 = y

y = 14

Thus, the values of x and y are 19 and 14 respectively.

The equation of the function d(t) is d(t) = -2sin(π/2 t) + 5

The function is given as:

d(t) = a * sin(b * t) + d

The bob is 5 cm away from the wall implies that the vertical shift is 5.

This means that

d = 5

So, we have

d(t) = a * sin(b * t) + 5

The bob reaches the closest point to the wall, which is 3 cm from the wall.

So, the amplitude is

A = 3 - 5

Evaluate

A= -2

So, we have:

d(t) = -2 * sin(b * t) + 5

The period is calculated as:

B = 2π/t

Where

t = (5 + 3)/2

This gives

t = 4

Substitute t = 4 in B = 2π/t

B = 2π/4

Evaluate

B = π/2

So, we have:

d(t) = -2sin(π/2 t) + 5

Hence, the equation of the function d(t) is d(t) = -2sin(π/2 t) + 5

(-4,0) and (4,0)

Step-by-step explanation:

The x-intercepts occur for values of x where f(x) = 0.

f(x) = 0 when the nominator ([tex]x^{2} - 16[/tex]) = 0.

[tex]x^{2} -16[/tex] is a difference of squares,
so you can factor it as (x + 4)(x – 4)

When x = –4 or x = 4, the nominator is 0, and f(x) = 0

Mr. Cahn’s total earnings in a year is $18,900.

The total earnings is a function of the annual salary, commission and Christmas bonus.

Total earnings = annual salary + commission + Christmas bonus

Commission = 6% x (160,000 - 20,000)

6% x $140,000

0.06 x 140,000 =  $8,400

Total earnings =  $8,400 + 10,000 + $500 = $18,900

Answer: 10

Step-by-step explanation:

Since exactly 1 in every $n$ consecutive dates is divisible by $n$, the month with the fewest relatively prime days is the month with the greatest number of distinct small prime divisors. This reasoning gives us June ($6=2\cdot3$) and December ($12=2^2\cdot3$). December, however, has one more relatively prime day, namely December 31, than does June, which has only 30 days. Therefore, June has the fewest relatively prime days. To count how many relatively prime days June has, we must count the number of days that are divisible neither by 2 nor by 3. Out of its 30 days, $\frac{30}{2}=15$ are divisible by 2 and $\frac{30}{3}=10$ are divisible by 3. We are double counting the number of days that are divisible by 6, $\frac{30}{6}=5$ days. Thus, June has $30-(15+10-5)=30-20=\boxed{10}$ relatively prime days.

Given that Eli ate one third of a pie on friday, one fourth of the pie on saturday, and final 50 ounces of the pie on sunday which is left out.

We have to find the amount of pie that she ate one saturday.

We are given fraction and we know that sum of all fractions of something is equal to 1.

Let the proportion that she ate on sunday be x.

1/3+1/4+x=1

Taking LCM.

(4+3+12x)/12=1

7+12x=12

12x=12-7

12x=5

x=5/12

So the left out out portion that she ate on sunday is 5/12 of the pie.

We are given that she ate 50 ounces on sunday so the total pie will be 12/5*50=120 ounces.

Portion eaten by Eli on saturday =1/4

Pie that she ate on saturday=1/4*120
