Use the excerpt to answer the question. As Melanie climbed down into the 2 points rowboat, Gina scooted over on the bench to make room for her. "We have to pick up Jacob now," Gina said, handing Melanie one of the oars. “And we should hurry so we can be long gone before the patrol barge comes by." Gina hadn't told Mom where she was going. Her mother had been smoothing a washcloth over Brandon's forehead as Gina had headed out. When her mother had asked where she was off to, Gina had tossed out some vague explanation. It was better for Mom not to worry. She had enough to worry about these days. They all did. Which statement conveys the main idea of the excerpt?
Gina, Melanie, and Jacob are worried to leave Brandon when they take their rowboat out because they know his mother has been fussing over him a lot lately.
Gina and Melanie need to get Jacob before they are caught, and Gina doesn't want her mother to know where she is going so as not to worry her.
Gina's mom is worrying about her and Melanie because they are going to pick up Jacob in their rowboat.
Jacob is missing, and his friends Melanie and Gina decide to go looking for him without telling anyone
Answer:

Construct the indicated confidence interval for the population mean using the t-distribution. Assume the population is normally distributed.
picture of question below
Using the t-distribution, it is found that the confidence interval is (14.2, 14.8).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 18 - 1 = 17 df, is t = 2.1098.
The other parameters are given by:
[tex]\overline{x} = 14.5, s = 0.68, n = 18[/tex].
Hence, the bounds of the interval are given by:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 14.5 - 2.1098\frac{0.68}{\sqrt{18}} = 14.2[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 14.5 + 2.1098\frac{0.68}{\sqrt{18}} = 14.8[/tex]
The confidence interval is (14.2, 14.8).

Multiply.
12x^4 (-5/6x^3y^2)
Answer:
-10[tex]x^{7}[/tex][tex]y^{2}[/tex]
Step-by-step explanation:
12[tex]x^{4}[/tex]([tex]-\frac{5}{6} x^{3}[/tex][tex]y^{2}[/tex])
First multiply 12 * - [tex]\frac{5}{6}[/tex] , solving this you get -10
Next multiply [tex]x^{4}[/tex] by [tex]x^{3}[/tex] , solving this you get [tex]x^{7}[/tex]
Finally you have [tex]y^{2}[/tex], and nothing to multiply it by. So it stays as [tex]y^{2}[/tex]
Put is all together and you get -10[tex]x^{7}[/tex][tex]y^{2}[/tex]

What are Supplementary Angles and Complementary Angles?If the sum of two angles equal 90°, they are complementary angles.
If the sum of two angles equal 180°, they are supplementary angles.
Given square CDFG:
a. Two pairs of angles that are complementary are: ∠DCM and ∠DMC; ∠MGF and ∠GMF
b. m∠GMF + m∠CMG + m∠DMC = 180° (angles on a straight line)

Determine the finance charge on a $6,800 car loan if monthly payments were $158.50 for 48 months.
Answer:
808
Step-by-step explanation:
Plan
You make 48 payments of 158.50. That gives you the total of what you have paid back.
Equation
Total payment = months * monthly payments
Solution
Total Payment = 48 * 158.50
Total Payment = 7608
Cost of the loan
Finance charge = amount paid - amount loaned
Finance charge = ?
amount paid = 7608
amount loaned = 6800
Finance charge = 7608 - 6800
Answer: Finance charge = 808
3. Amy Schorling is age 24 and is unmarried. She uses her vehicle
for business. Her driver-rating factor is 1.85. Her vehicle is
classified D-14. Her insurance consists of $25,000 property
damage, 25/50 bodily injury, $50-deductible comprehensive, an
no collision coverage.
a. What is her annual premium?
b. How much is her annual premium if she includes
$50-deductible collision coverage?
Based on Amy Schorling's driver rating factor, vehicle classification and bodily injury coverage, her annual premium is $576.46.
If she includes the $50-deductibel collision coverage, her insurance premium becomes $1,067.08.
How much is Amy Schorling's annual premium?At $25,000 property damage, her 25/50 bodily injury coverage premium is $206.40.
This should be added to her $50 comprehensive deductible D-14 vehicle classification of $105.20.
Annual base premium:
= 206.40 + 105.20
= $311.60
Annual premium:
= Annual base premium x Driver rating factor
= 311.60 x 1.85
= $576.46
How much is the annual premium including collision coverage?The annual base premium becomes:
= 311.60 + 265.20
= $576.80
Annual premium becomes:
= 576.80 x 1.85
= $1,067.08

Answer:
Step-by-step explanation:
for number 8 we have to use the equation πr^2, so plugging 9 into the equation would give us π(9^2). squaring the 9 gives us 81, and 81 times π equals ~25.
for number 9 we need to use the same equation, πr^2 to find the area, but since we are given the diameter we do not need to use r^2. Instead, we can use π(106) which gives us 333.

You are hired as a scrap metal dealer. A customer wants to sell you a piece of precious scrap metal. You know it is one of these
common metals. You slowly heat the metal and it melts at 962 °C. You also take the density of the metal and find it to be roughly

Silver 961.78oC 10.501
Gold 1064.18oC 19.282
density is the mass per unit volume. Melting point is determined by the intermolecular forces between particles in the solids.
We have been asked to find which cube weighs the most
density = mass/volume
when volume is constant for all the metals, then density is directly proportional to mass. Therefore metal with highest density has the highest mass.
from the given metals, metal with highest density is Gold.
correct answer is Gold.

Endeye needs to split 1/5 of the dinner left over from last week to feed her 3 siblings. What fraction of the original dinner will each sibling have to eat tonight?
Answer:
They each had 1/20 of the original meal
Step-by-step explanation:
To begin, there are 4 people. Her siblings, and herself. She is splitting the 1/5 leftover to feed them. To do this, we simply take 1/5 and put it into a fraction to get 0.2. Next, we can put 0.2 / 4 into a calculator to get how much each person can get.
0.2 / 4 = 0.05.
Now, we need to turn it into a fraction to find out how much they had in fraction form of the original.
0.05 = 1/20
They each had 1/20 of the original meal

Find the least common denominator (LCD) 8/9 and 4/5
Answer:
45
Step-by-step explanation:
First we write the first 10 multiples of 9 (the first denominator) :
9,18,27,36,45,54,63,72,81,90
Now we write the first 10 multiples of 5 (the second denominator) :
5,10,15,20,25,30,35,40,45,50
As we can see 45 is the lowest number that appears in both list.
Therefore 45 is the LCD of 8/9 and 4/5
Answer:
45
Step-by-step explanation:
So since we are finding the LCD, we only look at the denominators, 9 and 5.
We can count until we find the denominator:
[tex]9,18,27,36,45\\5,10,15,20,25,30,35,40,45[/tex]
So the LCD would be 45.

3x - 4y = -29
and
6x + 5y = -32
Answer:
x=-7,y=2
Step-by-step explanation:
3x - 4y = - 29
and 6x + 5y = - 32
3x - 4y = - 29 (1)
6x + 5y = -32 (2)
equation (1) x 2
6x-8y = -58
equation (2) × 1
6x + 5y = - 32
Substracting → - 13y = -26
13y = 26.
26/ 13 ⇒ y =
⇒ yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy = 2
Putting y = 2 in equation (1), we have
3x - 4(2) = - 20
→ 3x = -29 +8
→3x = -21
→ X = -7
x = - 7
