x(85+1.90)=96.90 what is x ?????

Answers

Answer:

1.1150

Step-by-step explanation:

x(86.90) = 96.90

86.90x = 96.90

86.90x/86.90 = 96.90/86.90

x = 1.120

Answer:

[tex]\huge\boxed{\sf x = 1.12}[/tex]

Step-by-step explanation:

x (85 + 1.90) = 96.90

Add

x (86.90) = 96.90

Divide 86.90 to both sides

x = 96.90 / 86.90

x = 1.12

Darren wants to estimate the mean age in a population of trees. He'll sample nnn trees and build a 90\%90%90, percent confidence interval for the mean age. He doesn't want the margin of error to exceed 333 years. Preliminary data suggests that the standard deviation for the ages of trees in this population is \sigma=16σ=16sigma, equals, 16 years. Which of these is the smallest approximate sample size required to obtain the desired margin of error?

Answers

Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.

What is a z-distribution confidence interval?

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.

The margin of error is given by:

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

In this problem, we have that the parameters are given as follows:

[tex]M = 3, z = 1.645, \sigma = 16[/tex].

Hence, solving for n, we find the sample size.

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

[tex]3 = 1.645\frac{16}{\sqrt{n}}[/tex]

[tex]3\sqrt{n} = 1.645 \times 16[/tex]

[tex]\sqrt{n} = \frac{1.645 \times 16}{3}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2[/tex]

[tex]n = 76.97[/tex]

Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.

Matthew bought 16 gallons of gas for $4.25 per gallon. How much did he spend? Show your work.

Answers

Answer:

$68.00

Step-by-step explanation:

16 x 425 = 6800

Just move the decimal 2 places to the left to get 68

Matthew spends $68 on gas as the rate of gas is $4.25 per gallon.

What is per unit?

Per unit is a technique of expressing a quantity's value in terms of a base or reference quantity. Each system variable or quantity in a per-unit system is normalized in relation to its own base value.

Given Matthew bought 16 gallons of gas for $4.25 per gallon.

Since the price per gallon = 4.25

The price of the gas for 16 gallons = 4.25 * 16

The price of the gas for 16 gallons = 68.00

Therefore, Due to the $4.25 per gallon price, Matthew spends $68 on gas.

4. A punch bowl holds 80 oz of punch, that is enough for exactly 16 servings.
Hillary says that there are 20oz of punch for every 5 servings. Is Hillary correct?

Answers

Answer:

No, Hillary is incorrect. There's 20oz of punch for every 4 servings.

Step-by-step explanation:

80oz / 20oz = 4

16 servings / 4 = 4 servings

So, instead of there being 20oz of punch for every 5 servings, there would be 20oz of punch for every 4 servings.

Shannon needs 20g of 80% gold to make a pendant. She has some 85% gold and some 70% gold. How much of each should she use of each alloy, use two linear equations to solve

Answers

Answer:

85%: 13 1/3 grams70%: 6 2/3 grams

Step-by-step explanation:

Two equations can be written to describe the desired relationships. One can describe the total quantity of gold alloy needed. The other can describe the amount of gold in the combination of alloys.

Let x and y represent the quantities in grams of 85% and 70% gold alloy needed, respectively.

x + y = 20 . . . . . . Shannon needs a total of 20 grams

0.85x +0.70y = 0.80(20) . . . . . the amount of gold in the mix of alloys

These equations are often nicely solved by substitution. Substituting for y, we have ...

0.85x +0.70(20 -x) = 0.80(20)

0.15x = 0.10(20) . . . . . . . eliminate parentheses, subtract 0.70(20)

x = 40/3 = 13 1/3 . . . . . divide by 0.15

y = 20 -13 1/3 = 6 2/3

Shannon should use 13 1/3 grams of 85% alloy and 6 2/3 grams of 70% alloy.
