Which graph represents the solution set of the following situation? Andrew is buying fruit for a fruit salad. Bananas cost $1 a pound and oranges cost $2 a pound. He plans to buy at least 10 pounds of fruit and spend no more than $20. Let x represent pounds of bananas and let y represent pounds of oranges..
Answers
Answer:
[tex]x + y \ge 10[/tex]
[tex]x + 2y \le 20[/tex]
Step-by-step explanation:
The question is incomplete as the graphs are not shown. So, I will derive the inequalities and plot the graph.
Given
[tex]Banana = \$1[/tex]
[tex]Orange = \$ 2[/tex]
[tex]Purchase = 10lb[/tex] --- At least
[tex]Spedings = \$20[/tex] --- Not more than
And we have:
[tex]x = Banana; y = Orange[/tex]
The number of purchase will be represented as:
[tex]x + y \ge Purchase[/tex] ---- (at least)
[tex]x + y \ge 10[/tex]
The amount spent will be represented as;
[tex]1 * x + 2 * y \le 20[/tex] --- (not more than)
[tex]x + 2y \le 20[/tex]
So, the inequalities are:
[tex]x + y \ge 10[/tex]
[tex]x + 2y \le 20[/tex]

Answers
Answer:
[tex] \bf \large 60 \: m[/tex]
Step-by-step explanation:
Given that :The radius of a circle is 10 m.to find :Find the circumference to the nearest tenth.formulas used :circumference = 2 × π × rwhere,π = 22/7
r = 10 m
explanation :⟼ c = 2πr
⟼ c = 2 × 22/7 × 10 m
⟼ c = 2 × 3•14 × 10m
⟼ c = 6•28 × 10 m
⟼ c = 62•8 m
Round to the nearest tenth :⟼ c = 62•8 m
⟼ c = 60 m
∴ circle circumference is 60 m.
1. If the 3rd term of a geometric sequence is 1,000 and the 2nd term is 100, what is
the 1st term?
Answers
Answer: 10
Step-by-step explanation: If you do the 3rd term divided by the 2nd term, that gives you 10. So, if the 1st term is 10, you do 10 times 10 which is 100 (2nd term) and 100 times 10 which is 1,000 (3rd term).

Answers
Answer:
10 1/18
Step-by-step explanation:
3 2/6 + 8 2/9 - 1 1/2 = ?
First, we need to find the common denominator, which I will choose to be 18, which means I will need to convert all the fractions.
3 6/18 + 8 4/18 - 1 9/18 = ?
Now, we solve.
3 6/18 + 8 4/18 - 1 9/18 = 10 1/18

The brand manager for a brand of toothpaste must plan a campaign designed to increase brand recognition. He wants to first determine the percentage of adults who have heard of the brand. How many adults must he survey in order to be 95% confident that his estimate is within seven percentage points of the true population percentage? Complete parts (a) through (c) below.
a) Assume that nothing is known about the percentage of adults who have heard of the brand,
n= ____________ (Round up to the nearest integer.)
b) Assume that a recent survey suggests that about 81% of adults have heard of the brand.
n= ____________ (Round up to the nearest integer.) Please show work for this one because they change the percentage a lot, so I may have to work this part out myself. Thank you
c) Given that the required sample size is relatively small, cculd he simply survey the adults at the nearest college?
a. No, a sample of students at the nearest college is a cluster sample, not a simple random sample, so it is very possible that the results would not be representative of the population of adults.
b. Yes, a sample of students at the nearest college is a simple random sample, so the resuls should be representative of the population of adults.
c. No, a sample of students at the nearest college is a stratified sample, not a simple random sample, so it is very possible that the results would not be representaive of the population of adults.
d. No, a sample of students at the nearest college is a convenience sample, not a simple randmom sample. so it is very possible that the results would not be representative of the population of adults.
Answers
Answer:
Part A; n= 196
Part B: n = 120
Part C:
d. No, a sample of students at the nearest college is a convenience sample, not a simple random sample. so it is very possible that the results would not be representative of the population of adults.
Step-by-step explanation:
Part A;
The sample size n can be calculated by using the formula
p^ ± z∝/2* √pq/n
this implies that
e= z∝/2* √pq/n
where e= ║p-p^║= 0.07
p^= 0.5
q^= 0.5
Putting the values
e= z∝/2* √pq/n
0.07= ± 1.96 √0.5*0.5/n
Squaring both sides
0.0049 = 3.8146*0.25/n
n= 196
Part B:
Given p^= 0.81 and q^= 1-p^= 1-0.81= 0.19
e= 0.07
Using the formula
e= z∝/2* √pq/n
Putting the values
0.07= ± 1.96 √0.81*0.19/n
Squaring both sides
0.0049 = 3.8146*0.1539/n
n= 119.809= 120
Part C:
The sample selected is not a random sample because all the adults who have heard about the brand do not have equal chances of being chosen.
It is convenience sample that is it is chosen at ease from a nearby college.

E
Answers
Answer:
The hourly growth rate parameter is of 4.74%
Step-by-step explanation:
Continuous growth model:
The continuous growth model for a population after t hours is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial population and r is the hourly growth rate parameter, as a decimal.
A sample of 1500 bacteria selected from this population reached the size of 1805 bacteria in four hours.
This means that [tex]P(0) = 1500, P(t) = 1805, t = 4[/tex]
Find the hourly growth rate parameter.
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]1805 = 1500(1+r)^4[/tex]
[tex](1+r)^4 = \frac{1805}{1500}[/tex]
[tex]\sqrt[4]{(1+r)^4} = \sqrt[4]{\frac{1805}{1500}}[/tex]
[tex]1 + r = (\frac{1805}{1500})^{\frac{1}{4}}[/tex]
[tex]1 + r = 1.0474[/tex]
[tex]r = 0.0474[/tex]
0.0474*100% = 4.74%
The hourly growth rate parameter is of 4.74%

One sample t test
Step-by-step explanation:
A one proportion sample t test is employed when we intend to test the sample mean of a certain sample against a particular or specified population property . In the scenario above, we could use the information given to obtain the one sample proportion test statistic by using the formular :
Test statistic = (xbar - μ) ÷ (σ/sqrt(n))
Where, xbar = sample mean ;
μ = population mean
σ = population standard deviation
n = sample size
Using the test statistic, we can then obtain the Pvalue and compare to the specified α - level
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 22.4 pounds and a standard deviation of 5.8 pounds. Step 1 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 73 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.
Answers
Answer:
sampling distribution = 22.4
sampling deviation = 0.68
Step-by-step explanation:
Given that :
Mean , μ = 22.4
Standard deviation, σ = 5.8
n = 73
Therefore, the sampling distribution of the mean and the standard deviation is
[tex]$\mu_{\overline x} = 22.4$[/tex]
So, [tex]$\sigma_{\overline x}=\frac{\sigma}{\sqrt n}$[/tex]
[tex]$=\frac{5.8}{\sqrt {73}}$[/tex]
= 0.68
So the sampling distribution of the mean is 22.4
The standard deviation is 0.68
A stone is dropped from a 196-foot platform. Use the formula h=−16t2+v0t+196 to determine how many seconds it will take for the stone to hit the ground. (Since the stone is dropped, v0=0.) Round your answer to the nearest tenth.
Answers
The stone will hit the ground after 3.5 seconds.
Given information:
A stone is dropped from a 196-foot platform.
The height of the stone after t seconds is represented by [tex]h=-16t^2+v_0t+196[/tex]
As the stone hits the ground, the height will become zero and the initial velocity [tex]v_0[/tex] is equal to zero as it is dropped.
So, the time after which the stone will hit the ground will be calculated as,
[tex]h=-16t^2+v_0t+196\\0=-16t^2+0t+196\\16t^2=196\\t^2=12.25\\t=3.5[/tex]
Therefore, the stone will hit the ground after 3.5 seconds.
