When Joyce went to the store, she bought a 32-ounce jar of jelly, a 16-
ounce jar of pickles, and an 8-ounce tub of butter. About how many total
grams are the three items? (1 ounce = 28 grams)
Answer:
1568 grams
Step-by-step explanation:
32 x 28 = 896 ][ 16 x 28 = 448 ][ 8 x 28 = 224 ; 896 + 448 + 224 = 1568
Let X and Y denote the latitude and longitude of a person who is thought to be lost in a certain part of a forest. If we assume that the density of X is uniform for 2 < X < 8.2 and the density of Y is also uniform for 3.01 < Y < 6.3, and we assume that X and Y are independent, then the joint density of X and Y is
Answer:
P(X, Y) = 1/(20.398 ) if X ∈ (2, 8.2) and Y ∈ (3.01, 6.3)
P(X, Y) = 0 if X ∉ (2, 8.2) and Y ∉ (3.01, 6.3)
Step-by-step explanation:
We know that the possible values of X (all with the same probability) are:
2 < X < 8.2
And for Y we have the range (also uniform):
3.01 < Y < 6.3
Then we have a rectangle of area.
(8.2 - 2)*(6.3 - 3.01) = 20.398
Such that the probability for all the points inside the rectangle should be exactly equal, then we will have:
P(X, Y) = 1/(20.398 ) if X ∈ (2, 8.2) and Y ∈ (3.01, 6.3)
Such that if we integrate this in the given region, the integral will be equal to 1, as we should expect.
And zero if the point is outside that region, this is:
P(X, Y) = 0 if X ∉ (2, 8.2) and Y ∉ (3.01, 6.3)

Answer:
The area of the rectangle is 0.0875 sq ft.
Step-by-step explanation:
Given that,
The length of the rectangle, L = 0.35 feet
The breadth of the rectangle, B = 1/4 feet
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
[tex]A=\dfrac{1}{4}\times 0.35\\\\A=0.0875\ ft^2[/tex]
So, the area of the rectangle is 0.0875 sq feet.

Step-by-step explanation:
The probability that a birth in the United States is male during 2018 is 0.511. Suppose a random number generator from 1 to 1,000 is used as a statistical model to create simulated results for births in the United States during 2018. Suppose the numbers 1 to 511 represent a male birth in the United States during 2018 and 512 to 1,000 represent a female birth in the United States during 2018. Explain whether the following results are consistent with the model, and if not, explain the expected number of male births and the expected number of female births for 300
trials.
In 300
simulated trials, 171 of the births are female and 129 are male.
Answer:
Step-by-step explanation:
The probability that a birth in the United States is male during 2018 is 0.511. So there are slightly more males than females born.
In 300 simulated trials, 171 of the births are female and 129 are male. More females are born so it is not consistent with the model.
The expected number of male birth for 300 trials should be 300*0.511 = 153.
The expected number of female = 300-153 = 147
I need help with this!! What is the answer???!
Answer:
53
Step-by-step explanation:
Sum of interior angles of a pentagon = 540°
Therefore,
2x° +2x° + 3x° + 3x° + 10 = 540°
10x° + 10° = 540°
10x° = 540° - 10°
10x° = 530°
10x = 530
x = 530/10
x = 53

Question 1
Researchers want to find a way to increase the growth rate of corn so it can be harvested more often. To test the effectiveness of a new type of spray fertilizer, plants grown from 200 corn seeds were divided equally into two groups: a treatment group and a control group. The treatment group was frequently sprayed with the new type of fertilizer. The growth in centimeters of each corn plant was noted before and after the treatment.
The results showed that the mean change in the growth rate by the treatment group is 8 points more than that of the control group. To test whether the results could be explained by random chance, researchers created a table that summarizes the results of 1,000 re-randomizations of the data with differences of means rounded to the nearest 2 points.
Consider the significance level to be set at 5%, so results less than 5% can be considered statistically significant.
Part B
Question
Which statement is true about the result considering a significance level of 5%?
The result is not statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does not increase the growth rate.
The result is not statistically significant, which implies that this result could be due to random chance.
Answer: The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
Step-by-step explanation:
The statement that is true about the result considering a significance level of 5% is B. The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
What is Statistics?This refers to the analysis of numbers and data to make an inference about a thing.
Hence, we can see that based on the research made about the growth rate of corn, we can see that from the significance level of 5%, we can see that spraying the corn plants with the new type of fertilizer does increase the growth rate.

Answer:
735.6 in³
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = 4/3πr³ . . . . where r is the radius
The radius is half the diameter, so we can write this in terms of diameter as ...
V = (4/3)π(d/2)³ = (π/6)d³
Using the given diameter, the volume is ...
V = (π/6)(11.2 in)³ ≈ 735.6186 in³
The volume is about 735.6 cubic inches.
Timmy is building a new website. Right after he starts, he has 2 visitors. He expects his visitors to increase according to a model he developed for his other websites growth, v(t)=10t+b, where b is the number of visitors right afte he starts building his website, t is the time since he stgarted building his website in weeks and v(t) is the nunber of total visitors after t weeks.
How many visitors does he get 4 weeks after starting to build his website?
How any new visitors does he get per week?
Answer:
He gets 42 visitors 4 weeks after starting to build his website.
He gets 10 new visitors per week.
Step-by-step explanation:
Equation for the number of visitors:
The equation for the number of visitors Timmy's new website receives after t weeks is:
[tex]v(t) = 10t + b[/tex]
In which b is the number of visitors rightly after he starts.
Timmy is building a new website. Right after he starts, he has 2 visitors.
This means that [tex]b = 2[/tex], so:
[tex]v(t) = 10t + 2[/tex]
How many visitors does he get 4 weeks after starting to build his website?
This is v(4). So
[tex]v(4) = 10(4) + 2 = 40 + 2 = 42[/tex]
He gets 42 visitors 4 weeks after starting to build his website.
How any new visitors does he get per week?
After 0 weeks:
[tex]v(0) = 10(0) + 2 = 0 + 2 = 2[/tex]
After 1 week:
[tex]v(1) = 10(1) + 2 = 10 + 2 = 12[/tex]
2 weeks:
After 2 week:
[tex]v(2) = 10(2) + 2 = 20 + 2 = 22[/tex]
22 - 12 = 12 - 2 = 10
He gets 10 new visitors per week.

In a survey of 802 U.S. adult drivers, 265 state that traffic is getting worse in their community. Construct a 95% confidence interval for the proportion of residents who think traffic is getting worse in their community.
Answer:
The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
In a survey of 802 U.S. adult drivers, 265 state that traffic is getting worse in their community.
This means that [tex]n = 802, \pi = \frac{265}{802} = 0.3304[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 - 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.2978[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 + 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.3630[/tex]
The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).
