A water tank has a square base of area 5 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, starting at t=0, at the rate of 2 + 4 t cubic meters per hour. Here t is the time in hours. What is the depth of water remaining in the tank after 3 hours
Answer:
[tex]9.2\ \text{m}[/tex]
Step-by-step explanation:
[tex]b[/tex] = Surface area of base = 5 square meters
Volume of water in tank = 70 cubic meters
The rate at which the volume is reducing is
[tex]\dfrac{dV}{dt}=2+4t\\\Rightarrow dV=2+4tdt[/tex]
Integrating from [tex]t=0[/tex] to [tex]t=3[/tex]
[tex]V=\int^3_0(2+4t)dt\\\Rightarrow V=2t+2t^2|_0^3\\\Rightarrow V=2\times 3+2\times 3^2-0\\\Rightarrow V=24[/tex]
Volume of water remaining in the tank is [tex]70-24=46\ \text{m}^3[/tex]
Suface area of base [tex]\times[/tex] depth = Volume
[tex]5\times d=46\\\Rightarrow d=\dfrac{46}{5}\\\Rightarrow d=9.2\ \text{m}[/tex]
The depth of the water remaining in the tank is [tex]9.2\ \text{m}[/tex].

Step-by-step explanation:
Three students, Linda, Tuan, and Javier, are given five laboratory rats each for a nutritional experiment. Each rat's weight is recorded in grams. Linda feeds her rats Formula A, Tuan feeds his rats Formula B, and Javier feeds his rats Formula C. At the end of a specified time period, each rat is weighed again, and the net gain in grams is recorded. Using a significance level of 10%, test the hypothesis that the three formulas produce the same mean weight gain.
Linda's rats Tuan's rats Javier's rats
43.5 47.0 51.2
39.4 40.5 40.9
41.3 38.9 37.9
46.0 46.3 45.0
38.2 44.2 48.6
Determine whether or not the variance in weight gain is statistically the same among Javier’s and Linda’s rats. Test at a significance level of 10%.
Answer:
The variance in weight is statistically the same among Javier's and Linda's rats
The null hypothesis will be accepted because the P-value (0.53 ) > ∝ ( level of significance )
Step-by-step explanation:
considering the null hypothesis that there is no difference between the weights of the rats, we will test the weight gain of the rats at 10% significance level with the use of Ti-83 calculator
The results from the One- way ANOVA ( Numerator )
with the use of Ti-83 calculator
F = .66853
p = .53054
Factor
df = 2 ( degree of freedom )
SS = 23.212
MS = 11.606
Results from One-way Anova ( denominator )
Ms = 11.606
Error
df = 12 ( degree of freedom )
SS = 208.324
MS = 17.3603
Sxp = 4.16657
where : test statistic = 0.6685
p-value = 0.53
level of significance ( ∝ ) = 0.10
The null hypothesis will be accepted because the P-value (0.53 ) > ∝
where Null hypothesis H0 = ∪1 = ∪2 = ∪3
hence The variance in weight is statistically the same among Javier's and Linda's rats
Hayden wanted to investigate whether there was a difference in the time spent in the checkout line between two grocery stores. She went to Safeway on a Tuesday morning and recorded the time, in minutes, it took 30 customers to go through a checkout line. Then she went to Whole Foods on Tuesday afternoon and recorded the time it took 30 customers to go through a checkout line. Hayden calculated the mean number of minutes for the customers in each line. She intends to conduct a two-sample t-test for a difference in means between the two stores. Have all conditions for inference been met
Answer:
No. The data in this study were not based on a random method. This is a key requirement for an inference to be made from the two-sample t-test.
Step-by-step explanation:
1. Hayden can use the two-sample t-test (also known as the independent samples t-test)to find out if there was a difference in the time spent in the checkout time between two grocery stores and to conclude whether the difference in the average checkout time between the two stores is really significant or if the difference is due to a random chance. There are three conditions to be met when using the two-sample t-test.
2. The first condition is that the sampling method must be random. This requirement was not met in this study. Each customer from each store should have an equal chance of being selected for the study. This was not achieved.
3. The distributions of the sample data are approximately normal. This is achieved with a large sample size of 30 customers selected for each study.
4. The last but not the least condition is the independence of the sample data. Sample data here is independent for both samples.

Angel gave the store clerk $50 to buy 4 T-shirts. The store clerk gave her
$18.16 in change. Each T-shirt cost the same aount.
What is the cost in dollars and cents for each T-shirt?
Answer:
7.96
Step-by-step explanation:
50-18.16=31.84
31.84 divided by 4 = 7.96
Answer:
Each T - shirt costs $7.96
Step-by-step explanation:
4x + 18.16 = 50
subtract 18.16 from both sides.
4x = 31.84
divide both sides by 4
x = 7.96

Answer:
Step-by-step explanation:
1 Kg of carrot = 40 p
1 1/2 Kg of carrot = 40 * [tex]\frac{3}{2}[/tex] = 20 * 3 = 60 p = £ 0.60
1 kg of potato = 52 p
3 kg of potato = 52 *3 = 156 p = £1.56
1 box of tea bags = 90 p
Number of boxes for £1.80 = 1.80 ÷ 0.90 = 2 boxes
4 packs of yogurt = £4.80
1 pack of yogurt = 4.80 ÷ 4 = £1.20
Total = 0.60 + 1.56 + 1.80 +4.80 = £ 8.76

Step-by-step explanation:

Dependent event is,
D) a group of events whose later outcomes are affected by previous outcomes.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We know that;
The two events Event A and event B are said to be dependent if the occurrence of one outcome affects the occurrence of the other outcome.
Since, If we have a bag containing 5 blue marbles, 2 red marbles and 3 green marbles then if we draw first marble and then draw second without replacement.
Then, the event of drawing a blue marble first and then a green marble are dependent events.
Hence, Dependent event is,
a group of events whose later outcomes are affected by previous outcomes.

To shade this on a number line, we can find the point that corresponds to 0.375 and shade it.
What is a number line?It is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
We have,
To shade the number line to show 3/5 x 5/8, we can first convert the fractions to decimals:
So,
3/5 = 0.6
5/8 = 0.625
Next,
We can multiply these decimals together to find the product:
= 0.6 x 0.625
= 0.375
To shade this on a number line, we can find the point that corresponds to 0.375 and shade it.
If the number line extends from 0 to 1, with tick marks every 0.1, we can count over 3.75 tick marks from 0 and shade the point that corresponds to that location.
The shaded point should fall between 0.3 and 0.4 on the number line.
Thus,

Suppose you and a friend form a band. You want to record a demo. Sony Studios rents for $150 plus $20 an hour. Capitol Studios rents for $200 plus $15 an hour. Use a system of equations to help you to determine when the studios charge the same amount.
at what number of hours do the studios charge the same amount?
Answer:
200 < 225 + 80x < 550
The 200 is the amount the Jenna currently have.
225 + 80x is the amount that Jenna has to pay given x number of hours.
550 is the sum of Jenna's 200 and additional 350 she can get by selling pre-ordered Cds. This is the maximum amount she can pay for the studio rental and sound technicians.
Step-by-step explanation:
225 + 80x < 550
80x < 550 -225
80x < 325
80x / 80 < 325/80
x < 4.06 or 4 hours
225 + 80x → 225 + 80(4) = 225 + 320 = 545
The number of hours for the sound technician will range from 1 hour to 4 hours.
Assuming they will use 6 hours.
225 + 80(6) = 225 + 480 = 705
705 - 550 = 155
Jenna has to raise an additional $155 to pay off the studio rent and 6 hours of sound technicians.
this might be wrong but, i hope it helps
Answer:
Step-by-step explanation: times the hour by four on each and get 60 then it would be an equal pay for the hours.
