A rectangular water tank has the following dimension:
Length = 3 feet, Width = 2 feet, Height = 2.5 feet. Find the amount of water it can hold in cubic centimeter.
Answer:
424,752.7 cm³
Step-by-step explanation:
Since you need to convert from English units to Metric units, you can do that first.
Convert each measurement to centimeters instead of feet since your final answer is in cubic centimeters.
1 foot = 30.48 centimeters
Length = 3 ft 30.48cm
----- x ------------ = 91.44 cm
1 1 ft
Width = 2 ft 30.48cm
------- x ------------- = 60.96 cm
1 1 ft
Height = 2.5 ft 30.48cm
-------- x ------------ = 76.2 cm
1 1 ft
The volume is equal to L x W x H
91.44cm x 60.96cm x 76.2cm = 424,752.7 cubic centimeters
Martha Stewart has developed a new perfume. She decides to test its side effects by spraying the perfume in 31 randomly chosen houses. She records the level of antigens that create an allergic response. If the antigen level is high enough, the person will go into anaphylactic shock. The mean of her sample is a lot bigger than the median, but Martha hopes that a 90% confidence interval will contain zero. Her confidence interval is (0.116, 1.884). Disappointed, she offers you $144 to find an acceptable, realistic way to change the confidence interval to contain zero. What could you say to earn the money
The acceptable and realistic ways to to change the confidence interval to contain zero are;
Martha should decrease x-bar by providing medicine to treat shock to the perfume users.Decrease sample size than 30Increase the confidence level, till the interval contains zeroReasons:
The confidence interval is given by the following formula;
[tex]CI=\bar{x}\pm t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex]
When the mean, [tex]\overline x[/tex], is positive and large, both values, [tex]\bar{x}+ t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], and [tex]\bar{x} -t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], will be positive.
Therefore, Martha has to either intervene to reduce the mean also known as x-bar
Increasing the confidence level will increase the allowable error such that [tex]\bar{x} < t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}}[/tex], and the interval will contain zero
Therefore;
Martha should decrease x-bar, [tex]\overline x[/tex], by providing medicine to treat shock to the perfume usersUse a much smaller sample size, n, such that [tex]t_{\alpha/2} \cdot \dfrac{s}{\sqrt{n}} > \bar{x}[/tex]Increase the confidence level to 95% or 99%, thereby increasing the error boundLearn more here:

Answer:
x = 3/5
Step-by-step explanation:
5th root of Y is notated in exponential notation as Y^(1/5), which is Y to the one fifth (1/5) power.
So, the 5th root of 19^3 is (19^3)^(1/5) = 19^(3 * 1/5) = 19^(3/5), since (A^a)^b = A^(a*b).

v = u + at
Make u the subject of the formula.
Plz, Write down the answer and don’t put spaces.
Answer:
u=v-at
Step-by-step explanation:
When making something the subject of the formula, we need to get that thing on 1 side of the equation all by itself. To do this, we need to rearrange.
Because I can see that the side with my "u" has a "+at", I need to get the "+at" onto the other side of the "=", I can do this by subtracting it on both sides (because that - is the inverse of +). So I now have v-at=u. Which is the final answer.
Note: it doesn't matter which side U is on, as long as it is alone (so this equation can also be written as u=v-at.
mrs. jenningswants to take her kids on a field trip to the musem. the bus cost a total 100 and the meusem will charge 2 per student. what is the maximum number od students that mrs. jennings cantake to the meusem without exceeding her budget of 150
On a budget of $150, Mrs. Jennings will only be able to take 25 kids to the museum.
Mrs. Jennings has $150 in total and has to spend it on the bus and getting the kids into the museum.
After she spends on the bus, she will be left with:
= Budget - Cost of bus
= 150 - 100
= $50
She then spends $2 per kid. The total number of kids she can bring into the museum is:
= Amount remaining/ Cost per kid
= 50 / 2
= 25 kids
In conclusion, she can only take 25 kids.

When we Evaluate. [tex]0 / -1 * 0^2 * -4[/tex] the values is 0. To evaluate the expression, follow the order of operations (PEMDAS/BODMAS):
P - Parentheses/Brackets
E - Exponents/Orders
MD - Multiplication and Division (from left to right)
AS - Addition and Subtraction (from left to right)
The expression is: [tex]0 / -1 * 0^2 * -4[/tex]
Step 1: Exponents/Orders
0^2 = 0 (Any number raised to the power of 0 is always 0).
Step 2: Division
0 / -1 = 0 (Any number divided by 0 is undefined, but in this case, it would be 0).
Step 3: Multiplication : 0 * 0 * -4 = 0

 what is the geometric sequence and the 8th term and the 10th term
Answer:
The geometric sequence is decreasing by 0.5 * each term
common ratio = 0.5
an equation for this exact sequence would be
50(0.5)^x-1
Step-by-step explanation:
To find the common ratio for a geometric sequence we can divide the previous term value by the next term value
so 50 / 25 = 0.5
and to check we can divide
25 / 12.5 = 0.5
So our common ratio is 0.5
Step-by-step explanation:
Given sequence:
50, 25, 12.5, ...The first term is 50 and the common ratio is:
r = 12.5/25 = 25/50 = 1/2The equation:
