Answer:
1.56×10^10 cL
Step-by-step explanation:
There are 1000 liters in a cubic meter, so 10^5 centiliters in a cubic meter. The 1.56×10^5 cubic meters will then have ...
(1.56×10^5 m^3)×(10^5 cL/m^3) = 1.56×10^10 cL
_____
That's 15,600,000,000 cL.

An angle measures 78.6° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
so required angles are 50.7°and 129.3°
Step-by-step explanation:
Let the angle be x
another angle = x + 78.6°
so,
x + x + 78.6° = 180° {being sum of supplementary angle}
so, 2x + 78.6° = 180°
or, 2x = 180° - 78.6°
or, x = 101.4/2
so, x = 50.7°
so another angle = x + 78.6°
= 50.7° + 78.6°
= 129.3°

Question: Describe how to eliminate the parameter to change from parametric to rectangular form. How does this ability help us with graphing parametric equations?
Answer:
rectangular equation, or an equation in rectangular form is an equation composed of variables like xx and yy which can be graphed on a regular Cartesian plane. For example y=4x+3y=4x+3 is a rectangular equation.
A curve in the plane is said to be parameterized if the set of coordinates on the curve, (x,y)(x,y) , are represented as functions of a variable tt .
x=f(t)y=g(t)x=f(t)y=g(t)
These equations may or may not be graphed on Cartesian plane.

The scores for a particular examination are normally distributed with a mean of 68.5% and a standard deviation of 8.2%. What is the probability that a student who wrote the examination had a mark between 80% and 100%? Give your answer to the nearest hundredth.
Answer:
[tex]P(80/100<x<100/100)=0.08[/tex]
Step-by-step explanation:
We are given that
Mean,[tex]\mu=68.5[/tex]%=68.5/100
Standard deviation, [tex]\sigma=8.2[/tex]%=8.2/100
We have to find the probability that a student who wrote the examination had a mark between 80% and 100%.
[tex]P(80/100<x<100/100)=P(\frac{80/100-68.5/100}{8.2/100}<\frac{x-\mu}{\sigma}<\frac{100/100-68.5/100}{8.2/100})[/tex]
[tex]P(80/100<x<100/100)=P(1.40<Z<3.84)[/tex]
We know that
[tex]P(a<Z<b)=P(Z<b)-P(Z<a)[/tex]
Using the formula
[tex]P(80/100<x<100/100)=P(Z<3.84)-P(Z<1.40)[/tex]
[tex]P(80/100<x<100/100)=0.99994-0.91924[/tex]

3x-2=2(x-5)
find the value of x
Now we have to,
find the required value of x.
Let's begin,
→ 3x-2 = 2(x-5)
→ 3x-2 = 2x-10
→ 3x-2x = -10+2
→ x = -8
Hence, value of x is -8.
Answer:
x = -8
Step-by-step explanation:
3x - 2 = 2 ( x + 5
Solve for x.
Let's solve,
3x - 2 = 2 ( x + 5 )
Step 1:- Distribute 2.
3x - 2 = 2 × x + 2 × 5
3x - 2 = 2x - 10
Step 2 :- Move constant to the right-hand and change their sign.
3x = 2x - 10 + 2
Step 3:- Add -10 and 2.
3x = 2x - 8
Step 4 :- Move variable to the left-hand side and change their sign.
3x - 2x = -8
Step 5 :- Subtract 2x from 2x.
x = -8
Hence, value of x = -8.

Find dy/dx given that y = 1 - cos x / sin x
Answer:
tan x
Step-by-step explanation:
The given function y is a quotient, so we must apply the quotient rule first. Recall that (d/dx)cos x = -sin x and that (d/dx)sin x = cos x.
Then the derivative of the given quotient is:
(sin x)[0 - (-sin x)] [sin x]^2
dy/dx = --------------------------- = ----------------- = 1

When male workers were asked how many hours they worked in the previous week, the mean was with a standard deviation of . Does this suggest that the population mean work week for men exceeds hours
Answer:
We can conclude that the population mean work week for men exceed 40 hours.
Step-by-step explanation:
Given that :
Mean, xbar = 45.6
Standard deviation, s = 14.6
Sample size, n = 893
x = 40
Hypothesis :
H0 : μ = 40
H1 : μ > 40
Using test statistic for one sample t test :
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (45.6 - 40) ÷ (14.6/√(893))
T = (5.6 / 0.4885703)
Test statistic = 11.46
Using the Pvalue approach :
Reject H0 : if Pvalue < α
Pvalue for test statistic of 11.46 will be approximately 0 (Extremely low)
Hence, Pvalue < α ; We reject H0 ; and conclude that population mean work week for men exceed 40 hours

The brand B must be eliminated since it has highest percentage 4.79%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here,
Brand A percentage = 40/913 ×100
= 4.38%
Brand B percentage = 38/792 ×100
= 4.79%
Brand C percentage = 21/626 ×100
= 3.35%
Brand D percentage = 15/451 ×100
= 3.32%
Therefore, brand B must be eliminated since it has highest percentage 4.79%.

An object is dropped from 24 feet below the tip of the pinnacle atop a 1468-ft tall building. The height h of the object after t seconds is given by the equatior h= - 16t2 + 1444. Find how many seconds pass before the object reaches the ground. seconds pass before the object reaches the ground. (Type an integer or a decimal.)
Answer:
9.5 seconds pass before the object reaches the ground.
Step-by-step explanation:
Height of the ball:
The height of the ball after t seconds is given by the following equation:
[tex]h(t) = -16t^2 + 1444[/tex]
Find how many seconds pass before the object reaches the ground.
This is t for which h(t) = 0. So
[tex]h(t) = -16t^2 + 1444[/tex]
[tex]-16t^2 + 1444 = 0[/tex]
[tex]16t^2 = 1444[/tex]
[tex]t^2 = \frac{1444}{16}[/tex]
[tex]t^2 = 90.25[/tex]
[tex]t = \pm \sqrt{90.25}[/tex]
Since it is time, we only take the positive value.
[tex]t = 9.5[/tex]
9.5 seconds pass before the object reaches the ground.
