solve for θ. sinθ = cos(θ+10)
a. 6°
b.66°
c.84°
d.40°
Answer: d. 40°
Step-by-step explanation:
Use the Cofunction Identity: sin Ф = cos (90° - Ф)
sin Ф = cos (Ф + 10) = cos (90° - Ф)
⇒ Ф + 10 = 90 - Ф
2Ф + 10 = 90
2Ф = 80
Ф = 40

Answer: 45 1/2
Step-by-step explanation:
Volume = 3 1/2 x 4 x 3 1/4
= 91/2
= 45 1/2 or 45.5
Answer:
45. 1/2 cubic inches
Step-by-step explanation:
Since volume of a cube = length x width x height, or V=Bh, we need to multiply 3 1/2, 4, and 3 1/4 together. 3.5 (3 1/2) x 4 = 14. 14 x 3.25 (3 1/4) is 45.5. This is also 45 1/2 in fraction form.
A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular sample of 50 packages, the mean amount dispensed is 8.171 ounces, with a sample standard deviation of 0.052 ounce.1. Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.01level of significance.)2.

The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001 ounce below 8.17if the null hypothesis is false.B. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001 ounce away from8.17 if the null hypothesis is true.A. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001ounce aboveB. The p-value is the probability of not rejecting the null hypothesis when it is false.
Answer:
We conclude that the mean amount packaged is equal to 8.17 ounces.
Step-by-step explanation:
We are given that in a particular sample of 50 packages, the mean amount dispensed is 8.171 ounces, with a sample standard deviation of 0.052 ounces.
Let [tex]\mu[/tex] = population mean amount packaged.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 8.17 ounces {means that the mean amount packaged is equal to 8.17 ounces}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu\neq[/tex] 8.17 ounces {means that the mean amount packaged is different from 8.17 ounces}
The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;
T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar X[/tex] = sample mean amount dispensed = 8.171 ounces
s = sample standard deviation = 0.052 ounces
n = sample of packages = 50
So, the test statistics = [tex]\frac{8.171-8.17}{\frac{0.052}{\sqrt{50} } }[/tex] ~ [tex]t_4_9[/tex]
= 0.1359
The value of t-test statistics is 0.1359.
Also, the P-value of test-statistics is given by;
the meaning of the p-value is that the p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001 ounces away from8.17 if the null hypothesis is true.
P-value = P( [tex]t_4_9[/tex] > 0.136) = More than 40% {from the t-table}
Since the P-value of our test statistics is more than the level of significance of 0.01, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.
Therefore, we conclude that the mean amount packaged is equal to 8.17 ounces.

A swimming pool holds exactly 184 cubic yards of water. Assuming that the depth of the pool is the same everywhere, what is the depth in meters if the pool is exactly 30.0 feet long and 20.0 feet wide
Answer:
The depth of the swimming pool is 2.52 meters
Step-by-step explanation:
To solve this problem properly, the first thing we are to do is to ensure that we are working in the same units at all points in time during the solution.
First of all, we will convert the length and breadth of the pool from feet to yards.
1 foot = 0.3333 yards
30 feet = 10 yards
20 feet = 6.67 yards.
The next step is to find the depth of the swimming pool using the volume and the available dimensions.
From the dimensions given, we can tell that the swimming pool will have a cuboidal shape. This means that the volume will be = length X breadth X depth.
hence we have
184 = 10 X 6.67 X depth
depth = 2.76 yards.
The final step will be to convert the answer we obtained in yards to meters.
1 yard = 0.9144metres
2.76 yards = 2.52 meters
The depth of the swimming pool is 2.52 meters

If 7x + 4 = -19 + 5x, then 2x – 14 equals A) 23 B) -23 C) -3 D) 16 E) NOTA
Answer:
2x-14 = -37
Step-by-step explanation:
7x + 4 = -19 + 5x,
Subtract 5x from each side
7x-5x + 4 = -19 + 5x -5x
2x +4 = -19
Subtract 4 from each side
2x +4-4 = -19 -4
2x = -23
We want to find 2x -14
2x = -23
2x-14
-23-14
-37
Answer:
-37
Step-by-step explanation:
First, let's solve for x.
7x+4= -19+5x
Subtract 5x from both sides of the equation.
(7x-5x)+4= -19 (+5x-5x)
(7x-5x)+4=-19
2x+4=-19
Subtract 4 from both sides of the equation.
2x(+4-4)=(-19-4)
2x=(-19-4)
2x= -23
Divide both sides of the equation by 2.
2x/2= -23/2
x= -23/3
x= -11.5
Next, let's find what 2x-14 is equal to. Substitute -11.5 in for x.
2x-14
2(-11.5)-14
Multiply 2 and -11.5
-23-14
Subtract 14 from -23.
-37
2x-14 is equal to -37.
Find the indicated side of the
right triangle.
Answer:
?=9
Step-by-step explanation:
We have a special right triangle, the 45-45-90 triangle.
In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.
Since we know that the side length is 9, this means that:
[tex]x=9\\\text{Hypotenuse}=x\sqrt2\\\text{Hypotenuse}=9\sqrt2[/tex]
The ? is 9.

Answer:
9x^4 -x
Step-by-step explanation:
( -8x + 3x^4 ) - ( -7x - 6x^4 )
Distribute the minus sign
( -8x + 3x^4 ) +7x + 6x^4
Combine like terms
3x^4 + 6x^4 -8x +7x
9x^4 -x
Answer:
x + 9x^4
Step-by-step explanation:
There is some confusion here. You likely meant by "3x 4" the power term 3x^4 and by "6x 4" the power term 6x^4. " ^ " indicates exponentiation.
Step 1: Eliminate the parentheses. Simply drop them from the first term.
The first term becomes -8x + 3x^4 and the second term becomes 7x + 6x^4.
Now combine like terms:
-8x + 3x^4
+ 7x + 6x^4
------------------
x + 9x^4

9. Find the slope of a line parallel to 3x - y = 1.
Answer:
slope = 3
Step-by-step explanation:
The slope of a line parallel to the given equation share the same slope. Note the slope intercept formula:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
First, isolate the variable, y. Subtract 3x from both sides:
3x (-3x) - y = 1 (-3x)
-y = -3x + 1
Next, divide -1 from both sides:
(-y)/-1 = (-3x + 1)/-1
y = 3x - 1
You are solving for the slope of a line parallel to the given equation. Since you are solving for parallel, the slope would be shared.
3 would be the slope of the line.

16 p = 208 p = Pls help quick
Answer:
p=0
Step-by-step explanation:
When you isolate both variables, one side becomes 0.
Answer:
p = 0
Step-by-step explanation:
16p=208p
Subtract 208p from both sides.
16p−208p=0
Combine 16p and −208p to get −192p.
−192p=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −192 is not equal to 0, p must be equal to 0.
p=0

[tex] \therefore \: x(x + 7) = 98 \\ {x}^{2} + 7x - 98 = 0 \\ {x}^{2} + 14x - 7x - 98 = 0 \\ x(x + 14) - 7(x + 14) = 0 \\ (x + 14)(x - 7) = 0 \\ (x + 14) = 0 \: or \: (x - 7) = 0 \\ x = - 14 \: or \: x = 7 \\ \\ when \: x = - 14 \\ x + 7 = - 14 + 7 = - 7 \\ \\ when \: x = 7 \\ x + 7 = 7 + 7 = 14 \\ [/tex]
Hence the required integers are - 14, - 7 or 7, 14
