Tom simplified an expression in three steps, as shown:
x to the power of negative 2 multiplied by y to the power of 4, over y multiplied by x to the power of 4 multiplied by x to the power of 4 multiplied by y to the power of negative 2, the whole to the power of 4
Step 1:
x to the power of 2 multiplied by y to the power of 8, over y to the power of 4 multiplied by x to the power of 8 multiplied by x to the power of 8 multiplied by y to the power of 2
Step 2:
x to the power of 2 multiplied by y to the power of 8, over y to the power of 6 multiplied by x to the power of 16.
Step 3:
x to the power of negative 13 multiplied by y squared

Find the mean for the scores: 3.850; 5,300: 8,540; 4.300; 5,360.
Answer:5470
Step-by-step explanation:The mean is the average of the data collected in the graph.Step one add everthing together which is 3,850+ 5,300+ 8,540+ 4,300+5,360=27,350, Step two divide 27,350 with the total amount of numbers that's in the graph which is 5 if you divide those two number together you will get on average 5,470.
Use the table to find the value of the following.
Sin117°
Answer:
[tex]\sin 117^{\circ} \approx 0.8910[/tex]
Step-by-step explanation:
Sine reaches upper bound when [tex]\theta = 90^{\circ}[/tex] and then decreases until reaches lower bound when [tex]\theta = 180^{\circ}[/tex]. By symmetry, we find the following fact:
[tex]\sin 117^{\circ} = \sin (90^{\circ}+27^{\circ}) = \sin (90^{\circ}-27^{\circ})[/tex]
[tex]\sin 117^{\circ} = \sin 63^{\circ}[/tex]
By information form table we find that:
[tex]\sin 63^{\circ} \approx 0.8910[/tex]
Therefore, we conclude that value of the given angle is:
[tex]\sin 117^{\circ} \approx 0.8910[/tex]
Kyle fills the candle mold with liquid candle wax. If
the candle has a volume of 99 cubic inches, what is the
width of the mold?
Answer:
w = 3 inches
Step-by-step explanation:
Given that,
The volume of the candle, V = 99 cubic inches
Length, l = 11 inches
Breadth, b = 3 inches
We need to find the width of the candle. The candle is in the form of a cuboid. The volume of cuboidal shape is given by :
[tex]V=lwh[/tex]
Put all the values,
[tex]w=\dfrac{V}{lb}\\\\w=\dfrac{99}{11\times 3}\\\\w=3\ inches[/tex]
So, the width of the mold is 3 inches.
the measures of a triangle are in the ratio 2:3:5. what are the measures of the angles?
(give all 3 angle measurements pls)
9514 1404 393
Answer:
36°, 54°, 90°
Step-by-step explanation:
We have to assume that the given measures are angle ratios, not side ratios. Sides in the ratios 2:3:5 will not form a triangle.
For some multiplier x, the angle values will total 180°.
2x +3x +5x = 180
x = 180/(2+3+5) = 18
Then the angle measures are ...
2x° = 2·18° = 36°
3x° = 3·18° = 54°
5x° = 5·18° = 90°
The angle measures are 36°, 54°, and 90°.

The ideal output of a particular oil-rig in the Mexican Gulf is at least 2000 barrels per day. If the output is lesser than that, the foreman raises an red flag at the end of the day. Old Joe the Retired Statistician watches from the shore every day. After 28 days, the red flag was raised on 16 of those days. Could Joe conclude that the oil-rig is operating at a non-ideal condition most of the time
Answer:
Mexican Gulf Output of a Oil-Rig
Based on 57% red flag days, Joe, the retired statistician, who watches from the shore for the red flag every day, cannot conclude that the oil-rig is operating at a non-ideal condition most of the time, but more of the time.
Step-by-step explanation:
Ideal output of a particular oil-rig, at least = 2,000 barrels per day
When output is lesser than 2,000, a red flag is raised by the foreman
Number of days counted = 28
Number of days when red flag was raised = 16
Proportion of days when the red flag was raised = 16/28
= 0.57
or 57%

Find the value of x in the triangle below
Answer:
50
Step-by-step explanation:
a triangle's angles add up to 180 degrees.
100-80=100
since two of the sides are the same length, the two angles must also be the same so you just divide 100 by two
100/2=50

Find the simple interest on the following amounts:
a K4000 invested at 6% p.a. for 4 years
b K23 000 invested at 6.5% p.a. for 8 years
K580 borrowed at 5% p.a. for 9 months
inte
с
500
Answer:
a. Simple interest = K960
b. Simple interest = K11,960
c. Simple interest = K261
Step-by-step explanation:
Given the following data;
a. Principal = K4000
Interest rate = 6%
Time = 4 years
To find the simple interest;
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest.
P is the principal.
R is the interest rate.
T is the time.
Substituting into the equation, we have;
[tex] S.I = \frac {4000*6*4}{100} [/tex]
[tex] S.I = \frac {4000*6*4}{100} [/tex]
[tex] S.I = \frac {96000}{100} [/tex]
S.I = K960
b. Principal = K23 000
Interest rate = 6.5%
Time = 8 years
To find the simple interest;
[tex] S.I = \frac {PRT}{100} [/tex]
Substituting into the formula, we have;
[tex] S.I = \frac {23000*6.5*8}{100} [/tex]
[tex] S.I = \frac {1196000}{100} [/tex]
S.I = K11,960
c. Principal = K580
Interest rate = 5%
Time = 9 months
To find the simple interest;
[tex] S.I = \frac {580*5*9}{100} [/tex]
[tex] S.I = \frac {26100}{100} [/tex]
S.I = K261
A local brewery distributes beer in bottles labeled 24 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 23.7 ounces and sample standard deviation of 0.8 ounces. . Test the claim by the government agency that the population mean is less than 24 ounces at the 0.01 level of significance.
Answer:
We reject H₀ . We support the feeling of people from a government agency
Step-by-step explanation:
Population information:
Population mean μ = 24 ou
Sample information:
Sample size n = 50 then degree of fredom df = n - 1 = 49
Sample mean x = 23,7
Sample standard deviation s = 0,8
Hypothesis Test:
Null Hypothesis H₀ x = μ
Alternative hypothesis Hₐ x < μ
Significance level α = 0,01
We can conclude from the alternative hypothesis that we should develop a one tail-test ( to the left " if a local brewery is cheating its customers that mean, they are selling less beer than they are supposed to)
With α = 0,01 and df = 49 we get from t-student table t(c) = - 2,4
To calculate t(s)
t(s) = ( x - μ ) / s/√n
t(s) = ( 23,7 - 24 ) / 0,8/√50
t(s) = - 0,3* 7,07 / 0,8
t(s) = - 2,12 / 0,8
t(s) = - 2,65
Comparing t(c) and t(s)
|t(c)| < |t(s)|
2,4 < 2,65
Then t(s) is in the rejection region we reject H₀ , and agree with a government agency in the fact that at 99 % of confidence interval shows that local brewery is cheating customers

Step-by-step explanation:
\sqrt{-x+26}=x-6 −x+26=x−6
Answer:
x = 1 and 10
Step-by-step explanation:
Given the equation \sqrt{-x+26}=x-6, we are to find the value of x
Take the square of both sides
(\sqrt{-x+26})²= (x-6)²
-x+26 = (x-6)²
Expand the parenthesis
-x+26 = x²-12x+36
x²-12x+36+x-26 = 0
x²-11x+10 = 0
x²-10x-x +10 = 0
x(x-10) -1()-10) = 0
(x-1)(x-10) = 0
x - 1 =0 and x - 10 = 0
x = 1 and 10
Hence the value of x is 1 and 10

Answer:
Linear, the linear term is -21x and the constant term is -20. Last option is the answer
Step-by-step explanation:
We are given the following function:
[tex]y = (x - 5)(5x + 4) - 5x^2[/tex]
First we have to simplify y, before solving the question:
[tex]y = (x - 5)(5x + 4) - 5x[/tex]
Applying the distributive property:
[tex]y = 5x^2 + 4x - 25x - 20 - 5x^2[/tex]
[tex]y = 0x^2 - 21x - 20[/tex]
[tex]y = -21x - 20[/tex]
No quadratic term, so it is linear.
The linear term is -21x and the constant term is -20.
