Answer:
13 1/8 -9 6/7 = 3 15/56
Step-by-step explanation:
13 1/8 -9 6/7 = ?
convert to a common denominator:
56 works in this case
13 7/56 - 9 48/56 = ?
it's complicated to subtract 48/56 from 7/56 so let's convert 13 7/56 to 12 63/56
12 63/56 - 9 48/56 = 3 15/56
Use a calculator to solve the equation.

Answer:
x = 0.4
Step-by-step explanation:
Answer:
x=0.4
Step-by-step explanation:
Given function:
-9.5x+0.81=-2.99find xCombine first value by 0.81:
-9.5+0.81=-2.99-19x/2+0.81=-2.99Subtract 0.81 both from sides:
-19x/2+0.81-0.81=-2.99-0.81Simplifly -19x/2:
-19x/2=-3.8Multiply all terms by similar term:
2·19x/2=2·3.8Divide both terms by -7.6:
-19x/-19-7.6/19=0.4Therefore, x=0.4.

Answer:
13.9 mm
Step-by-step explanation:
To find the diagonal of the box, x, apply the following formula, d = √(l² + w² + h²)
Where,
d = x
l = 12 mm
w = 5 mm
h = 5 mm
Plug in the values
x = √(12² + 5² + 5²)
x = √194
x = 13.9 mm (nearest tenth)
What are the solutions of the quadratic equation (x + 3)2 = 49? A. O x = 2 and x = - 10 B.O.x = 4 and x = -10 C.O x=-2 and x = -16 D.O x = 40 and x = -58
Answer:
B. x = 4 and x = -10
Step-by-step explanation:
First, expand the equation
(x + 3)² = 49
(x + 3)(x + 3) = 49
x² + 6x + 9 = 49
Subtract 49 from both sides
x² + 6x -40 = 0
Factor
(x + 10)(x - 4) = 0
Solve
x + 10 = 0
x = -10
x - 4 = 0
x = 4
So, the correct answer is B. x = 4 and x = -10

A two-sample tt-test for a difference in means will be conducted to investigate whether the average amount of money spent per customer at Department Store M is different from that at Department Store V. From a random sample of 35 customers at Store M, the average amount spent was $300 with standard deviation $40. From a random sample of 40 customers at Store V, the average amount spent was $290 with standard deviation $35. Assuming a nuk hypothesis of no difference in population means, which of the following is the test statistic for the appropriate test to investigate whether there is a difference in population means Department Store M minus Department Store V?
A. t= √300-290 /35^2/40 + 40^2/35
B. t = 300-290 / √40^2 +35^2 / 35+40
C. t= 300-290 / √40+35 / 35+40
D. t= 300-290 / √40^2 /35 +35^2/ 40
E. t= 300-290 /√40 /35+ 35/40
a. A
b. B
c. C
d. D
e. E
Answer: D
Step-by-step explanation:
The test statistic is t = 1.14.
What is Central Limit Theorem?The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
here, we have,
Before testing the hypothesis, we need to understand the central limit theorem and subtraction of normal variables.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
From a random sample of 35 customers at Store M, the average amount spent was $300 with standard deviation $40.
This means that , μ_m = 6.761
From a random sample of 40 customers at Store V, the average amount spent was $290 with standard deviation $35.
This means that , μ_v = 5.534
Assuming a null hypothesis of no difference in population means
At the null hypothesis, we test that there is no difference, that is, the subtraction of the means is 0. So
H₀ = 0
At the alternate hypothesis, we test if there is difference, that is, the subtraction of the means is different of 0. So
H₁ ≠ 0
The test statistic is:
t = X - μ / s
In which X is the sample mean, is the value tested at the null hypothesis, and s is the standard error.
0 is tested at the null hypothesis:
This means that μ= 0
From the samples:
X = 10
s = 8.737
The test statistic is t = 1.14.

Answer: A reflection of C (8,-4) would be (8,4).
Step-by-step explanation:
This is because it is crossing as the same over the x-axis. The reflection of C would be the same, just over the x axis, meaning the -4 would become 4. If it were over the y-axis, it would be (-8,-4). Hope this helps.
Find the amplitude of the solution
y=-4sin1/3x
Answer:
c. 4
Step-by-step explanation:
The amplitude of a graph is basically the distance from the top of the wavelength to the bottom of the wave length. When dealing with the equation itself the amplitude is represented by the initial number being multiplied to the sin cos or tan. Since the amplitude is just the distance and direction does not matter, this value is always positive. Therefore, in this scenario, the amplitude would be 4.
From the figure, your friend concludes that m<BAD > m<BCD. How would you correct your friend's mistake?
Answer:
BC > AD
Step-by-step explanation:
The opposite side to BC is greater, therefore making m<BCD > m<BAD. Since the legs are congruent, this is the only difference that need-be mentioned.
As the opposite angle of a larger side of a triangle is larger hence
m∠BAD > ∠mBCD.
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
From the figure itself, ΔABD and ΔBCD share a common side BD.
Given, Side AB is congruent to side CD and Side AD is greater than side BC.
We know opposite angle of a larger side of the triangle is larger.
Therefore, m∠BAD > ∠mBCD.

Find the slope of the line from the table below
Answer:
m = -10
Step-by-step explanation:
m = y2 - y1 / x2 - x1
m = 60-50 / -2 - -1
m = 10/ -1
m = -10
Answer:
-10
Step-by-step explanation:
We can use two points from the table to find our slope.
Remember, the slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. We can use the points (-1,50) and (-2,60). Let's substitute the values into the formula.
[tex]\frac{60-50}{-2-(-1)}[/tex]. This gets us to [tex]\frac{10}{-1}[/tex], so our slope is -10.
