Fill in the blank with the appropriate word or expression. For B>0, the graph of y = sin Bx will have a period of _____
Answers
For B>0, the graph of y = sin Bx will have a period of (2π/B) units. The period of a sine function is the length of one complete cycle of the function.
The period of a trigonometric function is the length of one complete cycle of the function.
For the sine function, this is the distance between two consecutive points at which the sine value is equal to zero, or the distance between two consecutive maxima or minima. In this case, the graph of y = sin Bx is multiplied by a factor of B, which will stretch or compress the graph along the x-axis by a factor of B.
Therefore, the period of the graph will be (2π/B) units.

Line m represents a translation of line L3 units down and 2 units left. Which equation represents line L?
Answers
The linear equation L, which is a translation of line M, can be written as:
y = (2/3)*x - 2
So the correct option is the last one.
How to find the equation of line L?
First, we need to find the equation of line M.
Remember that the general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
On the graph we can see that the y-intercept is y = -2, then we wll get:
y = a*x - 2
And we can also see that the line passes through (-3, -4)
Replacing these values we will get:
-4 = a*-3 - 2
-4 + 2 = -3a
-2/-3 = a
2/3 = a
So line M is:
y = (2/3)*x - 2
And line M is a translation of 3 units down and 2 units left of L, then L is a translation of 3 units up and 2 units to the right, then we can write line L as:
y = (2/3)*(x - 2) - 2 + 3
y = (2/3)*x + (2/3)*-2 - 2 + 3
y = (2/3)*x - 4/3 + 1
y = (2/3)*x - 1/3
So the correct option is the last one.

in calculating which means differ, each pair of means needs a unique range. t/f
Answers
It is true that in calculating which means differ, each pair of means needs a unique range.
To determine if two means are different, a statistical test such as a t-test or an ANOVA is typically used. These tests compare the means of two or more groups and require a unique range for each group. This range is typically represented by the variance or standard deviation of the group's data.
For example, if we have two groups of data, group A and group B, and we want to determine if the mean of group A is different from the mean of group B, we would need the range of data for group A and the range of data for group B. The range of data includes the variance or standard deviation which is used to calculate the t-value or the F-value which is used to determine if the means are significantly different. Without this information, we cannot accurately compare the means and determine if they are different.

Answer:
8
Step-by-step explanation:
First look at the left, under the weight 2 there are 2 little boxes one of them is 1. so the other one must be one. that'll make this small group 2+1+1 =4, which means the other side to balance it, it is also 4.
now we've got 2*4 = 8 under 13. so left side total = 13+8 = 21
now look at the right side, it also must be 21. we already know there is a 5, then under neath the 5, to balance the remaining weight 21-5 = 16, each side must be equal. so each side = 8.
watermelon itself is one side, so it's 8.

Since RQ is congruent to PS and RS is congruent to QP, QT = SU, therefore QT and SU are congruent which means PT and RU are also congruent
What is a parallelogram?A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. The Sum of all the interior angles equals 360 degrees.
One the property of a parallelogram is that the opposite lines are parallel and congruent.
Therefore RQ = PS ( they are both congruent)
PS = RS ( they are both congruent )

After rewriting the given equation, we have the resultant equations as (B) -2.3p - 10.1 = 6.49p - 4 and (C) -230p - 1010 = 650p - 400 - p.
What are equations?Two expressions joined by an equal sign form a mathematical statement known as an equation.
An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.
So, we have the equation:
2.3p - 10.1 = 6.5p - 4 - 0.01p
Now, we can rewrite them as follows:
-2.3p - 10.1 = 6.49p - 4
-230p - 1010 = 650p - 400 - p
Therefore, after rewriting the given equation, we have the resultant equations as (B) -2.3p - 10.1 = 6.49p - 4 and (C) -230p - 1010 = 650p - 400 - p.

Answer:

2. Decay
3. Decay
Step-by-step explanation:
Growth means as x increases, y increases too. On the other hand, decay means as x increases, y decreases. There's the theory for exponential function regarding this growth and decay.
Growth
If the base is not a decimal or a fraction then it's growth.
Decay
If the base is a decimal or a fraction then it's decay.
From the problem, first function has base of 5. Hence, it's growth. On the other hand, second and third function both have decimal and fraction as the base. Hence, it's decay.
When considering growth or decay graph, we can ignore the coefficient since it doesn't determine the growth and decay. The only thing that determines if a function increases or decreases is the base under the exponent.

Find the mean of the three numbers at the right 2 1/3 3 2/3 5 1/4

Answer:
To find the mean (average) of a set of numbers, we add them together and divide by the number of items in the set.
The first step is to convert all the fractions into a common denominator. In this case, the least common multiple of 3, 3, and 4 is 12.
2 1/3 = 7/3
3 2/3 = 11/3
5 1/4 = 21/4
Now we can add these numbers together:
7/3 + 11/3 + 21/4 = (7 + 11 + 21) / 3 = 39/3 = 13
There are three numbers, so we divide by 3.

A. P-value
B. power of the test
C. Type Il error
D. significance level
Answers
Option D is the correct answer. The probability that a test correctly rejects a false null hypothesis is called the significance level.
The significance level, also known as alpha or α, is a measure of the strength of the evidence that must be present in your sample before you will reject the null hypothesis and conclude that the effect is statistically significant.
The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta). The quantity (1 - β) is called power, the significance level is the probability of rejecting the null hypothesis when it is true.
For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. Lower significance levels indicate that you require stronger evidence before you will reject the null hypothesis.

A loan of $25,000 has an annual simple interest rate of 5.5%. The total cost of the loan is $38,750.
B. How long does it take to repay the loan?
Answers
===========================================
Work Shown:
A = final value = 38750
P = amount loaned = 25000
i = interest
i = A - P = 38750 - 25000 = 13750
Now apply the simple interest formula to solve for t.
i = P*r*t
13750 = 25000*0.055*t
13750 = 1375*t
t = 13750/1375
t = 10 years to pay off the loan
