Answer:

Answered below.

Step-by-step explanation:

1) A double - blind study is simply an experiment in which neither the participants nor the people who carry out the experiment know who is receiving any particular treatment. This method is usually used in order to prevent a biased view in research results.

2) True because randomized simply means that subjects were assigned to the group randomly.

3) Placebo - controlled trial simply means that there was a control group that received only a placebo treatment which is mainly designed not to have real effect.

f(x,y)→(x-3,-y-2)

Step-by-step explanation:

So basically the base form is f(x,y) that is why I added it there. Then the transformation reflects the shape over the x-axis which changes it from f(x,y)→(x,-y). If you take point A, for example, it is (0,1). When reflected, as the formula shows, it becomes (0,-1) and that is where the negative sign before the y comes from. Then we translate point A left 3 and down 2. That makes the point become (-3,-3) which is where A prime is. That also changes the formula to f(x,y)→(x-3,-y-2). This should work for the ENTIRE shape and ALL THE POINTS. -DooDOoHeaad

Answer:

1.14

Step-by-step explanation:

0.8+0.34

The solution of the given expression will be 1.14.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is 8 tenths + 34 hundredths. The solution of the expression is,

E =  8/10 + 34 / 100

Solve the expression by the mathematical operation.

E = 0.8 + 0.34

E = 1.14

Therefore, the solution of the given expression will be 1.14.

Clay and ott are correct but stacie is wrong.

An Arithmetic progression (AP) is a special type of progression in which the difference between two consecutive terms is always a constant. The terms of an arithmetic progression series is a a+d, a + 2d, a + 3d, a + 4d, a + 5d,…

Given here, the sequence as 2,4,6..... thus this is an arithmetic sequence with common difference 2 and therefore the subsequent terms are as follows : 2,4,6,8,18......

Step-by-step explanation:

Also there is no following

The ratio of 12gm and 45 kg in simplest form is 3750 : 1.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Are two weights in different measurement forms, To write them as a ratio we have to make their scale of measurement equal.

We know 1kg is equal to 1000 grams.

Therefore, 45 kg is equal to 45000 grams.

So, The ratio of 12gm and 45 kg is 45000 : 12.

22500 : 6.

11250 : 3.

3750 : 1.

Answer:

f^-1(x) = 3 - 5x, second option

Step-by-step explanation:

To determine the inverse simply interchange the variables and solve for y;

f(x) = 3 - x / 5 -> Interchange the variables

x = 3 - y/5 -> Multiply either side by 5

5x = 3 - y -> Subtract three from either side

- y = 5x - 3 -> Divide either side by - 1

y = - 5x + 3

Your solution is f^-1(x) = 3 - 5x

Recall the following property of exponents:

[tex]a^b\cdot a^c=a^{b+c}[/tex]

[tex]\implies 216^{-3k}\cdot 216^{-2k}=216^{-3k-2k}=216^{-5k}[/tex]

Now, notice that 6² = 36 and 6³ = 216, which means that

[tex]216^{-5k}=36^{2k-1} \iff (6^3)^{-5k}=(6^2)^{2k-1}[/tex]

Recall another property of (real) exponents:

[tex](a^b)^c=a^{bc}[/tex]

[tex]\implies(6^3)^{-5k}=6^{3(-5k)}=6^{-15k}\text{ and }(6^2)^{2k-1}=6^{2(2k-1)}=6^{4k-2}[/tex]

So we have

[tex]216^{-5k}=36^{2k-1} \iff 6^{-15k}=6^{4k-2}[/tex]

Since both sides are equal powers of 6, that must mean that the exponents must be equal, so

[tex]-15k=4k-2[/tex]

Solve for k :

[tex]-15k-4k=(4k-4k)-2[/tex]

[tex]-19k=-2[/tex]

[tex]k=\dfrac{-2}{-19}=\boxed{\dfrac2{19}}[/tex]

Answer:

Step-by-step explanation:

Answer:   The equation of the line in slope-intercept form will be

y = (7/4)x + b

Since the line passes through the point (8,-2), plug in the values of the point into the equation to find b.

-2 = (7/4)(8) + b

-2 = 14 + b

-16 = b

The equation of the line is

y = (7/4)x - 16

In standard form,

-(7/4)x + y = -16

Multiply both sides of equation by -4.

7x - 4y = -64

Answer:

False

Step-by-step explanation:

From the question we are told that

The coefficient for the training is [tex]r = 0.55[/tex]

The standard error is [tex]SE = 1.06[/tex]

The confidence level is 95%

Generally the level of significant is mathematically represented as

[tex]\alpha =( 100 -95)\%[/tex]

=> [tex]\alpha = 0.05 [/tex]

Generally the critical value of [tex]\alpha = 0.05 [/tex] obtained from the normal distribution table is [tex]Z_{0.05} = 1.645[/tex]

Generally the test statistics is mathematically represented as

[tex]t = \frac{r }{SE}[/tex]

=> [tex]t = \frac{0.55}{1.06}[/tex]

=> [tex]t = 0.5189 [/tex]

Generally given that the [tex]t < Z_{\alpha }[/tex]

Hence  there is no sufficient evidence to conclude that the program has a positive and statistically significant impact on wages at a 95% confidence level.

Answer:

f(-6) = 40

Step-by-step explanation:

Step 1: Define

f(x) = 5(2 - x)

f(-6) is x = -6

Step 2: Substitute and Evaluate

f(-6) = 5(2 - (-6))

f(-6) = 5(2 + 6)

f(-6) = 5(8)

f(-6) = 40
