Which is the graph of f(x) =3 sqrtx/4?

Answers:

===========================================

Explanations:

Part (a)

There is only one disc labeled "3" out of 10 total. So we end up with the probability 1/10.

---------------------

Part (b)

The list of numbers less than 4 are {1,2,3} which are 3 items out of 10 discs. We end up with 3/10.

---------------------

Part (c)

A square number, aka a perfect square, smaller than 10 is the list {1,4,9}

Since 1 = 1^2, 4 = 2^2 and 9 = 3^2

Like part (b), we end up with the same result of 3/10.

---------------------

Part (d)

The list of primes smaller than 10 is {2, 3, 5, 7}. Notice that 1 is not prime.

So we end up with 4/10 = 2/5.

Answer:

D

Step-by-step explanation:

Answer:0

Step-by-step explanation:

because 3x+1 is 0

The 3x+1 Conjecture asserts that, starting from any positive integer n, repeated iteration of this function eventually produces the value 1.

Answer:

Yes the samples can be drawn from a population with the same mean and standard deviation 10 hours

Step-by-step explanation:

We are given;

Sample mean for male employees; x1¯ = 63

Sample mean for female employees; x2¯ = 66

Sample size = 50

Standard deviation; σ = 10

First,let's define the hypotheses of the question;

Null hypothesis; H0: μ1 = μ2

Alternative hypothesis; Ha: μ1 ≠ μ2

Now, let's find the test statistic from the formula;

z = (x1¯ - x2¯)/(σ√(2/n))

Thus;

z = (63 - 66)/(10√(2/50))

z = -3/2 = - 1.5

Now, we are not given the significance value but usually when it is not given, we can adopt α = 0.05.

Thus, from online p-value from z-score calculator using; z = -1.5; α = 0.05; two tailed test; we have;

p-value = 0.13364

The p-value is greater than the significance value and thus we will fial to reject the null hypothesis and conclude that these samples can be drawn from a population with the same mean and standard deviation

Answer:

y = 1/3x -1

Step-by-step explanation:

The slope is  y2 - y1 / x2 - x1

y2 is 1

y1 is -1

x2 is 6

x1 is 0

So it is 1 - (-1) / 6 - 0, or 2/6, or 1/3

The slope is 1/3.

The y-intercept is the place where x is 0. It shows the y-intercept here as

(0, -1),  The y-intercept is  -1

Slope form is y = mx + b. m is the slope, 1/3, and b is the y-intercept, -1

So the equation is: y = 1/3x -1

Answer:

17.

Step-by-step explanation:

The differences form an arithmetic sequence 3, 5, 7, 9,,11.

The missing number  is 10 + 7 = 17.

This is a quadratic sequence.

The nth term = n^2 + 1.

Thus the 4th term = 4^2 + 1 = 17.

Answer:

option D

Step-by-step explanation:

Take the two through which the lines passes.

Let it be ( -5 , 0) and ( 0 , -3)

Step 1 : Find slope, m

     [tex]Slope,m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

                  [tex]= \frac{-3-0}{0--5} = \frac{-3}{5}[/tex]

Step 2 : Find the equation

      [tex](y - y_ 1) = m( x - x_1)\\\\( y - 0) = \frac{-3}{5} (x --5) \\\\y = -\frac{3}{5}( x + 5 ) \\\\y = -\frac{3}{5}x - 3[/tex]

The correct answer is A. Figure A.

A mathematical statement is a declarative sentence that expresses a truth or falsehood using mathematical symbols. It is usually made up of two terms that are related by an operator, such as an equals sign. Mathematical statements can be used to prove results, solve equations, and make predictions about the behavior of systems.

This diagram represents the statement "If it is a tree, then it has leaves" because the top box is labeled "tree" and the bottom box is labeled "has leaves". The arrow running between them indicates that if the condition of the top box is true, then the bottom box is also true. This is an example of a conditional statement.

You always get a unit rate from dividing. You always have two ways to do it, and get two unit rates, but one of them is more helpful.

Answer:

35 degrees

Step-by-step explanation:

180-55-55=70

180-70=110

180-110=70

70/2=35

Property: All straight lines from the centre of a circle are the same length, hence the triangles are isoceles.

======================================================

Explanation:

Inscribed angle ABC = 55 subtends the minor arc AC which is 110 degrees (use the inscribed angle theorem).

The inscribed angle BDC subtends the minor arc CB, which we'll call x for now.

The two minor arcs (AC and CB) combine to form the arc ACB. Note how this is a semicircle since AB is a diameter. For any semicircle, the arc measure is 180 degrees.

So,

(arc AC) + (arc CB) = arc ACB

110 + x = 180

x = 180-110

x = 70

This cuts in half to 35 which is the inscribed angle BDC, again we're using the inscribed angle theorem here.

Answer:

10 degrees C

Step-by-step explanation:

the difference between both temperatures is expressed by a subtraction

7 - -3 = 7 + 3 = 10

you could also do the subtraction the other way around :

-3 - 7 = -10

but the negative sign has no meaning for a distance between two points (a distance itself has no direction).

so, we are always using the absolute value of such difference calculations (when it is about lengths, distances, and so on, where the direction had no meaning).

and so, also the -10 is actually simply 10 for our problem here.

the temperature fell by 10 degrees.

Answer:

Cost for 50 songs: $64

Cost for s songs: s + 14

Step-by-step explanation:

Since it is $1 per song, if he downloaded 50 songs, it would be $50 extra dollars.

Add this to the monthly charge of 14:

50 + 14

= 64

So, the cost of 50 songs would be $64.

Now, find the cost for downloading s songs.

Each song is $1, so the cost can be represented by s + 14.

The answer is:

Cost for 50 songs: $64

Cost for s songs: s + 14

Answer:

A. The null hypothesis is [tex]H_0: \mu = 130[/tex].

The alternative hypothesis is [tex]H_a: \mu > 130[/tex]

B. The value of the test statistic is [tex]t = 1[/tex]

C. The p-value is of 0.1636.

D. The critical value is [tex]t_c = 1.711[/tex]

Step-by-step explanation:

Question a:

Customers at Costco spend an average of $130 per trip (The Wall Street Journal, October 6, 2010). One of Costco's rivals would like to determine whether its customers spend more per trip.

At the null hypothesis, we test if the mean is the same as Costco's, that is:

[tex]H_0: \mu = 130[/tex]

At the alternative hypothesis, we test if the mean is more than 130, that is:

[tex]H_a: \mu > 130[/tex]

B. Calculate the value of the test statistic.

The test statistic is:

We have the standard deviation for the sample, so the t-distribution is used to solve this question.

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

130 is tested at the null hypothesis:

This means that [tex]\mu = 130[/tex]

A survey of the receipts of 25 customers found that the sample mean was $135.25. Assume that the population standard deviation is $10.50 and that spending follows a normal distribution.

This means that [tex]n = 25, X = 135.25, s = 10.50[/tex]

Then

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{135.25 - 130}{\frac{10.50}{\sqrt{25}}}[/tex]

[tex]t = 1[/tex]

The value of the test statistic is [tex]t = 1[/tex]

C. Calculate the p-value.

Test if the mean is more than a value, so a right-tailed test.

Sample of 25, so 25 - 1 = 24 degrees of freedom.

Test statistic of t = 1.

Using a t-distribution calculator, the p-value is of 0.1636.

D. Calculate the critical value

24 df, using the standard 0.05 significance level.

Using a critical value calculator, the critical value is [tex]t_c = 1.711[/tex]
