Graph B

Step-by-step explanation:

Linear functions are straight lines.

Linear functions are straight lines. Graph B has a straight line which means it is a linear function.

A function is defined as a relation between the set of inputs having exactly one output each.

Linear functions are straight lines.

In the given option Graph A has the curve graph which can't be a linear function.

Graph B has a straight line which means it is a linear function.

Graph C the lines are not straight so it can't be a linear function.

Similarly, in Graph D, it can't be a linear function.

Answer:

25 meters

Step-by-step explanation:

in this case they give us the information about the lake and that length corresponds to the perimeter.

the perimeter of a circle has the following formula:

p = 2 * pi * r

then r equals:

r = p / pi * 2

replacing we have:

r = 157 / (2 * 3.14)

r = 25

which means that the radius of the lake is 25 meters

Find the perimeter of the circle is the same as finding the circumference of the circle.

Circumference Formula: C = 2πr

Divide the diameter by 2 to find the radius.

7 / 2 = 3.5

Solve using the given values.

C = 2(3.14)(3.5)

C = 2(10.99)

C = 21.98

Therefore, the circumference (perimeter) of the circle is 21.98cm²

A traffic Study from last year claimed that the average commute time in the San Francisco Bay Area is 45 min. The urban planner will see if there is evidence the average commute time is greater than 45 minutes

Answer:

13.31 and - 3.31

Step-by-step explanation:

(x + y)^2 = x^2 + y^2 + 2xy ; x + y = 10; x^2 + y^2 = 56

This means ;

10^2 = 56 + xy;

100-56 = XY

44 = xy---------(3)

From x + y = 10

x = 10- y

Substitute that in eqn 3;

We have: 44 = (10-y) y

44 =10y - y^2

Y^2-10y -44 = 0;

From formula method of quadratic equation;

Y =[ - (-10) +_ √ (-10)^2 + 4 × 1 x (-44)] / 2 × 1

y = [ 10 +_√ (100 + 176) ]/ 2]

y = [ 10 +_ √ 276]/ 2

y = [ 10 + √ 276]/ 2 or [ 10 _ √ 276]/ 2

y = 13.31 or - 3.31

Similarly x = 10 - 13.31 or 10 - (-3.31)

x = - 3.31 or 13.31

The required ordered pairs are (5+√3, 5-√3) and  (5-√3, 5+√3).

Given equations are:

[tex]x+y=10[/tex]......(1)

[tex]x^{2} +y^{2} =56[/tex].......(2)

An equation is a statement that equates to two statements.

On squaring equation (1) we get

[tex]x^{2} +y^{2} +2xy=100[/tex]

From equation(2) [tex]x^{2} +y^{2} =56[/tex]

So, [tex]2xy=44[/tex]

[tex]xy=22[/tex]

[tex]y=\frac{22}{x}[/tex]

Put [tex]y=\frac{22}{x}[/tex] in equation (1)

We get [tex]x+\frac{22}{x} =10[/tex]

[tex]x^{2} -10x+22=0[/tex]

[tex]x=5+\sqrt{3}[/tex]

[tex]x=5-\sqrt{3}[/tex]

If  [tex]x=5+\sqrt{3}[/tex],

[tex]y=10-x[/tex]

[tex]y=5-\sqrt{3}[/tex]

So the ordered pair is [tex](5+\sqrt{3}, 5-\sqrt{3} )[/tex]

If  [tex]x=5-\sqrt{3}[/tex],

[tex]y=10-x[/tex]

[tex]y=5+\sqrt{3}[/tex]

So the ordered pair is [tex](5-\sqrt{3}, 5+\sqrt{3} )[/tex]

Hence, the required ordered pairs are [tex](5+\sqrt{3}, 5-\sqrt{3} )[/tex] and [tex](5-\sqrt{3}, 5+\sqrt{3} )[/tex].

Answer:

48

Step-by-step explanation:

In similar polygons, every side of one polygon is a certain number of times bigger than the corresponding side of the other polygon. This number is the scale factor. Since the perimeter of each polygon is the sum of the lengths of the sides of that polygon, the perimeters also have the same scale factor that the sides do.

For example, if a triangle has 3 sides measuring 5 cm each and a similar triangle has 3 sides measuring 10 cm each, you see that each side of the second triangle is 2 times the length of the corresponding side of the first triangle. The scale factor from the smaller triangle to the larger triangle is 2. Now look at the perimeters. Since 5 + 5 + 5 = 15 and 10 + 10 + 10 = 30, the perimeters are 15 cm and 30 cm, and again, the perimeter of the second triangle is the same 2 times bigger than the perimeter of the first triangle.

Now look at your problem.

The perimeter of the smaller flag to the right is 16.

We see a side on the larger flag is 15, but we don't see the same side length on the smaller flag, so 15 does not help us.

Now we see that a side of the smaller flag measures 4 and the corresponding side of the larger flag measures 12. We divide the larger side length by the corresponding smaller side length to find the scale factor.

12/4 = 3

The scale factor from the smaller flag to the larger flag is 3. The perimeters also have the same scale factor of 3.

perimeter = 3 * 16 = 48

Answer: 48

Answer:

48

Step-by-step explanation:

Similar polygons have their sides in proportion, and we call the proportion between pairs of corresponding sides on two similar polygons the scale factor between them. We want to find the perimeter of the larger flag given the smaller one, and comparing the side with length 12 on the larger one with the side of length 4 on the smaller, we get a scale factor of 12 / 4 = 3.

This tells us that all the lengths on the larger flag are 3 times longer than the corresponding lengths on the smaller flag. What happens to the perimeter when we scale all of the lengths? Well, if every side gets multiplied by three, the sum of those sides will naturally be multiplied by 3, too.

Our large flag has a perimeter 3 times bigger than the smaller one, then, and 3 × 16 = 48.

Answer:

Length of hypotenuse = √( a² + b²)

Step-by-step explanation:

The question is incomplete and unclear. From the question, it is clear we are to determine the hypotenuse of the triangle. Hence the triangle is a right angled triangle.

Find attached the diagram used in solving the question.

From the diagram,

a = opposite

b = adjacent

c = hypotenuse

To find the hypotenuse of a right angled triangle, we apply Pythagoras theorem.

Using Pythagoras theorem

Hypotenuse² = opposite ² + adjacent²

Insert the values of each, we have:

c² = a² + b²

Then we find the Square root both sides

c = √( a² + b²)

So we can insert the values of a and b if we are given.

For instance, if b = 6

c = √( a² + 6²)

Using the diagram,

Hypotenuse: c = √( a² + b²)

Answer:

There is not enough evidence to support the claim that the liquid diet yields a higher mean weight loss than the powder diet (P-value = 0.15).

Step-by-step explanation:

This is a hypothesis test for the difference between populations means.

The claim is that the liquid diet yields a higher mean weight loss than the powder diet.

Then, the null and alternative hypothesis are:

[tex]H_0: \mu_1-\mu_2=0\\\\H_a:\mu_1-\mu_2< 0[/tex]

The significance level is 0.05.

The sample 1 (powder diet group), of size n1=49 has a mean of 42 and a standard deviation of 12.

The sample 2 (liquid diet group), of size n2=36 has a mean of 45 and a standard deviation of 14.

The difference between sample means is Md=-3.

[tex]M_d=M_1-M_2=42-45=-3[/tex]

The estimated standard error of the difference between means is computed using the formula:

[tex]s_{M_d}=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma_2^2}{n_2}}=\sqrt{\dfrac{12^2}{49}+\dfrac{14^2}{36}}\\\\\\s_{M_d}=\sqrt{2.939+5.444}=\sqrt{8.383}=2.895[/tex]

Then, we can calculate the t-statistic as:

[tex]t=\dfrac{M_d-(\mu_1-\mu_2)}{s_{M_d}}=\dfrac{-3-0}{2.895}=\dfrac{-3}{2.895}=-1.04[/tex]

The degrees of freedom for this test are:

[tex]df=n_1+n_2-1=49+36-2=83[/tex]

This test is a left-tailed test, with 83 degrees of freedom and t=-1.04, so the P-value for this test is calculated as (using a t-table):

[tex]\text{P-value}=P(t<-1.04)=0.15[/tex]

As the P-value (0.15) is greater than the significance level (0.05), the effect is not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that the liquid diet yields a higher mean weight loss than the powder diet.
