The minimum amount to the nearest dollar according to the line of best fit from the graph is $26 because as y = $26, x = 0.

The line of best fit is a line that runs across a scatter plot of data points and best reflects the connection between them.

Let's make an assumption from the image below that;

We know that x = 0 at the y-intercept;

Thus, the minimum amount to the nearest dollar according to the line of best fit from the graph is $26 because as y = $26, x = 0.

Answer:

14 hours and 42 minutes

Step-by-step explanation:

Using the binomial distribution, it is found that there is a 0.25 = 25% probability of getting exactly 3 tails.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability of getting 3 tails is P(X = 3), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]

0.25 = 25% probability of getting exactly 3 tails.

Answer: 20 L of 33% solution and 60 L of 5% solution should be mixed

Step-by-step explanation:

0.33x + 0.05(80-x) = 0.12*80

0.33x + 4-0.05x = 9.6

0.33x - 0.05x = 9.6-4

0.28x = 5.6

x = 5.6/0.28

x = 20 L of 33% solution should be used

80-20 = 60 L of 5% solution should be used

Proof:

0.33*20 + 0.05*60 = 0.12*80

6.6 + 3 = 9.6

9.6 = 9.6

Answer:

y = x/2

Step-by-step explanation:

y = -x has a negative slope so cross this one out.

y = 2x has a steeper slope that would be above the black line so cross this one out

y = 0.001x has a slope that acends very slowly so cross this one out.

y = x/2 is the best match.

Some terminology:

 ⇒what is the slope

    ⇒ is the steepness of the line

        ⇒calculated by dividing the rise over the run

           ⇒ rise is the change in the y-direction

               ⇒ run is the change in the x-direction

                  ⇒look at the diagram I attached

 ⇒ how to find the slope in a linear equation

     ⇒look to the coefficient of the 'x' variable

        ⇒ that is the slope

      Ex. For the line y = x, the slope is 1

⇒A line with a positive slope rises from left to right while a line with a    negative slope falls from left to right.

   Ex. y=x has a positive slope and thus is rising

We want to find the equation that could represent the blue line

   ⇒ let's look into each equation and see whether they work or not

First case: [tex]y = -x[/tex]

  ⇒The equation given has the line falling, when the graph in the    

  equation is rising

       ⇒ not the answer

Second case: [tex]y=2x[/tex]

   ⇒ the equation given has the line that has a bigger slope than the

  the equation shown, which has a smaller slope than y = x

       ⇒ not the answer

Third case: [tex]y=\frac{1}{2}x[/tex]

    ⇒ the equation given fits the requirement of having a rising slope that

    is smaller than y = x

        ⇒ is a possible answer

Fourth case: [tex]y = 0.001x[/tex]

     ⇒ the equation given has a slope that is almost horizontal when the

     line shown in the graph doesn't

          ⇒ not the answer

Thus after examing all the choices:

   ⇒ Answer: [tex]y=\frac{1}{2}x[/tex]

The value of x is 5. Thus, the correct statement is:

x = 5 is a true solution because log subscript 2 Baseline (16) = 4

Log₂ (x + 11) = 4

x + 11 = 2⁴

x + 11 = 16

Collect like terms

x = 16 – 11

x = 5

Log₂ (x + 11) = 4

x = 5

Log₂ (5 + 11) = 4

Log₂ 16 = 4

Find the value of Log₂ 16

Log₂ 16 = n

16 = 2ⁿ

2⁴ = 2ⁿ

n = 4

Thus,

Log₂ 16 = 4

Answer:

3π

Step-by-step explanation:

The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.

The radius is given ad 6. So the circumference is:

2*π*6=12π

Now, since the angle of the arc is 90°, this is 1/4 of the circle.

This means that the arc length of this section will be 1/4th of the total circumference which is:

12π/4=3π

Answer:

The answer should be somewhere around 13.4375

Step-by-step explanation:

Since the price is 10.75 and it wants you to add 25% or a quarter to it. You can divide 10.75 by 4, which is 2.6875 and add it. You will get 13.4375.

The commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 =  q × p

Proof usually is generalized, ie, it applies for all possible cases of the given condition, or a large set of cases. But vertification is a check for single special case.

For this case, we've to verify that p × q = q × p when p =5/28 and q=49/35

For p =5/28 and q=49/35 we get:

[tex]p \times q = \dfrac{5}{28} \times \dfrac{49}{35} = \dfrac{5 \times 49}{28 \times 35}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]

Also, we get:

[tex]p \times q =\dfrac{49}{35} \times \dfrac{5}{28} = \dfrac{49 \times 5}{35 \times 28}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]

Thus, we get: p × q = 0.25 =  q × p

Hence, verified.

Thus, the commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 =  q × p

Answer:

The number (81.59) will round to 82.

Step-by-step explanation:

First, let us understand what the question means by "whole numbers".

Whole numbers are such integers that are positive. (Except 0, which is a non-positive and non-negative integer).

Whole numbers: 0, 1, 2, 3, 4, 5, 6....

If the number before the decimal is smaller than 50, then the number will round down. If the number before the decimal is greater than or equal to 50, then the number will round up.

We can see that 81.59 is between two integers (81 and 82). Therefore, 81.59 can either round down to 81 or round up to 82.

Since the number after the decimal (81.59) is greater than 50, the number rounds up to 82. Therefore, the number (81.59) will round to 82.

C, 60 degrees

Step-by-step explanation:

Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30

90+30 = 120
180-120 = 60

180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.

Answer:

The measure of the third angle is 60°.

Step-by-step explanation:

We are given a right triangle that has a 90 degree and two other angles that are unknown.

Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.

180° - 90° -  30° = 60°.

Using the z-distribution, as we are working with a proportion, it is found that:

a) The population proportion is of 0.625.

b) The interval is (0.586, 0.664).

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The sample size and the population proportion are given, respectively, by:

[tex]n = 1040, \pi = \frac{650}{1040} = 0.625[/tex]

Hence, the bounds of the interval are given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 - 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.586[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 + 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.664[/tex]
