Answer: It would cost $16 dollars for 4hrs

Step-by-step explanation:

1. First find the value of the first two hours so $5.50+$5.50=$11

2. Then calculate how much for the last two hours, so $2.50+$2.50=$5

3. Combine the two $11+$5=$16 for 4hrs

Answer:

The answer is a composite number Step-by-step explanation: If you multiply 3x3, that is 9, which is composite. Even if you go forever trying to multiply a prime number by a prime number, it will always be composite.

Answer:

XQ = QY

Step-by-step explanation:

A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of (left figure). The perpendicular bisector of a line segment can be constructed using a compass by drawing circles centered at and with radius and connecting their two intersections.

Actually Welcome to the Concept of the Bisectors.

Bisectors divide lines into two equal parts, so

QX = QY

Answer:

(0.5, 1)

Step-by-step explanation:

The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

[tex](\frac{-1+2}{2},\frac{5-3}{2})=(\frac{1}{2} ,\frac{2}{2} )=(0.5,1)[/tex]

The answer is thus (0.5, 1).

Answer:

10

Step-by-step explanation:

Miguel will circle 10 counters because 5/8 * 16 = 10.

Answer:

A. 10 is the correct answer.

Step-by-step explanation:

The equation is 5/8 x 16.

Here, there are 16 counters. This is also known as 2 rounds of 8, which is the denominator in our fraction. Since 8 is 1/2 times 16, 5 x 2, or 10, is the correct answer.

Hope this helps! :)

Answer:

-1.973

Step-by-step explanation:

Given the data :

Age 36 39 48 53 58

Bone Density 358 351 330 325 314

Equation of regression line is in the form:

yˆ=b0+b1x

Where y = predicted variable ;

b0 = intercept ; b1 = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = -1.97316X + 427.94399

From the equation ;

The slope or gradient (b1) = - 1.97316

Hence, estimated slope to 3 decimal places is : - 1.973

Answer:

Step-by-step explanation:

The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. There are several ways to find the y-intercept of an equation, depending on the starting information you have.

How to find the Y-Intercept from the Slope and Point.

Write down the slope and point. The slope or "rise over run" is a single number that tells you how steep the line is. This type of problem also gives you the (x, y) coordinate of one point along the graph. Skip to the other methods below if you don't have both these pieces of information.

Answer:

105 degrees

Step-by-step explanation:

l and m are parralel and are strait lines 180 degrees

angle 6 is corresponding to angle 2 so angle 2 is also 75 degrees

180 minus 75 equals 105 degrees

Answer:

There will be 7 students on each bus.

Step-by-step explanation:

If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:

63/9 = X

7 = X

Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.

Answer and Step-by-step explanation:

A random variable is a variable having numerical values determined by the outcomes of the experiment. A random variable may have a finite number or an infinite sequence of values said to be discrete.

A random variable that describes the number of automobiles sold at a dealership would be discrete one day. Simultaneously, a random variable represents the weight of a person in a kilogram or pounds.

The probability distribution of discrete random variable x is each possible value of x and the probability that x takes amount in one trial of the experiment.

The probability distribution of the random variable contains the following properties:

1- Each probability must be between 0 and 1.

0 ≤ p(x) ≤ 1

2- The sum of all probabilities is equal to 1.

Ʃp(x) = 1

A continuous random variable may assume any value from data. The continuous random variable takes costs that vary within one or more intervals. And it has a cumulative distribution function (CDF) that is absolutely continuous.

The random variable has an infinite number of possible values, which have zero probability. The range of this type of discount can have a nonzero chance.

The probability distribution of the random variable is described by probability density, where the probability can be calculated by taking the area under the curve.

Answer:

Step-by-step explanation:

Our given equation is 5 (4 × 3 + 3 × 4)

Using The Order of Operations (AKA): PEMDAS, we need to solve this.

The "P" stands for parentheses. We do have them, so we need to solve the operations inside of them.

We don't have any parentheses inside.

The "E" stands for exponents. We don't have any, so we need to move on.

The "M" stands for multiplication. We have two multiplication symbols, so we need to solve them.

1.  5 (4 × 3 + 3 × 4)    

2.  5 (12 + 3 × 4)

3.  5 (12 + 12)

The "D" stands for division. We don't have any of them, so we need to move on.

The "A" stands for addition. We have one of them, so we need to solve.

4.  5 (12 + 12)

5.  5 × 24

Now that we only have the operation 5 × 24, we can go ahead and solve.

6.  5 × 24 = 120

So now we know that when using The Order of Operations to solve the equation: 5 (4 × 3 + 3 × 4) results in a 120.

Answer:

x = 24yrs and y = 27yrs

Step-by-step explanation:

Let the age of one of the teachers be x

Let the age of the other teacher be y

From the second sentence;

x + y = 51 ----------(1)

From the first sentence;

x/y = 8/9 ------------(2)

Making y the subject of formula in equation (1) as follows;

y = 51 -x -------------(3)

Substitute (3) into (2) as follows;

x/51- x = 8/9

Cross multiply as follows:

9*x = 8(51- x)

9x = 408 - 8x

Collecting like terms;

9x + 8x = 408

17x = 408

Divide both sides by 17;

x = 24 yrs

Substitute x = 24 into equation (3) as follows;

y = 51 - 24

y = 27 yrs

Answer:

8/73

0.10959

21 players

Step-by-step explanation:

Given that:

Number of teams = 25

Number of players per team = 73

Number of players chosen for drug testing = 8

A) What is the probability that Erik Red is chosen for random drug testing in a specified week of the foosball season?

Number chosen per team / number of players per team

8 / 73 = 0.10959

B) What is the probability that Erik Red is chosen for random drug testing at least 5 times in the first 9 weeks of the foosball season?

P( being chosen at least 5 times)

USing binomial. Distribution

P(X =x) = nCr * p^x * (1-p)^n-x

To save computation time, we can use the binomial distribution calculator :

P(x≥5):p(x = 5) + p(x = 6) + p(x =7) + p(x = 8) +. P(x = 9) = 0.00136

C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?

Number who are chosen atleast 4 times :

P(x ≥ 4) = p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x = 8) +. P(x =9) = 0.0115

P(x ≥ 4) * number of players per team * nunber of teams in league

0.0115 * 73 * 25 = 20.9875

= 21 players

D) Let Y be the number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season. What is the maximum possible value of Y, i.e., the largest k such that P(Y=k) > 0?

Answer:

16

Step-by-step explanation:

y=6(3)-2

y=18-2

y=16

Answer:

8 = 4 +$

Step-by-step explanation:

Like you said, we need to use substitution to solve for y.

[tex]x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10[/tex]

Now that we've solved for y, we can plug in the number we got into one of the original equations. (You can choose either equation, but I will use the first one.)

[tex]x + 10 = 11\\\\x = 1[/tex]

Now we have the solution of this system.
