solve the equation

x² =64

The percentage of students who do not walk to class and do not have a lunchbox is 28.25 %.

From the illustration:

Total number of students = 400

Number of students that do not walk and do not have a lunchbox = 113

Percentage component = number of component/total number x 100

Thus:

Percentage of students who do not walk to class and do not have a lunchbox:

  = 113/400 x 100%

  = 28.25 %

To the nearest hundredth = 28.25%

In other words, the percentage of students who do not walk to class and do not have a lunchbox is 28.25%.

Step-by-step explanation:

Therefore, the height of the tower is approximately 121.4 meters.

The value of 3.52 × 2.5 is 8.8

Multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations.

For example if there are 10 groups and 5 mangoes are put in each group, the total number of mangoes in the region is calculated as;

10groups × 5 mangoes each

= 50mangoes

Similarly , solving 3.52 × 2.5

changing both of the term to whole number we multiply both term by 100.

Therefore , it will be 352 × 250. It will be easier to solve this way.

Therefore 352 × 250 = 88000

we can divide the answer by 10000 again

= 88000/10000 = 8.8

therefore 3.52 × 2.5 = 8.8

Answer:

Step-by-step explanation:

Okay, so this is impossible to tell the amount of spaces, but let's say it was 4000 for VIP and 4000 for Popular Stands. Multiply $30 by 4000, and you get $120k Earnings. To check your answer, Divide 120,000 by 4000, and you get $30 for each stand.

Now, let's move on with the VIP stands. A VIP Stand costs $50, so 4,000 x $50 = $200k earnings. To check your answer, divide 200,000 by 4000, and you get $50 for each VIP Stand.

If you need to find each variant, go by 1k seat increments, i.e. 1000 and 7000, 2000 and 6000, etc.

Answer:

y=1x-7

Step-by-step explanation:

The coordinates of the vertex of the parabola are (3, -7). The focus of the parabola is located at (3, -3). The equation of the directrix is y = -11.

The given equation of the parabola is in the form (x - h)^2 = 4p(y - k), where (h, k) represents the vertex and p represents the distance between the vertex and the focus/directrix.

Comparing the given equation with the standard form, we can see that the vertex is at (3, -7).

The coefficient 4p in this case is 16, so p = 4. Since the parabola opens upward, the focus will be p units above the vertex. Therefore, the focus is located at (3, -7 + 4) = (3, -3).

To find the directrix, we need to consider the distance p below the vertex. Since the parabola opens upward, the directrix will be p units below the vertex. Hence, the equation of the directrix is y = -7 - 4 = -11.

In summary, the coordinates of the vertex are (3, -7), the focus is located at (3, -3), and the equation of the directrix is y = -11.

The right question is:

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied.

The YSORT method of sex selection, developed by the Genetics \& IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 30 couples use the YSORT method and give birth to 30 babies, the sex of the babies is recorded. Does the procedure represent a binomial distribution?

A. No, because there are more than two categories for each trial.

B. No, because the trials of the procedure are not independent.

C. No, because the probability of success differs from trial to trial.

D. Yes, because the procedure satisfies all the criteria for a binomial distribution.

Answer:

5+7=12-35=-23

Step-by-step explanation:

The conversion is given as 1, 760 feet per second

We need to convert 20miles per hour to feet per second

First, we should convert miles to feet

1 mile = 5280 feet

Then,

20 miles = x

Cross multiply

20 × 5280 = x

x = 105, 600

Per hour = I hour = 60 seconds

To find the conversion, we divided the conversion to feet by that of the time

= 105, 600/60

= 1, 760 feet per second

Thus, the conversion is given as 1, 760 feet per second

Answer:

Answer: C

Step-by-step explanation:

a. Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71

b.   the probability  that the mean value of the 40 houses is less than $500,000 is 0.9863

a. The mean of the distribution is given as $403,000 and the standard deviation is $278,000.

To estimate the probability that a randomly selected house  has a value less than $500,000:

P( x < 500,000)=P(x=0)+P(x=500)

=0.34+0.37+

=0.71

Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71

b. -since 40 is larger than or equal to 30, we assume a normal distribution.

-The probability can therefore be calculated as:

P(x')=P( z < (x' -u)/σ.sqrt(n)))

P(z< (500-403)/(578sqrt(40)))

=P(z<2.2068)

=0.986336

Hence, the probability  that the mean value of the 40 houses is less than $500,000 is 0.9863

Answer:

(a) The average rate of change from 0 to 2 is 6

(b) The average rate of change from 3 to 5 is 24

(c) The average rate of change from -3 to 0 is -9

Step-by-step explanation:

The formula for the average rate of change (AROC) is given by:

\(AROC=\frac{f(b)-f(a)}{b-a}\)

(a):

Finding the AROC from 0 to 2

To find the average rate of change from 0 to 2, we use f(2) and f(0), while we plug in 2 for b and 0 for a:

\(\frac{f(2)-f(0)}{(2-0)}\\ \\\frac{((3(2)^2+4)-(3(0)^2+4))}{(2-0)} \\\\\frac{(16-4)}{(2)}\\ \\\frac{12}{2}\\ \\6\)

Thus, the average rate of change from 0 to 2 is 6.

(b):

Finding the AROC from 3 to 5:

To find the average rate of change from 3 to 5, we use f(5) and f(3), while we plug in 5 for b and 3 for a:

\(\frac{f(5)-f(3)}{(5-3)}\\ \\\frac{((3(5)^2+4)-(3(3)^2+4))}{(2-0)} \\\\\frac{(79-31)}{(2)}\\ \\\frac{48}{2}\\ \\24\)

Thus, the average rate of change from 5 to 3 is 24.

(c):

To find the average rate of change from -3 to 0, we use f(0) and f(-3), while we plug in 0 for b and -3 for a:

\(\frac{f(0)-f(-3)}{(0-(-3))}\\ \\\frac{((3(0)^2+4)-(3(-3)^2+4))}{(0+3)} \\\\\frac{(4-31)}{(3)}\\ \\\frac{-27}{3}\\ \\-9\)

Thus, the average rate of change from -3 to 0 is -9.

An absolute value is the numerical value of a number without consideration of its sign. It can be represented graphically by a straight line known as a number line. Absolute value equations are equations that include absolute values of variables or unknown quantities. The following are examples of how to write an absolute value equation in the form |x-c|=d to fit the provided solution sets:

Example 1:

Solution set: {x|x≤-3 or x≥1}
Absolute value equation: |x-(-1)|=4
Explanation: -1 is the midpoint of the two ranges (-3 and 1) in the solution set. |x-(-1)|=|x+1| is the absolute value expression for the midpoint -1. The distance d from -1 to the solutions' furthest endpoints, 1 and -3, is four, hence the value of d in the absolute value equation is 4.

The tiles represent an algebraic equation. The first step in solving an equation like this is moving all constants to one side. The constants are the numbers with variables or x's.

Answer:

a) 13/25

b) 12/15

Step-by-step explanation:

a) Since it is with replacement, the chance of them being both the same colour will be

P(both red) + P(both black) = (6/15*6/15) + (9/15*9/15)

                                              = 13/25

b) If they are both different colours, then we will be working out

P(both colours) = (6/15*9/15)*2 = 12/25   (Its *2 because the other way of pulling both colours is 9/15*6/15 which is the same but flipped)

Another way of working this question out is

P(1-All red or all blue) which from above we know that All red or all blue is 13/25 so

P(1-All red or all blue) = 1 - 13/25 = 12/25
