Because it’s statistical

Step-by-step explanation:

Answer:

C. How many board games require a deck of card to play?

Step-by-step explanation:

A. is automatically out because you will only get one answer and you need to have veniality.

B. is also automatically out because then again you will only get one answer.

D. is a tricky one thought, it may look like it is the right answer but it is not because you will once again only get one answer. And based on how the question was worded it sounds like they were asking a specific person. (You have to ask more than one person in order to make that question statistical.)

For example, Say the question was: How many times have you watched star wars this past month? It may not be the same question but it has the same format. So, if you ask someone how many times have they had watched Star Wars this past month, they will say a specific number, like 7. The same goes with question D.

Answer:

Y-intercept:3

slope: -6

Step-by-step explanation:

because the slope ends with x because that's what will go on the x line of a graph.and the y-intercept ends with y because that's how the number will increase.Hope it helps:)!

The equation -6x + 3y = -9 is rearranged to y = 2x - 3. The slope (m) is 2, and the y-intercept (b) is -3.

To find the slope and y-intercept of the line represented by the equation -6x + 3y = -9, we need to rearrange it into the slope-intercept form (y = mx + b), where m is the slope, and b is the y-intercept.

Step 1: Rearrange the equation:

-6x + 3y = -9

Add 6x to both sides:

3y = 6x - 9

Step 2: Solve for y:

Divide both sides by 3 to isolate y:

y = (6/3)x - (9/3)

y = 2x - 3

Now, the equation is in the slope-intercept form. The slope (m) is the coefficient of x, which is 2, and the y-intercept (b) is the constant term, which is -3.

Answer: A:12

Step-by-step explanation:

10*x=10x

15*8=120

120/10x=12

The value of x for the given problem is 12.

A straight line segment joining two points on a circle is called a chord. It is, in fact, a segment of a line whose ends lie on the circle. Drawing a line segment between the two ends and passing through the center of the circle is a common method of symbolizing a chord.

The products of the measures of the chord segments are equal when two chords cross over one another.

The following is the product to get the length x:

10 * x = 8 * 15

10x = 120

x = 120/10

x = 12

Therefore, the value of x is 12

slope: 2

x-intercept = -1/2

Step-by-step explanation:

The equation is in  y = mx + b  form.  m = slope.  The slop is equal to 2.

To find the x-intercept set y equal to 0 and solve for x.

0 = 2x + 1

-1 = 2x

x = -1/2

Answer:

slope= 2

x intercept=-0.5 or -1/2

Step-by-step explanation:

y= mx+b

m is the slope, therefore 2 is the slope of the equation.

X-intercept

substitute 0 to y

0=2x + 1

Subtract 1 from both sides

0-1=2x+1-1

-1=2x

Divide both sides by 2

-1/2=2x/2

x=-1/2 or -0.5

Answer: Helen paid $250 for the bike

Carla paid $250 for the bike.

They both paid the same amount

Step-by-step explanation:

Final answer:

By calculating the pre-tax prices of the bicycles using the provided sales tax amounts and rates, we determine that both Helen and Carla's bicycles cost $250 before tax, meaning neither paid more for their bicycle excluding the sales tax.

Explanation:

To determine who paid more for their bicycle excluding the sales tax, we need to calculate the pre-tax price of each bicycle using the sales tax amounts given. This requires us to work backwards from the sales tax paid to the original cost of the item.

For Helen, we know that the sales tax was $14, and the rate was 5.6%. We find the pre-tax price by dividing the sales tax paid by the sales tax rate (converted into decimal form):

Pre-tax price for Helen = $14 / 0.056 = $250

For Carla, the sales tax was $12, and the rate was 4.8%. The pre-tax price calculation is similar:

Pre-tax price for Carla = $12 / 0.048 = $250

Since both pre-tax prices are equal, neither Helen nor Carla paid more for their bicycle when we do not include the sales tax.

Answer: A.) Critical values: r= ± 0.514, no significant linear correlation

Step-by-step explanation:

r = 0.105

n = 15

The level of significance for a two-tailed test is 0.05

The degrees of freedom = n - 2 = 15 - 2 = 13

Using the pearson product moment correlation Coefficient table ; The critical value for the correlation Coefficient is ±0.513977

When the correlation coefficient (for a sample of 15 drawn from the same population) is less than ±0.514 (critical value), that means no significant linear correlation exists.

Answer:

0.0853

Step-by-step explanation:

Step 1

The first step would be to find the Z score

Formula for Z score is given as

z = x – μ /( σ ÷ √n)

Where

x = observed value

μ = mean

σ = Standard deviation

n = sample size

In the question we were given the above values as :

x = observed value = $7500

μ = mean = $7200

σ = Standard deviation = $1200

n = samples size = 30

Z score (z) = $7500 – $7200 /($1200÷ √30)

Z score = $300/ ( $1200 ÷ √30)

Z score = 1.3693063938

Approximately, the Z score = 1.37

Step 2

Using this formula:

1 - P(z > 1.37)

Using the Standard distribution table,

P(z > 1.37) is given as

0.9146565

Therefore,

1 - P(z > 1.37)

= 1 - 0.9146565

= 0.0853435

In the question we were asked to round it up to 4 decimal places

= 0.0853

Therefore, the probability that the mean daily revenue for the next 30 days will exceed​ $7000 is 0.0853.

Answer:

The price of a citron is 8 and the price of a wood apple is 9

Step-by-step explanation:

First of all we make two equations that represents the problem

c = citrons price

w = wood apples price

8c + 9w = 145

9c + 8w = 144

we clear c in the first equation

8c + 9f = 145

8c= 145 - 9w

c = (145 - 9w) /8

c = 145/8 - 9w/8

we replace c by (145/8 - 9w/8) in the second equation and solve

9(145/8 - 9w/8) + 8w = 144

163.125 - 10.125w + 8w = 144

163.125 - 144 = 10.125w - 8w

19.125 = 2.125w

19.125/2.125 = w

9 = f

now we replace w in the first equation

8c + 9w = 145

8c + 9(9) = 145

8c + 81 = 145

8c = 145 - 81

8c = 64

c = 64 / 8

c = 8

The price of a citron is 8 and the price of a wood apple is 9

Answer: 57.50

Step-by-step explanation:

50*.15=7.50

50+7.5=57.50

B - $57.50

Step-by-step explanation:

To find the cost of the available bicycle before taxes, we need to add another 15% to the original $50. To do that, all you do is multiply $50 by 15%, and then re-add the $50. Work is shown below:

First, change 15% into a decimal:

15% -> 15/100 -> 0.15

Next, lets find the cost of the available bicycle:

x = 50 (0.15)

x = 7.5

Now add the $50 back 7.5:

50 + 7.5 = 75.50

So your answer is B = $57.50 

Answer: 1.43 hours

The time taken by Tory will be= 50/x hours to dock

Emilio pilots for another 2 hours and this will be= (50/x)+2) hours

Emilio pilots 120 km for (50/x)+2) hours

d/t=r

120/(50/x) +2) =x

120 = [x(50/x) +2)]

120= 50+2x

2x= 120-50

2x = 70

x= 70/2

x = 35

Tory takes 50/35 = 1.43 hours for 50 km.

Answer:

x = 3

Step-by-step explanation:

The solution to the equation is x = (-1 + √(57))/2.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the logarithmic identity log(a) + log(b) = log(ab), we can simplify the left side of the equation:

log(x - 1) + log(x + 2) = log((x - 1)(x + 2))

So the equation becomes:

log((x - 1)(x + 2)) = log 12

Using the logarithmic identity log(a) = b is equivalent to a = 10^b, we can rewrite the equation as:

(x - 1)(x + 2) = 12

Expanding the left side and simplifying, we get:

x² + x - 14 = 0

Using the quadratic formula, we find:

x = (-1 ± √(1 + 4 x 14))/2

x = (-1 ± √(57))/2

Since we can't take the logarithm of a negative number, we discard the negative solution and obtain:

x = (-1 + √(57))/2

Therefore,

The solution to the equation is x = (-1 + √(57))/2.

Step-by-step explanation:

Here we have the standard equation of an hyperbola given as follows;

[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1[/tex]

Where:

a = x intercept

The asymptote is ±(b/a)x

Since the intercept, a is ± 4, the vertices are (-4, 0) and (4, 0)

We are given the asymptote as y = 3/4x, therefore, since the genral form of the asymptote is ±(b/a)x, comparing, we have;

±(b/a)x ≡ 3/4x

We have a = ±4, therefore, b = 3

Hence the equation of the hyperbola is found by putting in the values of a and b in the general form as follows;

[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1 \Rightarrow \frac{x^2}{4^2} - \frac{y^2}{3^2} =1[/tex]
