Answer: 17 friends

Step-by-step explanation:

Let the number of people that will go to the game be represented by x.

Based on the information given, we can form an equation which will be:

15x + 2.25x + 1.75x = 350

19x = 350

x = 350/19

x = 18.4

That means 18 people can go to the games. Since Xavier is going, he will invite 17 friends more.

Answer:

[tex](x - 5)^2 + (y - (-3))^2 = 16[/tex]

Answer:

(x - 5)² + (y + 3)² = 16

Step-by-step explanation:

(x - h)² + (y - k)² = r²

(h, k) is the center = (5, -3)

r is the radius = 4

r² = 4² = 16

Answer:

8) 10 15/16 ft³

9) 20 5/6 ft³

Step-by-step explanation:

Volume of a rectangular prism is

l * b * h,

Question 8

We're given the area

Area = l * b

So we substitute the area for length and breadth.

Volume = Area * height

Volume = 4 3/8 * 2 1/2

Volume = 35/8 * 5/2

Volume = 175/16

Volume = 10 15/16 ft³

Question 9

Volume = 5 * 1 2/3 * 2 1/2

Volume = 5 * 5/3 * 5/2

Volume = 5 * 25/6

Volume = 125/6

Volume = 20 5/6 ft³

Answer:

-1.5 L/h

Step-by-step explanation:

The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.

We need to find the average rate of decrease in volume of water. It can be solved as follows :

[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]

The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

The normalcdf means the normal cumulative density function, it can be accessed from the TI Calculators from the DIST section which also includes the normalcdf, invNorm, tpdf and other distribution functions.

The syntax is as follows :

normalcdf (lower bound, upper bound, mean, standard deviation)

Hence, to Obtian the probability that a value is between a and b, with mean, x and standard deviation, s

The normalcdf is written as normalcdf(a, b, x, s)

Answer:

19° = m∠B

73° = m∠T

88° = m∠R

Step-by-step explanation:

Let x = measure of angle B

then 4x - 3 = measure of angle T

 and 31 + 3x = measure of angle R

x + 4x - 3 + 31 + 3x = 180

8x + 28 = 180

8x = 152

x = 19° = m∠B

4(19) - 3 = 73° = m∠T

31 + 3(19) = 88° = m∠R

Answer:

80.5π cm

Step-by-step explanation:

We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.

Answer:

y-9=4/5(x+7)

Step-by-step explanation:

Point slope for is y-y1=m(x-x1). In this case, y1 is 9, x1 is -7, and m is 4/5. Therefore, we can fill in this equation. The equation will be y-9=4/5(x--7) This is equal to y-9=4/5(x+7).

0 +5 _ = 5 is it: identity property.[if 0 is added or subtracted]

2 + (6 + 8) =(2 + 6)+ _8 associated property

[if added or multiplied]

Answer:

Slope = 2/7

y-intercept = 0

Proportional = yes

It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

From what we can see, the slope of the given line is 2/7

As we can see, there is no y-intercept; so the y-intercept value is 0

As we can see, we can multiply each x value by 2/7 to get the corresponding y-value

What this mean is that both variables are proportional

Answer:

1 < x < 12

Step-by-step explanation:

The triangles satisfy the Converse Hi nge Theorem Condition the two triangles have two corresponding equal sides. Thus, the included angle of the triangle that has the largest length of the third side is greater than the included angle of the other triangle with a lesser third side length.

Thus,

33 > 3x - 3

Solve for x

33 + 3 > 3x - 3 + 3

36 > 3x

36/3 > 3x/3

12 > x

To ensure the angle is not 0 or negative, thus:

3x - 3 > 0

Solve for x

3x - 3 + 3 > 0 + 3

3x > 3

3x/3 > 3/3

x > 1

Possible range of values of x would be:

1 < x < 12

Answer:

The 4 packe is better value.

Answer:

The 4 pack has better value.

Step-by-step explanation:

To find the toilet roll price, divide by the number of rolls.

2.04 ÷ 4 = 0.51

4.68 ÷ 9 = 0.52

0.52 > 0.51

So, the 4 pack has better value.

Have a wonderful day! :)

The experimental and theoretical probabilities for the given experiment are:

i) The experimental probability of rolling a 2 is equal to the quotient between the number of times that the outcome was a 2 and the total number of times that the number cube was rolled, so the probability is:

P = 8/50 = 0.16

ii) The theoretical probability assumes that all the numbers (6) have the same probability of rolling up.

Then all the numbers have a probability of 1/6.

This means that the theoretical probability of rolling a 2 is:

P(2) = 1/6 = 0.167

iii) The experimental probability of NOT rolling a 2 is computed in a similar way than the first one, if out of 50 rolls, in 8 we rolled a 2, then in 42 we did not rolled a 2.

So the probability is:

P = 42/50 = 0.84

iv) The theoretical probability of not rolling a 2 is equal to 1 minus the theoretical probability of rolling a 2.

P = 1 - 1/6 = 5/6 = 0.833...

v) For the experimental probability of getting a 1, we see that out of 50 rolls, in 10 we rolled a 1, so the probability is:

P = 10/50 = 1/5 = 0.2
