Hope I helped you even though this is really old. I just need to answer 5 questions for points

Answer:

75 students

Step-by-step explanation:

From the table, we can calculate the total number of students surveyed by Michael:

Total student surveyed = 13 + 15 + 32 = 60 students

We can see that out of the 60 students, 15 students played exactly one sport. Hence:

Proportion of students playing exactly one sport = 15 / 60 = 0.25

Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:

Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students

Answer:

if it's area, then:

area = 26.41 ft²

Step-by-step explanation:

area = πr² = (3.14)(2.9²) = 26.41 ft²

THats all i could come up with nothin mor nun less

Same Sides

When the sides are the same then the triangles are congruent. because they all have exactly the same sides. because the two triangles do not have exactly the same sides.

Answer: Step-by-step explanation:

Answer: y= -3x

Step-by-step explanation:

Use the slope-intercept form to find the slope.

m = −3

To find an equation that is parallel to y = −3x + 2, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

(0,0)

m = −3

Using the point-slope form

y − y1 = m (x − x1), plug in

m = −3, x1 = 0, and y1 = 0.

y − (0) = (−3) (x−(0))

Solve for y

y = −3x

Answer:

y=3x+3

Step-by-step explanation:

(2,9)

x=2

y=9

-Slot these numbers into the equation y=mx+c

-Solve for c

y=3x+c

9=3(2)+c (We have substituted y for 9 and x for 2)

-Solve

9=6+c

(rearrange)

c+6=9

c=9-6

c=3

We have found our y-intercept (c)

Add this value into the original equation (replace the other y-intercept with your new value)

y=3x+3

P(0<X<55) = normalcdf(0,55,74,10) = 0.287164928 = 28.72% of students failed the course

Answer:

$ 80 000

Step-by-step explanation:

provident fund -- x

Wife -- 1/2 of x

Son -- 1/4 of x

Two brothers -- x - (x/2 - x/4)

Therefore, x - (x/2 - x/4) / 2 = 10 000

x = 80 000

Therefore, the amount of provident fund is $ 80 000

Thenks and mark me brainliest :)

Answer:

Angle 5 would be 119 degrees.

Step-by-step explanation:

This is because the angle that is 61 degrees and angle 5 are both supplementary angles. Supplementary angles would add up to 180 degrees and would lie on the same side of the line. So 180 minus 61 is 119.

Answer:

The expected number of red balls in the sample is 1.2857.

Step-by-step explanation:

The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

3 red balls in the sample:

This means that [tex]k = 3[/tex]

3 balls are drawn:

This means that [tex]n = 3[/tex]

Total of 3 + 4 = 7 balls:

This means that [tex]N = 7[/tex]

What is the expected number of red balls in the sample?

[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]

The expected number of red balls in the sample is 1.2857.

6 plus the 5 left in the parenthesis is 11

brainiest pls

Answer:

2069 grams

Step-by-step explanation:

Assume that the box itself is massless so the weight is only due to the spheres only. Calculate the volume of a solid sphere of radius 3 in:

Vout = (4/3)pi(3^3) = 36pi in^3

Now calculate the volume of a solid sphere of radius 2 in:

Vin = (4/3)pi(2^3) = (32/3)pi in^3

To calculate the volume of the hollow sphere, subtract Vin from Vout:

Vnet = Vout - Vin = (76/3)pi

Since the density of the plastic is 3.25 g/in^3, the mass of each hollow sphere is

m = (density) × Vnet = (3.25 g/in^3)×(76/3)pi

= 258.7 g

Since there are 8 spheres in a box, the total weight of the box is

M = 8m = 2069 grams

Answer:

1.106 inches squared 2. 60 inches cubed

Step-by-step explanation:

The surface area is just calculated like this 7.5*2*2 (because there are 2 faces) = 30 then 2*4*2= 16 then 4*7.5*2= 60 then you add them to get 106

For the second all you do is multiply the three values which gets you 60

would be amazing if you picked this as brainliest :)

Answer:

Step-by-step explanation:

.Find the surface area

(7,5*4) *2 + (7,5*2) *2 + (4*2) * 2 =

60+ 30+ 16 => 106 inch²

2.Find the volume

7,5 * 2*4 =>60 inch³

Answer:

[tex] \displaystyle23.125 \: \text{pounds}[/tex]

Step-by-step explanation:

we are given that,

in order to figure out the weight of the larger bicycle we can consider using equation

let the weight of the larger bicycle be L

according to the second condition

we acquire

[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]

to simplify the mixed fraction to improper fraction we can use the formula given by

[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]

by using the formula we get

[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]

simplify multiplication:

[tex] \displaystyle L =\frac{92.5}{4} [/tex]

simplify division:

[tex] \displaystyle L =23.125[/tex]

hence,

the larger bicycle weighs 23.125 pounds
