PLEASE HELP ASAP This Probability Distribution Shows Thenumber Of Times A Group Of People Takesselfies

Answers

Answer 1

Answer:

The probability is 0.29

Step-by-step explanation:

Firstly, we need to know the total number of retakes

That is simply the sum of the frequencies

we have this as;

27 + 29 + 18 + 14 + 12 = 100

so the probability of retaking exactly once will be the number of 1 retakes divided by total

That would be 29/100 = 0.29

Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment. I need help asap please

Answers

Answer:

See below

Step-by-step explanation:

Given

Initial number of bacteria = 800Growth rate = 3.2% = 1.032 times

Required equation:

B(t) = 800(1.032)^t, where B- number of bacteria, t- time in hours

The y-intercept is:

B(0) = 800*1.032^0 = 800The point (0, 800)

Bacteria population 35 in hours:

B(35) = 800*1.032^35 = 2409The point (35, 2409)

Answers

Answer:

Solution given:

we have

f(x)=x²-9x-36

let

y=x²-9x-36

when

x=0

y=-36

when

y=0

0=x²-9x-36

x²-12x+3x-36=0

x(x-12)+3(x-12)=0

(x-12)(x+3)=0

either

x=12

x=-3

So,

x and y intercepts are (-3,0)(12,0) and 0,-36)

Mr. Claussen needs a total of 15 pounds of ground beef to make hamburgers for a company picnic. He finds that 2 pounds of ground beef cost $4.40. At this rate, how much should Mr. Claussen plan on spending for the 15 pounds of ground beef? ....The answer : $33.00

Answers

Answer: $33.00

Step-by-step explanation:

Given

Mr. Claussen needs 15 Pounds of ground beef

It is stated that 2 pounds of beef cost $4.40

Using unitary method

1 Pound cost  [tex]\frac{4.4}{2}=\$2.2[/tex]

For 15 pounds it is

[tex]\Rightarrow 15\times 2.2=\$33[/tex]

Thus, he has to spend $33 for 15 pound meat

(Scroll Down for Answer!)

Step-by-step explanation:

3*y = 57 + 9 = 66

y = 66/3 = 22

x + 22 = 57

x = 57 - 22 = 35

Por lo tanto, los números son 35 and 22.

6. The swing set on the playgrounds is getting wobbly, and you have been asked to put outrigger boards to help stabilize it. If the crossbar of the swing is 10 feet off of the ground, the outrigger to be attached at a 40 degree angle, and you want to bury the outrigger boards 3 feet onto the ground, how long would the boards have to be? (Hint: the outrigger is the hypotenuse of a right triangle)

Answers

Answer:

[tex]X=18.6ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of swing's crossbar [tex]H=10ft[/tex]

Angle [tex]\theta=40 \textdegree[/tex]

Depth of outrigger [tex]d_=3ft[/tex]

Generally the equation for slant height l is mathematically given by

[tex]l=\frac{opposite}{sin\theta}[/tex]

Therefore

[tex]l=\frac{H}{sin\theta}[/tex]

[tex]l=\frac{10}{sin 40\textdegree}[/tex]

[tex]l=15.6ft[/tex]

Since the Depth of outrigger

[tex]d_=3ft[/tex]

Therefore Length of the board X

[tex]X=l+d[/tex]

[tex]X=15.6+3[/tex]

[tex]X=18.6ft[/tex]

A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?

Answers

Answer:

P(Y) = 2/10 = 1/5

Step-by-step explanation:

From the above question:

Total number of marbles = 10 marbles

Number of yellow marbles = 2 yellow marbles

Number of blue marbles = 4 blue marbles

Number of red marbles = 4 red marbles.

The probability of choosing a marble that is yellow is calculated as:

= P(Y) = Number of yellow marbles/Total number of marbles

P(Y) = 2/10

P(Y) = 1/5
