Answer:

12 minutes to 32 minutes

Step-by-step explanation:

just took exam

If the mean time is 22 minutes and the standard deviation is 5 minutes, 95% of the employees will have a travel time within 12 minutes and 32 minutes.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We know that the mean travel time is 22 minutes (µ = 22) and the standard deviation is 5 minutes (σ = 5).

Using the empirical rule, we know that  95% of the data will fall within 2 standard deviations of the mean.

Therefore, we need to find the interval that is 2 standard deviations away from the mean in both directions.

The lower end of the range would be:

µ - 2σ = 22 - 2(5) = 12 minutes

The upper end of the range would be:

µ + 2σ = 22 + 2(5) = 32 minutes

Therefore,  95% of the employees will have a travel time between 12 minutes and 32 minutes.

Given:

There are 3 cards, a 5 a 6 and a 7.

You pick a card at random. Without putting the first card back, you pick a second card at random.

To find:

The probability of picking a 5 and then picking a 6.

Solution:

We have,

Total number of cards = 3

Number of card of 5 = 1

So, probability of getting a card of 5 is:

[tex]P(5)=\dfrac{\text{Number of card of 5}}{\text{Total number of cards}}[/tex]

[tex]P(5)=\dfrac{1}{3}[/tex]

After this selection, the remaining number of cards is 2. So, probability of getting a card of 6 in second draw is:

[tex]P(6)=\dfrac{\text{Number of card of 6}}{\text{Total number of remaining cards}}[/tex]

[tex]P(6)=\dfrac{1}{2}[/tex]

Now, the probability of picking a 5 and then picking a 6 is

[tex]P(\text{5 then 6})=P(5)\times P(6)[/tex]

[tex]P(\text{5 then 6})=\dfrac{1}{3}\times \dfrac{1}{2}[/tex]

[tex]P(\text{5 then 6})=\dfrac{1}{6}[/tex]

Therefore, the probability of picking a 5 and then picking a 6 is [tex]\dfrac{1}{6}[/tex].

Answer: 50%

Step-by-step explanation:

From the question given, we are informed that a fish tank has sprung a leak at the bases of the tank and that 5% of the water is lost every minute

Based on the information given, the amount of water that is lost from the tank after ten minutes will be:

= 5% × 10

= 0.05 × 10

= 0.5

= 50%

This means that after 10minutes, 50% of the water will be lost.

Answer:

A. The singular enclosure would minimize cost because it requires 180 feet of fencing.

Step-by-step explanation:

Given

Single enclosure

[tex]Area = 2025ft^2[/tex] --- of square

Two adjacent enclosures

[tex]Dimension= 20ft\ by\ 40ft[/tex] ---- both rectangles

[tex]Divider = 40ft[/tex]

Required

Determine the true statement to minimize cost

Start by calculating the perimeter of the single enclosure.

Let

[tex]l \to[/tex] length of the enclosure (square shape)

So:

[tex]Area = l^2[/tex]

[tex]2025 = l^2[/tex]

Rewrite as:

[tex]l^2 = 2025[/tex]

Take square roots

[tex]l = 45[/tex]

The perimeter (P) is then calculated as:

[tex]P = 4l[/tex]

[tex]P = 4 * 45[/tex]

[tex]P_1 = 180ft[/tex]

Next, the perimeter of the two enclosures.

Let

[tex]l \to[/tex] length of the enclosure

[tex]w \to[/tex] width of the enclosure

[tex]l = 20[/tex]

[tex]w =40[/tex]

The perimeter of 1 enclosure is:

[tex]P = 2(l + w)[/tex]

[tex]P = 2(20 + 40)[/tex]

[tex]P = 2*60[/tex]

[tex]P = 120[/tex]

For 2 enclosures

[tex]P_2 =2 * P[/tex]

[tex]P_2 =2 * 120[/tex]

[tex]P_2 =240[/tex]

Remove the length of the divider

[tex]P_2 = 240 - 40[/tex]

[tex]P_2 = 200ft[/tex]

By comparison;

[tex]P_1 < P_2[/tex]

i.e.

[tex]180ft < 200ft[/tex]

Hence, the singular enclosure will minimize costs

Answer:

B ; C ; D

Step-by-step explanation:

Number of faces on a number cube = 6

Sample space = (1, 2, 3, 4, 5, 6)

P(1 then 0)

P(1) = 1/6 ; P(0) = 0

P(1 then 0) = 1/6 * 0 = 0

P(even number then odd number) :

P(even number) = 3/6 = 1/2

P(odd) = 3/6 = 1/2

P(even number then odd number) = 1/2 * 1/2 = 1/4

P(6 then 2) :

P(6) = 1/6 ; P(2) = 1/6 = 1/2

P(6 then 2) = 1/6 * 1/6 = 1/36

P(even number then 5) :

P(even) = 3/6 = 1/2

P(5) = 1/6

P(even number then 5) = 1/2 * 1/6 = 1/12

P(odd number then 2) :

P(odd) = 3/6 = 1/2

P(2) = 1/6

P(odd number then 2) = 1/2 * 1/6 = 1/12

Answer:

2

Step-by-step explanation:

First you need to factor your quadratic equation. You'll get (2x+1)(2x+1). Your two zeroes will be -1/2 and -1/2 with one being a, the other b. So then

a/b = (-1/2)/(-1/2)

and

b/a = (-1/2)/(-1/2)

Both reduce to 1. So a/b + b/a is 1+1=2

Answer:

180 degrees

Step-by-step explanation:

Given

[tex]Time = 5:00pm[/tex]

Required

The measure of the major arc, 30 minutes after

First, we calculate the time after 30 minutes

[tex]Time = 5:00pm +30\ mins[/tex]

[tex]Time = 5:30pm[/tex]

At 5:30pm, the hour and the minute hand will be directly opposite each other.

In other words, the hands divide the time into two equal parts (180 degrees each)

At this point, there is no major or minor arc as both sides have the same measurement

Hence, the measure of the arcs is 180 degrees
