Step-by-step explanation:

The probability that takes exactly four interviews to find the first applicant with previous experience will be 0.3845.

Frequency distribution of the percentage of successful outcomes that might occur in a certain number of trials with the same chance of success. If X~B(n, p), then the probability is given as

[tex]\rm P(X=x) = \ ^nC_x \times p^x \times (1-p)^{n - x}[/tex]

At a big pharmaceutical company, historically, just 35% of applicants for an internship in statistical programming had prior computer software experience. Assume that candidates are chosen at random and questioned one at a time.

p = 0.35

Then the probability is given as,

P = ⁴C₁ x (0.35)¹ x (1 - 0.35)³

P = 0.3845

The probability that takes exactly four interviews to find the first applicant with previous experience will be 0.3845.

She is wrong. Since is .5, you round up to the nearest tenth. So it is 2.0

Step-by-step explanation:

If student has a container with a volume of 2.5 liters. She estimates the volume to be 2.4 liters. Then by 4% the student's estimate off

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The container of a student has a volume of 2.5 liters.

She estimates the volume to be 2.4 liters

We need to find the percent of  student's estimate off.

To find this we have to find the difference of 2.5 and 2.4

2.5-2.4=0.1

Now divide zero point one divided by two point five

0.1/2.5

0.04

Multiply with hundred

0.04×100=4%

Hence 4 % is the students estimate off

Answer:

Number of black counters = 5

Step-by-step explanation:

Let,

x be the total number of counters

Number of red counters = [tex]\frac{1}{3}x[/tex]

Number of black counters = [tex]\frac{1}{6}x[/tex]

Number of green counters = 15

Now,

Red counters + Black counters + Green counters = Total counters

[tex]\frac{1}{3}x+\frac{1}{6}x+15=x\\\\\frac{2x+x+90}{6}=x\\\\3x+90 = 6x\\90 = 6x-3x \\90 = 3x\\3x = 90[/tex]

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{90}{3}\\x=30[/tex]

Number of black counters = [tex]\frac{1}{6}*30[/tex] = 5

Hence,

Number of black counters = 5

Answer:

Improper fraction: 23/4

Mixed number: 5 3/4

Answer:

5 3/4

Step-by-step explanation:

how many times does 4 go into 23? well 4×5=20, which seems like too little, so we'll try 4×6=24,

but that's too much so were sticking with the 5. So 5 is the first number

then since 4 times 5 is 20. but you have 23, there are 3 extra numbers

So you make them into a fraction: 3/4

So the answer is 5 3/4

also 23/4 is the improper fraction, 5 3/4 is the mixed number

Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?

Answer:

The expression can be rewritten by combining like terms such as:

[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]

Step-by-step explanation:

Like term:

We know that like terms are those terms with:

For example,

2x and 4x are the like terms. Both have the same variables and the same power of the variable.

Similarly, 2x³ and 4x³ are like terms. Both have the same variables and the same exponents of the variables.

Please note that the like terms may have different coefficients of the variables.

NOW, REWRITING THE EXPRESSION BY COMBINING LIKE TERMS

Given the expression

[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)[/tex]

Here in the parentheses:

as

Combining like terms in the parentheses

[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]

Therefore, the expression can be rewritten by combining like terms such as:

[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]

Answer: 17.3 in 2

Step-by-step explanation

The approximate area of the shaded sector is 34.6 in2.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

Angle = 145°

Now,

The area of a sector of a circle is given by the formula A = (θ/360)πr2, where θ is the central angle in degrees and r is the radius of the circle. In this case, θ = 145° and r = 7 in.

Plugging these values into the formula, we get: A = (145/360)π(7)^2. Simplifying, we get: A = 0.4028π(49). Using a calculator, we get: A ≈ 34.6 in2.

Therefore, by the area the answer will be 34.6 in2.

Answer:

a) The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.

b) It means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

a)

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.797

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.797\frac{1.8}{\sqrt{25}} = 1[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 24.1 - 1 = 23.1 mg

The upper end of the interval is the sample mean added to M. So it is 24.1 + 1 = 25.1 mg

The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.

b)

The interval means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

Rectangular Coordinates

The lower vertices of a rectangular welcome sign in Mr. Brettler's gym are (9,-3) and (-6,-3).

Note these two vertices are 3 units below the x-axis. We know the sign is 5-foot tall, so the y-coordinates of the two upper vertices should be -3+5=2.

The upper vertices of the sign on the grid are (9,2) and (-6,2).

Answer:

[tex]35[/tex]

Step-by-step explanation:

The constraints are

The red line represents the function

[tex]y\leq \dfrac{1}{3}x+1[/tex]

At [tex]y=0[/tex]

[tex]0=\dfrac{1}{3}x+1\\\Rightarrow -1=\dfrac{1}{3}x\\\Rightarrow x=-3[/tex]

At [tex]x=0[/tex]

[tex]y=0+1\\\Rightarrow y=1[/tex]

Two points are [tex](-3,0),(0,1)[/tex]

The blue line represents the function

[tex]5\geq y+x[/tex]

at [tex]y=0[/tex]

[tex]5=x[/tex]

at [tex]x=0[/tex]

[tex]y=5[/tex]

Two points are [tex](5,0),(0,5)[/tex]

The other two constraints are [tex]x\geq 0[/tex], [tex]y\geq 0[/tex]. So, the point has to be in the first quadrant

From the graph it can be seen there are two points where the function will be maximum let us check them.

[tex](3,2)[/tex]

[tex]7x-2y=7\times 3-2\times 2=17[/tex]

[tex](5,0)[/tex]

[tex]7x-2y=7\times 5-2\times 0=35[/tex]

So, the maximum value of the function is [tex]35[/tex].
