The probability that a randomly selected person who tested positive for the flu is vaccinated  is 465/2321.

Probability determines the chances that an event would happen. The odds  the event occurs is 1 and the odds that the event does not occur is 0.

The probability that a randomly selected person who tested positive for the flu is vaccinated  = number of people who tested positive and have been vaccinated / total number of people

Answer:

We can conclude that there is significant evidence that the drug improves short term memory.

Step-by-step explanation:

Given the sample data : 8, 9, 10, 6, 8, 7, 9, 7.

The sample mean, xbar = Σx / n

Sample standard deviation :

√Σ(x - xbar)²/ n-1)

Xbar = 8

Sample size, n = 8

Standard deviation, s = 1.31

H0 : μ = 6

H0 : μ > 6

The test statistic :

(xbar - μ) ÷ (s/√(n))

(8 - 6) / (1.31 / √8)

2 /0.4631549

Test statistic = 4.318

Decision region :

Reject H0 ; if Pvalue < α

α = 0.05

Pvalue from Tscore calculator :

df = n - 1 ; 8 - 1 =7

Pvalue(4.318, 7) = 0.001744

Pvalue < α ; We reject H0 ; and conclude that there is significant evidence that the drug improves short term memory.

Answer:

The z-score for the statistics test grade is of 1.11.

The z-score for the calculus test grade is 7.3.

Due to the higher z-score, the student performed better on the calculus test relative to the other students in each class

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

The grade with the higher z-score is better relative to the other students in each class.

Statistics:

Mean of 79 and standard deviation of 4.5, so [tex]\mu = 79, \sigma = 4.5[/tex]

Student got 84, so [tex]X = 84[/tex]

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{84 - 79}{4.5}[/tex]

[tex]Z = 1.11[/tex]

The z-score for the statistics test grade is of 1.11.

Calculus:

Mean of 69, standard deviation of 3.7, so [tex]\mu = 69, \sigma = 3.7[/tex]

Student got 96, so [tex]X = 96[/tex]

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{96 - 69}{3.7}[/tex]

[tex]Z = 7.3[/tex]

The z-score for the calculus test grade is 7.3.

On which test did the student perform better relative to the other students in each class?

Due to the higher z-score, the student performed better on the calculus test relative to the other students in each class

Answer:

1. 54 = 0.6x

2. 90 dollars (see below)

Step-by-step explanation:

54 = 0.6x

0.6 is the decimal equivalent of 60%

Divide both sides by 0.6:

54/0.6 = 0.6x/0.6

90 = x

Answer:

3800 tickets

Step-by-step explanation:

we are given that,

total people seated:266

yet to come:93%

so the percentage of people who have arrived is 100%-93%=7%

and one ticket for each people

therefore,

[tex] \displaystyle \begin{array}{ccc} \displaystyle \rm7\% \quad \text{People} \implies266 \: \text{tickets} \\ \displaystyle100 \%\: \quad \imath \imath \implies \frac{266}{7\%} \: \: \: \: \imath \imath \\ \\ \qquad \displaystyle \qquad\rm as \: \% = \frac{1}{100} \longleftarrow \frac{266}{ \dfrac{7}{100} } \\ \\ \displaystyle \rm \: by \: simplifying \: complex \: fraction\longleftarrow 266 \times \frac{100}{7} \\ \rm reduce \: fraction \longleftarrow 38 \times 100 \\ \rm simplify \:multiplication \longleftarrow3800\end{array}[/tex]

hence,

3800 tickets were sold for the movie

Answer:

Solutions given:

[100%-97%]=266people

7% =266people

Each people is 1 ticket.

266 people =266tickets

so

7% of people=266ticket

100% of people =266/7×100=3800tickets

3800tickets were sold for the movie

Answer:

t = 45d

Step-by-step explanation:

Number of days = d

Number of minutes = t

Number of minutes per day = 45 minutes

Total number of minutes of practice after d number of days will be :

t = number of minutes per days * Number of days

t = 45 * d

t = 45d

Answer:

A = 5 ounces

B = 1 ounces

C = 4 ounces

Step-by-step explanation:

The 3 foods contain exactly 1800 calories but food A is 100 calories, food B is 500 calories and food C is 200 calories. Thus;

100A + 500B + 200C = 1800 - - - (eq 1)

The 3 meals allows exactly 75 grams of protein while A is 5 grams, B is 6 grams, C is 11 grams.

Thus;

5A + 6B + 11C = 75 - - - (eq 2)

The 3 meals allows exactly 5650 milligrams of vitamin C while A is 400 mg, B is 2050 mg and food C is 400 mg. Thus;

400A + 2050B + 400C = 5650 - -(eq 3)

Solving the 3 equations simultaneously online, we have;

A = 5 ounces

B = 1 ounces

C = 4 ounces

Food A is 5 ounces, Food B is 1 ounce, and Food C is 4 ounces and this can be determined by forming the linear equation in three variables.

Given :

Let the total amount of Food A be 'A', total amount of Food B be 'B', and the total amount of Food C be  'C'.

The linear equation that represents total calories in each food is:

100A + 500B + 200C = 1800  

[tex]\rm A =\dfrac{ 1800 - 500B-200C}{100}[/tex]      

[tex]\rm A =18 - 5B-2C[/tex]       --- (1)

The linear equation that represents total protein in each food is:

5A + 6B + 11C = 75    ---- (2)

The linear equation that represents total Vitamin C in each food is:

400A + 2050B + 400C = 5650   --- (3)

Now, substitute the value of 'A' in equation (2).

[tex]\rm 5(18-5B-2C)+6B+11C=75[/tex]

Simplify the above equation.

90 - 25B - 10C + 6B + 11C = 75

C - 19B = -15

C = 19B - 15     ---- (4)

Now, substitute the value of 'C' in equation (1).

A = 18 - 5B - 2(19B - 15)

A = 18 - 5B - 38B + 30

A = 48 - 43B  --- (5)

Now, substitute the value of A and C obtains in equations (4) and (5) in equation (3).

A = 5 ounces

B = 1 ounce

C = 4 ounces

Answer:

x = 35

y = 100

Step-by-step explanation:

∠AEB and ∠DEC are vertical angles because they are opposite each other; they are also equal because of this. We can write an equation to model the situation:

∠AEB = ∠DEC

50° = x° + 15°

x = 35

∠AEB and ∠AED are supplementary because the form a line; this means they add up to 180°

∠AEB + ∠AED = 180°

50° + y + 30° = 180°

y + 80°  = 180°

y = 100

Number of seeds in each cup = 5 seeds in each cup

Step-by-step explanation:

Given:

Total number of seeds Liam has = 60 seed

Total number of plastics cup = 12 cups

Find:

Number of seeds in each cup

Computation:

Number of seeds in each cup = Total number of seeds Liam has / Total number of plastics cup

Number of seeds in each cup = 60 / 12

Number of seeds in each cup = 5 seeds in each cup

Answer:

A. Transform circle C with a dilation that has center  C and scale factor s.

Step-by-step explanation:

Given

Circle C

[tex]radius = r[/tex]

Circle D

[tex]radius = s[/tex]

Required

Map C to D

From the question, we can assume that:

[tex]r \ne s[/tex]

This implies that options c and d are false because when an object is translated from one point to another, the size of the object remains unchanged.

To map C onto D,

1) C has to be dilated from its own center C

2) The scale of dilation will be equal to the radius of D (i.e. s)

Hence, (A) is correct

Answer:

It's C

Transform circle C with the translation that maps point Conto point D.

Answer:

The searchlight should be 6.25ft deep

Step-by-step explanation:

Given

[tex]Across = 20ft[/tex]

[tex]Base = 4ft[/tex]

Required

The depth of the searchlight

[tex]Across = 20ft[/tex] implies that the search light span 10 units to either side of the x-axis

[tex]Base = 4ft[/tex] implies that the search light span 4 units to the y-axis

The attached image illustrates the revolution.

From the attached image, the endpoints of the searchlight is:

[tex](x,y) = \{(-10,4), (10,4)\}[/tex]

The depth (a) of the search light is calculated using:

[tex]x^2 = 4ay[/tex]

Make a the subject

[tex]a = \frac{x^2}{4y}[/tex]

Substitute -10 or 10 for x and 4 for y

[tex]a = \frac{(-10)^2}{4*4}[/tex]

[tex]a = \frac{100}{16}[/tex]

[tex]a = 6.25ft[/tex]
