Answer:

Probability that 32 or more from this sample used Internet Explorer as their browser is 0.9015.

Step-by-step explanation:

We are given that according to Net Market Share, Microsoft's Internet Explorer browser has 53.4% of the global market.

A random sample of 70 users was selected.

Let \(\hat p\) = sample proportion of users who used Internet Explorer as their browser.

The z score probability distribution for sample proportion is given by;

                            Z  =  \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\)  ~ N(0,1)

where, p = population proportion of users who use internet explorer = 53.4%

           \(\hat p\) = sample proportion = \(\frac{32}{70}\) = 0.457

           n = sample of users = 70

Now, probability that 32 or more from this sample used Internet Explorer as their browser is given by = P( \(\hat p\) \(\geq\) 0.457)

      P( \(\hat p\) \(\geq\) 0.457) = P( \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) \(\geq\) \(\frac{0.457-0.534}{\sqrt{\frac{0.457(1-0.457)}{70} } }\) ) = P(Z \(\geq\) -1.29)

                            = P(Z \(\leq\) 1.29) = 0.9015

The above probability is calculated by looking at the value of x = 1.29 in the z table which has an area of 0.9015.

Answer:

197

Step-by-step explanation:

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!

Day 1: 100 (3 tagged)

Day 2: 97 (3 tagged)

100+97=197

or

Day 1: 100 (3 tagged)

Day 2: 100 (3 tagged)

100+100= 200

200-3=197

Answer, 197 fish.

Answer: 31.7

Step-by-step explanation:

Do 16 plus 15.7 is 31.7 you added wrong.

Answer:

\(31.7\)

Step-by-step explanation:

The perimeter is the line forming the boundary of the figure.

Combining the two curved parts of the perimeter we obtain a circle with a diameter of 5 in. The perimeter (P) of a circle is calculated as follows:

\(P=\pi D\)

where D is the diameter. Then, the perimeter of the curved part is found replacing D = 5 in, as follows:

\(P^{1} =\pi~ .~5\\\)

\(P^{1} = 15.7~ in\)

To find the perimeter of the whole figure we need to add the two straight segments of length 8 in, that is,

\(P=15.7+8+8\\P=31.7\)

Hence the Answer is 31.7

Answer: \(1\frac{8}{9}\)

Step-by-step explanation:

i'm assuming the fraction is \(\frac{17}{9}\) correct? First you would have to find out how many times 9 can be multiplied to get as close to 17. Since it can only go one time, subtract 9 from 17, then add the one next to it which would get you the mixed number of  \(1\frac{8}{9}\)

Answer:

-15.875

Step-by-step explanation:

First, we can sum up the first 5 terms.

-8 + (-4) = -12

-12 + (-2) = -14

-14 + (-1) = -15

-15 + (-1/2) = -15.5

Next, we can find a pattern in the data. We can tell that the next number is one half of the current number. For example, -4 is one half of -8. To find the next number, we simply multiply our current number by one half. Thus, the sixth number is -1/4 and the seventh is -1/8. Adding these to our current total, we have

-15.5 - 1/4 = -15.75

-15.5 - 1/8 = -15.875 as our answer

By using scale and prοpοrtiοn, the dimensiοns οf the actual painting are 144 inches² by 216 inches².

Scale refers tο the relatiοnship between the dimensiοns οf a scaled οbject and the cοrrespοnding dimensiοns οf the οriginal οbject. If an οbject is scaled dοwn tο half its οriginal size, then the dimensiοns οf the scaled οbject will be half οf the dimensiοns οf the οriginal οbject.

Prοpοrtiοn, οn the οther hand, refers tο the relatiοnship between twο οr mοre quantities that have the same ratiο. In οther wοrds, if twο quantities are in prοpοrtiοn, then their ratiο is cοnstant.

Tο find the dimensiοns οf the actual painting, we need tο "undο" the 6:1 scale.

If the scaled painting is 6 times smaller than the actual painting, then the actual painting is 6 times larger than the scaled painting.

Sο we can find the actual dimensiοns by multiplying the scaled dimensiοns by 6:

Actual width = 24 inches x 6 = 144 inches

Actual height = 36 inches x 6 = 216 inches

Therefοre, the dimensiοns οf the actual painting are 144 inches² by 216 inches².

Answer:

0.42

Step-by-step explanation:

To solve the problem, we need to add the probability of picking a club to the probability of picking a face card, and then subtract the probability of picking a club that is also a face card (because we would have counted it twice).

There are 13 clubs in a standard deck, so the probability of picking a club is 13/52 or 0.25.

There are 12 face cards (4 jacks, 4 queens, and 4 kings) in a standard deck, so the probability of picking a face card is 12/52 or 0.23.

However, there are 3 cards that are both clubs and face cards (the jack of clubs, queen of clubs, and king of clubs), so we need to subtract the probability of picking one of those cards. There are 3 of them out of 52 total cards, so the probability of picking a club that is also a face card is 3/52 or 0.06.

Therefore, the probability of picking a club OR a face card is:

0.25 + 0.23 - 0.06 = 0.42 (rounded to two decimal places).

So the answer is 0.42.

Answer:

Step-by-step explanation:

Equation for a circle of radius r, centered at (h,k):

(x-h)² + (y-k)² = r²

The coordinates of the center and the measure of the radius for a circle given are center = (3,7), radius = √2.

A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the center. A circle is also the set of all points that are equidistant from the center.

Given is an equation of a circle, we need to find coordinates of the center and the measure of the radius for a circle,

The equation of the circle =

(x - 3)² + (y - 7)² = 2

The standard equation for a circle of radius r, centered at (h,k):

(x-h)² + (y-k)² = r²

Comparing both we get,

(h, k) = (3, 7)

r² = 2

r = √2

Hence, the coordinates of the center and the measure of the radius for a circle given are center = (3,7), radius = √2.

Answer:

5π > 15

Step-by-step explanation:

Testing the First expression:

6/2π  > 1

the denominator can be rewritten as:

6 / 6.28 > 1

Which is NOT true since the quotient of 6/6.28 is less than 1

Testing the second expression:

5π > 15

This expression can be rewritten as:

5*(3.14) > 5*3

After dividing both sides by 5, we can clearly see that the equation is true:

3.14 > 3

So, this equation is true

Testing the third Equation:

4π - 2 < 10

We can rewrite this equation as:

4(3.14)-2 < 10

Simplifying the LHS

10.56 < 10

We can see that this equation is NOT true

Testing the Fourth equation:

π + 9 < 12

Replacing the value of pi

3.14 + 9 < 12

12.14 < 12

We can see that this equation is also NOT true

Jessica would have to drive 20 miles for the cost to rent a moving truck for one day to be the same at Rentals Plus and Speedy Move.

Let's assume the number of miles driven is represented by 'm'. The cost of renting a moving truck for one day at Rentals Plus can be calculated using the equation:

Cost at Rentals Plus = $5.24 + $4.46 * m

Similarly, the cost of renting a moving truck for one day at Speedy Move can be calculated using the equation:

Cost at Speedy Move = $85.24 + $0.46 * m

To find the number of miles that makes the costs equal, we can set up the equation:

$5.24 + $4.46 * m = $85.24 + $0.46 * m

By rearranging the equation, we can solve for 'm':

$4.46 * m - $0.46 * m = $85.24 - $5.24

$4 * m = $80

m = $80 / $4

m = 20

Therefore, Jessica would have to drive 20 miles for the cost to rent a moving truck for one day to be the same at Rentals Plus and Speedy Move.

The polynomial 9 · x² - 6 · x - 4 = - 5 has a discriminant equal to 0 and two same real roots.

Quadratic equations are polynomials of the form:

y = a · x² + b · x + c

Where:

The discriminant is a real number determined by the following formula:

D = b² - 4 · a · c

There are three cases for discriminants:

First, write the polynomial in standard form:

9 · x² - 6 · x + 1 = 0

Second, calculate the value of the discriminant:

D = (- 6)² - 4 · 9 · 1

D = 36 - 36

D = 0
