x= [
(smaller value)
X

(larger value)

Answers

Answer 1

Answer:

x = 2   or  x = 4

Step-by-step explanation:

Solve:   2 log x = log 2 + log(3x - 4)

log (x^2) =  log 2 + log (3x - 4)

log (x^2) = log [2*(3x - 4)]

x^2 =  2*(3x - 4)

x^2 = 6x - 8

x^2 - 6x + 8 = 0

factor:

(x - 2 )(x - 4) = 0

x = 2   or  x = 4

If the APR of a savings account is 4.8% and interest is compounded monthly,

what is the approximate APY of the account?

O A. 1.05%

O B. 10.49%

O C. 4.91%

O D. 4%

Answers

Answer:

  C.  4.91%

Step-by-step explanation:

The effect of frequent compounding is to increase the nominal interest rate by a small factor. For interest rates in a practical range (<20%/year), the effective increase in rate will be approximately half the original interest rate.

Approximation

For an interest rate of 4.8%, we expect the compounding to increase it by less than 2.4%. The maximum effective rate due to compounding is approximately (4.8%)(1 +2.4%) ≈ 4.91%.

Exact computation

For nominal annual rate r compounded n times per year, the effective annual rate is ...

  r' = (1 +r/n)^n -1

For r = 0.048 and n = 12, this becomes ...

  r' = (1 +0.048/12)^12 -1 = 1.004^12 -1 ≈ 1.049070208 -1 ≈ 4.91%

__

Additional comment

After you have worked with interest compounding for a bit, you realize compounding increases the effective rate by a small amount. That means the value will be more than 4.8% (eliminating choices A and D), but certainly will not be as high as 10% (eliminating choice B). The only reasonable choice is C, which happens to be the correct one.

The circumferences of WNBA basketballs follow a normal distribution where mean = 29.0 ; and standard deviation = 0.1 inches.

What proportion of WNBA basketballs are SMALLER than 29.1 inches? Round to the nearest percent

Answers

Answer:

[tex]P(X<29.1)=P(\frac{X-\mu}{\sigma}<\frac{29.1-\mu}{\sigma})=P(Z<\frac{29.1-29}{0.1})=P(z<1)[/tex]

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

[tex] P(z<1) =0.8413[/tex]

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

84%

Step-by-step explanation:

Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(29,0.1)[/tex]  

Where [tex]\mu=29[/tex] and [tex]\sigma=0.1[/tex]

We are interested on this probability

[tex]P(X<29.1)[/tex]

And the best way to solve this problem is using the normal standard distribution and the z score given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

If we apply this formula to our probability we got this:

[tex]P(X<29.1)=P(\frac{X-\mu}{\sigma}<\frac{29.1-\mu}{\sigma})=P(Z<\frac{29.1-29}{0.1})=P(z<1)[/tex]

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

[tex] P(z<1) =0.8413[/tex]

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

3 parts: List the ratios for using angle A as the angle of reference reduce when necessary

Sin A= Cos A= Tan A=

Answers

Answer:

[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]

Step-by-step explanation:

The sine of an angle in a right triangle is the ratio of the side across from the angle with the hypotenuse of the triangle (the hypotenuse is the side across from the right angle). In this case, the sine of angle A, shortened to [tex]\sin{A}[/tex], is [tex]21/29[/tex].

Cosine is short for "complementary sine." If the angles A + C = 90, the cosine of A is equal to the sine of C, since A and C are complementary. So [tex]\cos{A}=\sin{C}=20/29[/tex]. Notice that this ratio is the same as the ratio of the side adjacent to angle A (AB), to the hypotenuse.

The tangent is the ratio of the side opposite an angle to the side adjacent to it. Here, [tex]\tan{A}=21/20[/tex]. So, our trig ratios for this angle are

[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]

Step-by-step explanation:

₄C₂ means that we're trying to see how many ways we can pick 2 things out of a group of 4. We have 4 options for our first pick and 3 for our second, so that gives us a total of 4 · 3 = 12 ways of choosing.

Now, the "C" in ₄C₂ is short for "combinations." Order doesn't matter where combinations are concerned. Let's say the set we're choosing from is the set of the letters A, B, C, and D. Here are all the ways we can choose two different letters from that list:

AB, AC, AD, BA, BC, BD, CA, CB, CD, DA, DB, DC

Notice that, for each pair, we have another in the set that contains the same letters: AB and BA, AC and CA, BD and DB... If order doesn't matter, we can cut all of those second pairs, giving us 12 / 2  = 6 total combinations.

The vertices are 4 units to the left and right of the center.

The foci are units to the left and right of the center on the major axis.  

The directrices are vertical lines.

Step-by-step explanation:

The statements 2, 3 and 4 are correct. The ellipse graph shows that the foci are units to the left and vertices are 4 units to the left. The center os the ellipse is not at the origin (0,0) so the statement 1 is not correct. Ellipse is an oval shape with 2 other points known as foci.

The first table that Cory designs will seat 8 people. If the diameter is 5 feet, what is the area? The area in terms of pi is Pi ft2. Approximating 3.14 for Pi, the area rounded to the nearest tenth is ft2.

Answers

Final answer:

The area of a circle with a diameter of 5 feet is calculated using the formula A = πr². Halving the diameter to find the radius, then squaring it, multiplying by π (approximated as 3.14), and rounding to the nearest tenth, gives an area of 19.6 ft².

Explanation:

The student's question involves finding the area of a circle with a given diameter where the circle is the table's top designed by Cory. To find the area, one must use the formula A = πr², where A is the area, π (pi) represents the mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Since the diameter of the table is 5 feet, the radius will be half of that, which is 2.5 feet. Plugging this into the formula, we get A = π(2.5²) or A = π(6.25). Assuming π as 3.14, we approximate the area to 19.6 ft² after rounding to the nearest tenth.

Final answer:

To find the area of Cory's circular table with a 5-foot diameter, we calculate the radius as half the diameter (2.5 feet) and use the area formula A = πr² to get approximately 19.6 square feet when using 3.14 for pi.

Explanation:

The question asks us to find the area of a circular table that Cory designs, which seats 8 people and has a diameter of 5 feet. To calculate the area of a circle, we use the formula A = πr², where 'A' is the area, 'π' (pi) is a mathematical constant approximately equal to 3.14, and 'r' is the radius of the circle.

First, we need to find the radius, which is half of the diameter, hence the radius is 5 feet / 2 = 2.5 feet. Using the formula, the area in terms of pi is A = π(2.5 ft)². When we approximate π as 3.14, the area rounded to the nearest tenth in square feet is 3.14 * (2.5 ft)² = 19.625 ft², which can be rounded to 19.6 ft².

a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².

b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).

You require space to service 65 vehicles at any one time. Will a facility measuring 165 ft. by 130 ft. be adequate if each vehicle requires 300 sq.ft.?

Answers

Answer:

The facility will be adequate for the task.

Step-by-step explanation:

You require space to service 65 vehicles at any one time and each vehicle requires 300 ft² of space. This means, the 65 vehicles will require space of:

65 * 300 = 19500 ft²

A facility measuring 165 ft. by 130 ft is being considered. The area of the facility is:

165 * 130 = 21450 ft²

Since the space of the facility is larger than the space needed for the 65 vehicles, the facility will be adequate for the task.

Step-by-step explanation:

Question 1:

All of the outcomes are not equally likely because there is a lot of variation between the relative frequencies of the different landing positions.

As we can see from the data, the cup will most likely land sideways, then backwards, then upright. Since there is a lot of variation between the number of times this happens, we know this isn't just because of the random factor, but because there is a higher probability of it landing on its side. Additionally, the huge differences between the numbers tell us that the 3 outcomes are not equally likely. That removes option A and B. We know it isn't option C because the relative frequency of it landing sideways is not the lowest, but the highest. (Upwards: 9/60= 0.15= 15%, Upside down: 15/60= 0.25= 25%, Sideways: 36/60= 0.6= 60%) Therefore, option D is the correct answer.

Question 2:

Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

We can look at the table, and understand the the relative frequencies of these outcomes will all be similar.

We can calculate it to make sure.

L: 10/40= 0.25= 25%

E: 11/40= 0.275= 27.5%

A: 9/40= 0.225= 22.5%

P: 10/40= 0.25= 25%

As you can see, the relative frequency of all these options is similar, indicating that this is a fair model.

Question 3:

Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Once again, when looking at the tables, we see that all outcomes occur a similar number of times, meaning that the model is most likely fair.

To make sure, we can calculate the relative frequencies.

Green: 12/50= 0.24= 24%

Pink: 9/50= 0.18= 18%

Yellow: 11/50= 0.22= 22%

Blue: 10/50= 0.2= 20%

Red: 8/50= 0.16= 16%

Although these frequencies aren't as similar as the previous model, I would still deem them similar enough for the model to be considered fair.
