Answer: C.

Step-by-step explanation:

If ABCD gets rotated 180ᴼ, you will be able to see the reflection of ABCD to A’B’C’D’. Then just reflect across the x-axis (horizontal) to transform ABCD onto A’B’C’D’.

The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscriber

Anna71 [15]

Answer: A. The expression $(1.05)^{6t}$ reveals the approximate rate of increase in the number of subscribers if measured six times a year.

Step-by-step explanation:

Here, The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscribers after t years.

$f(t) = 13,000(1.34)^t$

where $(1.34)^t$ represents rate of increase in the number of subscriber.

If rate is measured six times a year

then the number of subscriber, $f(6t)= 13000(1+0.34/6)^{6t}$

$f(6t) = 13000( 1+0.05)^{6t}= 13000(1.05)^{6t}$ ( approx)

Thus, when we measure increment in six times a year then the rate rate of increase in the number of subscribers= $(1.05)^{6t}$

Therefore Option A is correct.

Note: Option B) is incorrect because rate of increase in the number of subscribers if measured three times a year = $13000(1.11)^{3t}$ ( approx)

Option C) is incorrect because rate of increase in the number of subscribers if measured four times a year = $13000(1.085)^{4t}$ ( approx)

Option D) is incorrect because rate of increase in the number of subscribers if measured two times a year = $13000(1.17)^{2t}$ ( approx)

The football team has a total of 20 jerseys. There are 4 medium-sized jerseys. What percent of the jerseys are medium-sized jers

DanielleElmas [232]

20%

Because Suppose x% of 20 is 4

That is
x100×20=4
or
x5=4

—> =4×5=20

So 20% of 20 is 4

The frequency table shows the results of tossing a number cube 50 times. Which statement

Paul [167]

Answer:

Option (1) is the correct option.

Step-by-step explanation:

From the given frequency table,

Option (1).

Tossing an even number is more likely than tossing an odd number.

Frequencies of tossing even numbers 2, 4, 6 = 10, 10, 9

Frequencies of tossing odd numbers 1, 3, 5 = 8, 6, 7

Which shows frequencies of tossing even numbers are more.

Therefore, Option (1) is correct.

Option (2)

The number 2 will be the next number tossed.

Since it is unpredictable, therefore, this option is incorrect.

Option (3)

Number 4 is half as likely to be tossed as the number 3.

Frequency of tossing number 3 = 6

Frequency of tossing 4 = 10

Frequency of tossing 3 is not the half of tossing 4.

Therefore, Option (3) is incorrect.

Option (4)

Probability of tossing the number 2 = $\frac{\text{Frequency of tossing 2}}{\text{Total frequency}}$

= $\frac{10}{8+10+6+10+7+9}$

= $\frac{10}{50}$

= $\frac{1}{5}$

Therefore, option (4) is incorrect.

Write one digit on each side of 10 to make a four digit multiple of 72. How many different solutions does this problem have? The

Viefleur [7K]

If we write 4 to each side of 10, we will get a four digit number 4104, which is a multiple of 72.

To find out other possible solutions, first start with 1 in front of 10.

Now, divide 110 by 72.

The remainder is 38.

We are going to put one more digit after 10.

So, let us check if there is any three digit number whose first two digits are 38 and which is a multiple of 72.

There is no such number since 5 × 72 = 360 and 6 × 72 = 432.

So, there is no four digit number whose first three digits are 110 and which is a multiple of 72.

If we try like this, we can find 4104 is the only solution.
