Xanthe is a client that Josie trains. Xanthe’s MHR is 190 beats per minute. Her target heart rate is 70% of her MHR. What is Xanthe’s target heart rate?

Answers

Answer 1

Answer: The answer is 133 beats per minute.

To calculate this, we will use proportion.
If 190 beats per minute are 100%, how many beats per minute are 70%:
190 bpm : 100% = x : 70%
$(190 bpm)/(100) = (x)/(70)$
$(70 * 190bpm)/(100) = x$
$x = 133 bpm$

Thus, Xanthe's target heart rate is 133 beats per minute.

A conditional relative frequency table is generated by row from a set of data. The conditional relative frequencies of the two categorical variables are then compared.If the relative frequencies are 0.48 and 0.52, which conclusion is most likely supported by the data? A.) There is likely an association between the categorical variables because the relative frequencies are similar in value. B.) An association cannot be determined between the categorical variables because the relative frequencies are similar in value. C.) An association cannot be determined between the categorical variables because the relative frequencies are not similar in value. D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50.

To begin an indirect proof you assume the converse of what you intend to prove is true

False. The converse may be either true or false, depending on what the original statement is, so assuming the converse would be pointless.

Answer:

false

By rounding both numbers to the nearest hundred, we can estimate a sum of 400. Using the tool to model 325 + 169, we find the exact sum is: A) 400 B) 500 C) 494 D) 495

Answers

To estimate the sum of 325 and 169 by rounding to the nearest hundred, we round both numbers:

325 rounds to 300
169 rounds to 200

Now, let's add these rounded numbers:

300 + 200 = 500

So, the estimated sum is 500.

Now, to find the exact sum of 325 + 169:

325 + 169 = 494

So, the exact sum is 494.

The correct answer is C) 494.

Write an equation for a polynomial function that has zeros of {3,2}

Answers

Answer:

f(x) = x² - 5x + 6

Step-by-step explanation:

There are two roots:

x = 3 and x = 2

The function is:

f(x) = (x - 3)(x - 2)
= x² - 5x + 6

Shirts-2-Go sells t-shirts for a base price of $12 per shirt plus a fixed fee of $3 shipping and handling for the whole order. Shirts PLUS sells t-shirts for a base price of $8 per shirt plus a fixed fee of $23 shipping and handling for the whole order. Let x represent the number of shirts ordered and let y represent the total cost of the order.y = 12x + 3

y = 8x + 23

How many shirts would you have to purchase for the total cost to be the same at both companies?
