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%



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

The Null hypothesis says mean height is 174.1cm
The alternative hypothesis negatea the null hypothesis :
Possible conclusions that can be made about the Null hypothesis. After utilizing the tbe various statistical procedures, we can either stand by the Null hypothesis or we reje t this null Hypothesis.
From the question above, supporting tbe claim that the mean height of men is equal to 174.1 cm is impossible as the expression represents the null claim. Statistical test are only used to support an alternative claim whereby if the test is not significant at certain level of significance x
Alternative hypothesis serves as the claim which requires statistical test on other to establish it's significance.
Answer:
f(-5) = 1/ 243
Step-by-step explanation:
f(x) = 3^x
Let x=-5
f(-5) = 3^-5
Since the exponent is negative, it will move to the denominator
f(-5) = 1/3^5
f(-5) = 1/ 243
Standard form: 8f + g + 18
