Answer:
a 36
b 3 blueberry, 2 bran
The least number of each type of muffin that Grant can make is 36. This would entail creating three batches of the blueberry recipe and two batches of the bran recipe. If Grant makes a 't' type of each muffin, where 't' equals 36, he would need three batches of blueberry muffins and two bran muffins.
In this question, Grant is trying to find the least common multiple (LCM) of the two muffin recipes. The LCM of a set of numbers is the smallest positive integer, a multiple of each number in the set. In this case, the blueberry muffin recipe makes 12 muffins, and the bran muffin recipe makes 18. The LCM of 12 and 18 is 36.
Therefore, the smallest number of each type of muffin Grant can make is 36. To achieve this, Grant will need to make three batches of the blueberry muffin recipe (because 3 * 12 = 36) and two batches of the bran muffin recipe (because 2 * 18 = 36).
So, if he makes 't' number of each type of muffin possible, that means 't' = 36, he would make 't/12' = three batches of blueberry muffins and 't/18' = 2 batches of bran muffins.

b. Keep the base the same and then add the exponents.
c. Multiply the bases and then subtract the exponents.
d. Keep the base the same and then subtract the exponents.
Answer:
The correct option is d. To simplify the given expression we should keep the base the same and then subtract the exponents.
Step-by-step explanation:
The given expression is
In the above expression we have common base 3 but the exponents are different.
According to the rule of exponent, if the numerator and denominator have same base and different exponent, then the base remains the same and the exponent of denominator subtracted from exponent of numerator.
Use this rule in the given expression.
Therefore the correct option is d.
Answer:
d or Keep the base the same and then subtract the exponents.

Answer:
15.74% of the player's serves were between 115 mph and 145 mph
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What percentage of the player's serves were between 115 mph and 145 mph
This is the pvalue of Z when X = 145 subtracted by the pvalue of Z when X = 115.
X = 145
has a pvalue of 0.9987
X = 115
has a pvalue of 0.8413
0.9987 - 0.8413 = 0.1574
15.74% of the player's serves were between 115 mph and 145 mph
A total of 27% of the player's serves at the U.S. Open Tennis Championship were between 115mph and 145mph. This was found using the Empirical Rule which applies to a normal distribution of serve speeds.
This problem is a classic example of the use of the Empirical Rule in statistics. The Empirical Rule, also known as the 68-95-99.7 rule, applies to a normal distribution, which is a bell-shaped curve (mound-shaped and symmetric) as mentioned in the problem. This rule states that approximately 68% of the data falls within one standard deviation from the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Given that the mean serve speed is 100 mph and the standard deviation is 15 mph, serves of 115 mph are one standard deviation above the mean and serves of 145 mph are three standard deviations above the mean. Therefore, we are looking for the percentage of serves between these two values. According to the Empirical Rule, this would be 95% (coverage for up to 2 standard deviations) minus 68% (coverage for up to 1 standard deviation), which equals 27%. So, 27% of the player's serves were between 115 mph and 145 mph.

Answer: 22.265
Step-by-step explanation: 4.201x5.3 = 22.265
The charity needs to earn 55,000 dollars. Subtracting the donation of 10,000 they need to make 45,000 dollars from the race entries. They make 40 dollars per entry, so dividing 45,000 by 40 gives the number of race entries needed: 1125.
The charity makes $40 per race entry ($55 entry fee minus the $15 cost). It also receives an additional $10,000 in donations. To raise at least $55,000, the charity would need to make at least $45,000 from race entries because $55,000 - $10,000 = $45,000. This is the target earnings from the race entries.
The race entry is $40 so we divide the target by the amount earned per race to find out the number of race entries needed: $45,000 / $40 = 1125. Therefore, the charity would need to have at least 1125 race entries to raise at least $55,000.
So the inequality would be: 40x + 10,000 ≥ 55,000, where x is the number of race entries. Solving the inequality would give x ≥ 1125.

Step-by-step explanation:
$55,000 - $10,000 = $45,000
$55 - $15 = $40
$45,000 : $40 = 1,125 race entries needed
