No, Emma will not have enough money left over to spend 3 times as many catnip toys as chew toys.

For planning our spending, saving, and investing, we need math. In each scenario, having a solid grasp of mathematical ideas will be advantageous to your own finances. We are all effectively "bankers" in our individual lives because the term "banking" relates to handling money.

In this question,

1. Emma needs to spend $35 on 2 chew toys and 1 bag of dog food, which comes out to $20 + $15.

2. She has $65 in leftover funds because she has $100 to spend and $35 to spend it on.

3. She would need to spend $30 on 6 catnip toys, which is three times the amount she would spend on chew toys.

4. Nevertheless, she has just $65 left over, which is insufficient to pay for six catnip toys.

5. Consequently, Emma does not have enough cash on hand to purchase three times as many catnip toys as chew toys.

Answer:

The annual rate of interest would have to be approximately 12.77% for Terrance to earn $600 in interest in 4.7 years from an investment of $12,000.

Step-by-step explanation: This can be calculated by using the formula:

(future value) = (principal) * (1 + (interest rate) )^(number of years)

where future value = $12,600, principal = $12,000, number of years = 4.7

so (12600/12000)^(1/4.7) = 1 + r

r = (12600/12000)^(1/4.7) - 1 ≈ 12.77%

The range of the number of letters in the sampled last names is 7.

The range of a set of data is the difference between the largest and smallest values. In this case, the data is a set of numbers representing the number of letters in the sampled last names. To find the range, we need to first find the largest and smallest numbers in the set.

From the data, we can see that:

The largest number is 12

The smallest number is 5

Thus, the range of the number of letters in the sampled last names is:

12 - 5 = 7

B) The apothem of a regular pentagon is 4.6797 cm, and the perimeter is 34 cm. The area equals 79.55

And

C) The apothem of a regular octagon is 6.0355 cm, and the length of a side is 5 cm. The area equals 120.71

Step-by-step explanation:

The apothem of a regular pentagon is 4.6797 cm, and the perimeter is 34 cm. The area equals 79.55 and The apothem of a regular octagon is 6.0355 cm, and the length of a side is 5 cm. The area equals 120.71

Polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.

The formula for the area of a regular polygon is A=1/2aP

Where a is the length of the apothem and P is the perimeter.

The apothem of a regular pentagon is 4.6797 cm, and the perimeter is 34 cm. The area equals 79.55

A=1/2×4.6797×34

We have to get 79.55 to tell the option B is true.

A=79.55

SO option B is correct.

Now let us check for C.

The apothem of a regular octagon is 6.0355 cm, and the length of a side is 5 cm. The area equals 120.71

Perimeter of octagon =8a

a is the side

Perimeter=8×5=40

A=1/2×6.0355×40

A=120.71 square centimeter.

Hence, option B and option C are correct.

The histogram of Petal. Length shows that the data is distributed in a slightly skewed unimodal shape, with most of the data concentrated in the lower range of petal length values. This indicates that the majority of observations have petal lengths of less than 4.0 cm. The bin-width used was 0.5 and the data was distributed into 9 bins.

The boxplot of Petal. Length reveals more information about the distribution of the data. The median value is 3.0, the interquartile range is from 2.0 - 5.1, and there are some outliers with values greater than 6.0. This indicates that while the majority of observations have petal lengths between 2.0 and 5.1 cm, there are a few observations with petal lengths greater than 6.0 cm. This boxplot also shows that the data is slightly skewed to the right, as the median is less than the mean, which is 3.76 cm.

The numeric value of the function H(x) = 10 + 0.07x when x = 20 is given as follows:

11.4.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function in this problem is defined as follows:

H(x) = 10 + 0.07x.

When x = 20, the numeric value is found replacing the lone instance of x by 20, hence:

H(20) = 10 + 0.07(20)

H(20) = 10 + 1.4

H(20) = 1.4.

The probability that the sample proportion of males will be at least 0.30 is 0.1043.

It can be calculated by using a binomial probability formula. The formula is P(X ≥ 30) = ΣP(X = k), where k = 30, 31, 32, . . . , 200.

The probability is 0.1043.

b. After adding the male host, the station records select a random sample of 200 callers and finds that 30% are male. This provides convincing evidence to suggest that the proportion of male callers has increased from 20%. This is because the probability of observing a sample proportion of 30% or higher is 0.1043, which is greater than the 0.05 significance level commonly used in hypothesis testing. This means that the probability of the observed sample proportion being due to chance is very low and it is likely that the proportion of male callers has increased.
