Answer:

1) 5

2) 7

3) Mary

Step-by-step explanation:

1) 20/4 = 5 shots

20 shots = 4 minutes

10 shots = 2 minutes

5 shots = 1 minute

2) 42/6 = 7 shots

42 shots = 6 minutes

21 shots = 3 minutes

21 shots divided by 3 minutes equals 7 shots

3) Mary had 7 shots while John only shot 5.

Answer:

0.9803 = 98.03% probability that not more than 650 parents will attend the graduation ceremony.

Step-by-step explanation:

To solve this question, we need to know the Poisson and the normal distribution.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval. The standard deviation is the square root of the mean.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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.

The Poisson distribution can be approximated to the normal with same means, and [tex]\sigma = \sqrt{\mu}[/tex]

1/3 of the graduating seniors at a certain college have two parents attend the graduation ceremony, another third of these seniors have one parent attend the ceremony, and the remaining third of these seniors have no parents attend.

There are 600 graduating seniors. This means that the expected number of parents attending the ceremony is given by:

[tex]\mu = 600*(2*\frac{1}{3} + 1*\frac{1}{3} + 0*\frac{1}{3}) = 600(\frac{2}{3} + \frac{1}{3}) = 600(1) = 600[/tex]

And

[tex]\sigma = \sqrt{600}[/tex]

What is the probability that not more than 650 parents will attend the graduation ceremony?

Using continuity correction, as Poisson is a discrete distribution while the normal is continuous, this is [tex]P(X \leq 650 + 0.5) = P(X \leq 650.5)[/tex], which is the pvalue of Z when [tex]X = 650.5[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{650.5 - 600}{\sqrt{600}}[/tex]

[tex]Z = 2.06[/tex]

[tex]Z = 2.06[/tex] has a pvalue of 0.9803.

0.9803 = 98.03% probability that not more than 650 parents will attend the graduation ceremony.

Answer:

there answer is either a or c

Equation C represents circle A.Option C is correct.

It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.

The generalized equation of the circle with the coordinate(h,k) and radius r is;

(x-h)²+ (y-k) =r²

After graphing each and every equation given in the options we will come to the conclusion that equation c satisfies the given circle as;

(x-4)²+ (y-(-5)) =6²

(x-4)²+ (y-(-5)) =36

Hence option C is correct.

Step-by-step explanation:

Try doubling each possible answer (largest isn't required):

36oz for 2.59 doubled is 72oz for 5.18.

12oz for 1.99 doubled is 24oz for 3.98.

The clear answer is 72oz for 5.18 instead of 48oz for 3.99.

The function f(t) = log(t – 1) + 2 is increasing and has a domain of (1, ∞) option (A) is correct.

It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b = c\\log_ac =b[/tex]

The question is incomplete.

The complete question is:

Which function is increasing and has a domain of (1, ∞);

As we know, the function can be defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Graph the function f(t) = log(t – 1) + 2 on a coordinate plane.

As we can see in the graph, the graph of a function has a domain:

(0 , ∞)

And the function is increasing.

Thus, the function f(t) = log(t – 1) + 2 is increasing and has a domain of (1, ∞) option (A) is correct.
