<h2><u>Corect option</u> :</h2>

= \color{plum}\tt(C) 7 \frac{2}{4}

<h2><u>Answer with steps</u> :</h2>

Quantity of water she needs = \tt \frac{3}{4} \:  cup

Number of servings she needs = 10

Number of cups of water she will need :

= \tt \frac{3}{4} \:   \times 10

=  \tt\frac{30}{4}

=\tt  7\frac{2}{4} \:  cups

Thus, she needs \tt  7\frac{2}{4} \:  cups of water.

Therefore, the correct option is \color{plum}\tt(C) 7 \frac{2}{4}

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airp
Nitella [24]

Answer:

The 95% confidence interval estimate of the population mean rating for Miami is (5.7, 7.0).

Step-by-step explanation:

The (1 - α)% confidence interval for the population mean, when the population standard deviation is not provided is:

CI=\bar x\pm  t_{\alpha/2, (n-1)}\cdot\ \frac{s}{\sqrt{n}}

The sample selected is of size, n = 50.

The critical value of t for 95% confidence level and (n - 1) = 49 degrees of freedom is:

t_{\alpha/2, (n-1)}=t_{0.05/2, 49}=2.000

*Use a t-table.

Compute the sample mean and sample standard deviation as follows:

\bar x=\frac{1}{n}\sum {x}=\frac{1}{50}\times [6+4+6+...+9+6]=6.34\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{50-1}\times 229.22}=2.163

Compute the 95% confidence interval estimate of the population mean rating for Miami as follows:

CI=\bar x\pm  t_{\alpha/2, (n-1)}\cdot\ \frac{s}{\sqrt{n}}

     =6.34\pm 2.00\times\frac{2.163}{\sqrt{50}}\\\\=6.34\pm 0.612\\\\=(5.728, 6.952)\\\\\approx(5.7, 7.0)

Thus, the 95% confidence interval estimate of the population mean rating for Miami is (5.7, 7.0).

In the United States, there are 59 different species of mammals that are endangered,
jolli1 [7]

Given Information:

Number of endangered mammal species = 59

Number of endangered bird species = 75

Number of endangered fish species = 68

Required Information:

Probability of either a  mammal or a fish = ?

Answer:

P(mammal or fish) = 127/202 = 0.6287 = 62.87%

Step-by-step explanation:

We want to randomly select one animal and find out the probability of either a mammal or a fish.

The total number of endangered species of animals is given by

Total animals = mammal species + bird species + fish species

Total animals = 59 + 75 + 68  = 202

The probability of selecting a endangered mammal is

P(mammal) = no. of endangered mammal/total no. of endangered animals

P(mammal) = 59/202

The probability of selecting a endangered fish is

P(fish) = no. of endangered fish/total no. of endangered animals

P(fish) = 68/202

Finally, the probability of selecting either a mammal or a fish is

P(mammal or fish) = 59/202 + 68/202

P(mammal or fish) = 127/202

P(mammal or fish) = 0.6287

P(mammal or fish) = 62.87%
