Answer:

ratio=\frac{4}{7}

Step-by-step explanation:

Let

x ----> the number of coney dogs remained

y ----> the number of hot dogs remained

we have

x=4,y=7

we know that

To find our the ratio of coney dogs to hot dogs, divide the number of coney dogs by the number of hot dogs

so

ratio=\frac{x}{y}

substitute the given values

ratio=\frac{4}{7}

You are rolling a pair of dice what's is the probability of getting different numbers on both dice
padilas [110]

Answer:

Pr = 0.833

Step-by-step explanation:

Given

A roll of a pair of dice

Required

The probability of getting different numbers

First, list out the sample space;

We have:

S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6),

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

 (5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)\}

The total is:

Total = 36

The outcomes of the different numbers are:

Different = \{(1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 3) (2, 4) (2, 5) (2, 6),

(3, 1) (3, 2)(3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) \}

The total is:

Different = 30

So, the probability of having a different outcome is:

Pr = \frac{Different}{Total}

Pr = \frac{30}{36}

Pr = 0.833

The scores on a math test are normally distributed with a mean of 64 and a standard deviation of 8. Tara scored 52 on the test.
Dvinal [7]
A z-score<span> is the number of standard deviations from the mean a data point is.
</span>
Standard deviation explains by how much the members of a group differ from the mean value for the group.
Using the z-score formula:
                                           z = ( x  - μ ) ÷ σ
Where;
            x = score
            μ = Mean
            σ = Standard deviation 

Z- Score (Tara) = ( 52 - 64 ) ÷ 8
                         = - 12 ÷ 8
                         = - 1.5 

Z- Score (Jamal)  = ( 82 - 64 ) ÷ 8
                             = 18 ÷ 8
                             = 2.25 

Z- Score (Samuel) = ( 66 - 64 ) ÷ 8
                               = 2 ÷ 8
                               = 0.25
