The angels in a triangle should be 180° all
85+64+30=179<180
so we should add 1° to the first one
the angels would be 86 64 30

The dot plots show 9 scores on a 10 question trivia game for two students. Select all the statements that must be true.

Burka [1]

Answer:

The correct statements are b, c and e.

Step-by-step explanation:

Consider the dot plot for Noah and Jada's score in the trivia game.

From the dot plot it is quite clear that the data form a bell-shaped curved or a normal curve.

For the normal distribution:

Mean = Median = Mode

Noah's mean score = 5

Jada's mean score = 3

The standard deviation of a data set is the measure of dispersion of the observations of that data set from their mean.

On closely studying the graphs we can see that the Noah and Jada's scores are almost at a same distance from the mean, i.e. the spread of Noah's score is same as the spread of Jada's score.

So, the correct statements are:

b. The standard deviation of Noah's scores is equal to the standard deviation of Jada's scores.

c. The mean of Noah's scores is greater than the mean of Jada's scores.

e. Using only Noah's scores, the mean is equal to the median

Answer:

$84\frac{5}{9}$ ↔ $45\frac{2}{9}+39\frac{3}{9}$

$6\frac{2}{9}$ ↔ $-24\frac{5}{9} + 30\frac{7}{9}$

$-23.24$ ↔ $28.98+(-52.22)$

$131.87$ ↔ $56.7+75.12$

Step-by-step explanation:

$84\frac{5}{9}$ and $45\frac{2}{9}+39\frac{3}{9}$

Convert $84\frac{5}{9}$ to an improper fraction.

To write 84 as a fraction with a common denominator, multiply by $\frac{9}{9}$

Combine the numerators over the common denominator.

$\frac{84*9+5}{9}$

$\frac{756+ 5}{9}$

$\frac{761}{9}$ = $45\frac{2}{9}+39\frac{3}{9}$

covert $45\frac{2}{9}$ to an improper fraction

Combine the numerators over the common denominator.

$\frac{761}{9}$ = $\frac{45*9+2}{9}$ + $39\frac{3}{9}$

$\frac{761}{9}$ = $\frac{407}{9}$ + $39\frac{3}{9}$

covert $39\frac{3}{9}$ to an improper fraction

Combine the numerators over the common denominator.

$\frac{761}{9}$ = $\frac{407}{9}$ + $\frac{39*9+3}{9}$

$\frac{761}{9}$ = $\frac{407}{9}$ + $\frac{354}{9}$ → $\frac{407+354}{9}$

$\frac{761}{9}$ = $\frac{761}{9}$

therefore the statement $84\frac{5}{9}$ = $45\frac{2}{9}+39\frac{3}{9}$ is true

$6\frac{2}{9}$ and $-24\frac{5}{9} + 30\frac{7}{9}$

Convert $6\frac{2}{9}$ to an improper fraction.

To write 6 as a fraction with a common denominator, multiply by $\frac{9}{9}$

$\frac{6*9}{9} +\frac{2}{9}$ → $\frac{54+2}{9}$ → $\frac{56}{9}$

Convert $-24\frac{5}{9}$ and $30\frac{7}{9}$ an improper fraction

$-24\frac{5}{9}$ → $-(\frac{24*9}{9} + \frac{5}{9} )$ → $-\frac{24*9+5}{9}$ → $-\frac{221}{9}$

$30\frac{7}{9}$ → $\frac{30*9}{9} +\frac{7}{9}$ → $\frac{30*9+7}{9}$ → $\frac{277}{9}$

$\frac{56}{9}$ = $-\frac{221}{9}$ + $\frac{277}{9}$ →

$\frac{56}{9}$ = $\frac{56}{9}$

therefore the statement $6\frac{2}{9}$ = $-24\frac{5}{9} + 30\frac{7}{9}$ is true

$28.98+(-52.22)$ and $-23.24$

$28.98 - 52.22$ → $-23.24$

$-23.24$ = $-23.24$

therefore the statement $28.98+(-52.22)$ = $-23.24$ is true

$131.87$ and $56.7+75.12$

$56.7+75.12$ → $131.872$

$131.87$ ≠ $131.872$

therefore the statement $131.87$ = $56.7+75.12$ is False

Barrett works at an ice cream shop. The function f(x) represents the amount of money in dollars Barrett earns per gallon of ice

Paha777 [63]

Answer:

$f(g(x))=6x^3} +4$

Step-by-step explanation:

Given:

$f(x)=2x^2+4\\\\g(x)=\sqrt{3x^3}$

Required:

f(g(x))=?

Solution:

let f(g(x))=f(X), where X=g(x)

so $f(X)=2X^2+4$

put X= $g(x)=\sqrt{3x^3}$ , we get

$f(g(x))=2(\sqrt{3x^3} )^2+4$

$f(g(x))=2(\sqrt{3x^3} )^2+4\\\\f(g(x))=2({3x^3} )+4\\\\f(g(x))=6x^3} +4$
