A data set includes the following grades: 98, 94, 93, 82, 61, 80. Suppose that 61 is removed from the data. How is the median af
puteri [66]

Answer:

<u>If we remove 61 from the data set, the median changes from 87.5 to 93.</u>

Step-by-step explanation:

1. Let's calculate the median of the original data set:

Median = (3rd term + 4th term)/2 because the number of terms are even and our median mark is the average of the two middle marks, in this case, 82 and 93.

Median = (82 + 93)/2

Median = 87.5

2. Let's calculate the median of the data set removing 61:

Median = 3rd term because our median mark is the middle mark, in this case, 93. It is the middle mark because there are 2 scores before it (80 and 82) and 2 scores (94 and 98) after it.

Median = 93

AveGali [126]

Answer:

f(x) = x

Step-by-step explanation:

note : slope is positive 1, so the x term must be positive

also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .

if we substitute this into the general equation for a line

y = mx + b, where m = +1 and b = 0,

we get y = x

or f(x) = x (in function form)

Troy is going to spain and needs to convert his dollars to euros. He knows that when he goes, $5.00 is equivalent to about 3.45
blsea [12.9K]

As the question says that Tory knows for $5 he will get 3.45 euros.

Now for the euro trip he needs to know the rate of conversion or the rate of euros per dollar.

To find the rate of conversion we need to use unitary method.

As we know that at the given rate he gets,

3.45 euros for $5

or the other way around

\$5=3.45 euros

Now, using the unitary method we get,

\$1=\frac{3.45}{5} =\0.69 euro

Therefore, at the given rate we can see that for each dollar Tory would get 0.69 euro.

The population of a town can be represented by the formula P(t) = 67.35 -
Vera_Pavlovna [14]

Answer:

B. -⅜ and 67.35

Step-by-step explanation:

An equation can be given in the slope-intercept form such as y = mx + b, where,

m is the slope and b is a constant which is the y-intercept.

In the case of the formula, P(t) = 67.35 - 3t/8,

The constant, 67.35, in the equation, is the y-intercept (b)

The number multiplying the variable, t, which is -⅜, is the slope (m) of the equation.

Slope = -⅜, y-intercept = 67.35
