First we need to calculate 25% of 120. If 120=100% and X=25% then 120•25=100•X
3000=100X
X=30. Now we know that 25% of 120 is 30.
Now we need to calculate 40% of 120. If 120=100% and y=40%, then 120•40=100y
4800=100y
y=48. Now we know that 40% of 120 is 48.
To find out how many more questions had Riley finished then Annabel, we need to subtract 48 with 30
48-30=18
FINAL ANSWER—18

Hope this helped❤️

What is the measurement of ∠BAC and ∠ABC? Explain your process of solving.
Paraphin [41]

Answer:

<BAC = 78

<ABC = 68

Step-by-step explanation:

The remote angles theorem states that when one extends a side of a triangle, the angle formed between the extension and one of the sides of the triangle is equal to the sum of the two non-adjacent angles inside the triangle. One can apply this theorem here and state the following,

<BAC + <ABC = <ACD

Substitute,

(5y + 3) + (4y + 8) = (146)

Simplify,

9y + 11 = 146

Inverse operations,

9y + 11 = 146

     -11     -11

9y = 135

/9      /9

y = 15

Now substitute this value back into the expressions to find the numerical measurement of (<BAC) and (<ABC),

<BAC = 5y + 3

5(15) + 3

78

<ABC = 4y + 8

4(15) + 8

68

The dot plot below shows the number of cakes 31 chefs made in a week: Dot plot labeled Number of Cakes Made shows 4 dots over 1,
Paraphin [41]
The median, because the data is not symmetric and there are outliers is the data is not symmetric and there are outliers.

The median of the data set is 8 cakes, while the average is 7.5.

However, 21 of the 31 chefs, or roughly 2/3, made 8 or more cakes. This makes the median a better center for this data, since the data is clearly skewed. The four chefs that made 1 cake each brings the average down, skewing the mean and making the median a better representation of the data.

Step-by-step explanation:

The asymptote of the graph y = 1 (Horizontal asymptote)

As you can see a line that a graph is approạching to as it heads towards infinity but it does not intersect.

Moreover, the value of y is decreasing over its domain. as you can see in the graph.
