Answer:

A, D

Step-by-step explanation:

for this table:

x 0 5 10 15 20 25 30 35 40

f(x) 5 6 7 8 9 10 11 12 13

A, assuming it's supposed to say f(5)=6, is true since 5 in x corresponds to 6 in f(x)

B is false, since the domain would be the set of all numbers in x, since domain corresponds to input (x) and range corresponds to output (f(x))

C is false, the range is not all real numbers since it is a defined set of numbers

D is true, since 15 in x corresponds to 8 in f(x)

Therefore, A and D are true

The ratio of Mike buying fish to Millie buying fish was 8 to 2. If in total they bought 150 pounds of fish. How many pounds did

Lady bird [3.3K]

Answer: Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.

Step-by-step explanation:

If the ratio is 8 to 2 then 8/10 will be the probability of Mike buying fist and 2/10 will be the probability of Millie buying fish.

Now multiply each fraction by the total number of pounds to find how many pounds each bought.

8/10 * 150 = 1200/10 = 120

2/10 * 150 = 300/10 = 30

In this case, Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.

What is the slope of the graph of 14x + 7y = –9? A. 1/2 B. -1/2 C. 2 D. -2

Debora [2.8K]

First move the 14x over to get 7y=-14x-9 then divide by 7 and you get y= -2x-9/7. the slope is the value next to the x in y=mx+b form so the slope is -2

All the fourth-graders in a certain elementary school took a standardized test. A total of 81% of the students were found to be

Answer:

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

Step-by-step explanation:

Let's define the events:

L: The student is proficient in reading

M: The student is proficient in math

The probabilities are given by:

$P (L) = 0.81\\P (M) = 0.74\\P (L\bigcap M) = 0.64$

$P (M\bigcap L^c) = P (M) - P (M\bigcap L) = 0.74 - 0.64 = 0.1\\P (M^c\bigcap L) = P (L) - P (M\bigcap L) = 0.81 - 0.64 = 0.17$

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17
