Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

Answers

Answer 1

Answer:
Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !

To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:

√ ( 225 + 64 ) .

Jeremy is 5 years younger than his older sister. His older sister is 9 years older than his younger sister. The total of their age is 49. Write and solve an equation to find the ages of Jeremy and his sisters. I need help please!

Answers

Jeremy=x
Older sister=x+5
younger sister=x+5-9 or x-4
x+(x+5)+(x-4)=49
combine like terms
3x+5-4=49
3x+1=49
subtract 1 from both sides
3x=48
divide both sides by 3
x=16
Jeremy=16
Older sister=16+5=21
younger sister =16-4 or 16+5-9=12
J=16
OS=21
YS=12

Jeremy - x
Older sister - x+5
Younger sister - x-4
3x+1=49
3x=48
X= 16

Jeremy: 16
Older sister: 21
Younger sister: 12

which situation would be represented by a discrete probability distribution? a) the weight of fire fighters b) the overall average of a math class c) the ages of all the students in a class d) the number of students who could distinguish between two different soft drinks

Answers

A discrete variable is a variable which may take only certain discrete values; for example the number of people in a household is a discrete variable which may have the value 1, 2, 3, etc. but cannot have intermediate values such as 1.473 or 3.732.
Choice d) can be represented by a discrete probability distribution, the other choices cannot be so represented.

Cara has $25 to buy dry pet food and treats for the animal shelter. A pound of dog food cost $2 and treats are $1 apiece. If she buys 9 pounds of food, what is the greatest number of treats she can buy?

Answers

If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.

For the function y = x + 4, what is the output value if 3 is the input value?y = 1
y = 7
y = 12
y = 34

Answers

y = 7 is the output value for the given function y = x+4.

What is a function?

It is an expression, rule, or law that defines a relationship between one independent variable and dependent variable.

Given function is

y = x+4

where y is the output value and x is the input value of the given function.

If x= 3 then y is given by

y = 3+4 = 7

Hence, for the given function y = x+4 the value of y is 7 when x is 3.
