Answer:
A picture is needed for me to solve
Step-by-step explanation:
median- 49
mean- 50
Steps: find median order the numbers from least to greats the number in the middle is your median if there are two numbers in the middle you add the two numbers then divide by 2
find mean add all the numbers then divide by how many numbers there in this case you divide by 7
Answer:
OB=4
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
4x+5−5=21−5
4x=16
Step 2: Divide both sides by 4.
4x/4=16/4
x=4
Answer:
x=4
A. A savings account’s balance.
Answer:
B. b = 3a + 2
Step-by-step explanation:
We can write the equation in slope-intercept form as b = ma + c, where,
m = slope/rate of change
c = y-intercept/initial value
✔️Find m using any two given pair of values, say (2, 8) and (4, 14):
Rate of change (m) = change in b/change in a
m = (14 - 8)/(4 - 2)
m = 6/2
m = 3
✔️Find c by substituting (a, b) = (2, 8) and m = 3 into b = ma + c. Thus:
8 = 3(2) + c
8 = 6 + c
8 - 6 = c
2 = c
c = 2
✔️Write the equation by substituting m = 3 and c = 2 into b = ma + c. Thus:
b = 3a + 2
