Mode = is the number with the highest frequency so the answer is 4.
Mean = the average so the answer is 3+4+5+4+6+4+7=33 so 33/7=4.7 (rounded to the nearest one decimal).
Median = the middle number, so the answer is 4.
Answer:
8
Step-by-step explanation:
y²+by+16= (y+4)²
y²+by+16= y²+2*4*y+4²
y²+by+16= y²+8y+16
by=8y
b=8
Answer:
32 people people came in blue cars.
6 people came in red cars.
Step-by-step explanation:
Here, the given total number of people in the group = 48
Number of people who came in blue cars = Two - thirds
Now, Two - thirds of 48 =
So, total 32 people out of total 48 people came in blue cars.
Number of people who came in red cars = One- eighth
Now, One- eighth of 48 =
So, total 6 people out of total 48 people came in red cars.
Answer:
a =4 and b= 3
Step-by-step explanation:
Stare at it for a bit. You have the squre of x, then(ignoring the minus sign) 2 times x times 4. What's left is the square of 4, which is 16; you have 13, you are 3 short. Let's add them to both sides:
so a =4 and b= 3
In an equation like that, y would double into 2y. But just keep in mind that what happens to one side must happen to another.
