Answer:
5.6
Step-by-step explanation:
Given :
Quality rating for 8 movies :
5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2
Let rating for the 9th movie = x
Average quality rating olfor the 9 movies = 6.4
To find x :
Sum of all ratings / number of ratings = 6.4
(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4
(52 + x) / 9 = 6.4
52 + x = 57.6
x = 57.6 - 52
x = 5.6

Explanation:
Since [tex] \overline{PR} [/tex] is a diameter, arc [tex] \stackrel{\Large\frown}{PQR}\:= 180°. [/tex]
Given that [tex] \angle{SUR} = 42°[/tex] is a subtended central angle by two diameters,
[tex] \stackrel{\large\frown}{RS} \:= 42° [/tex].
Using the rule of arcs, [tex] \stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS} [/tex] →
[tex] 180° + \: 42° = \: \stackrel{\Large\frown}{PQS} [/tex]
[tex] 222° = \: \stackrel{\Large\frown}{PQS} [/tex]

the fastest 3 runners in a race qualify for the next event. how many different groups of Runners could advance to the next event from a race that has seven runners
Answer:
35 different groups of 3 runners can be selected
Step-by-step explanation:
Here, we want to simply calculate the number of 3 runners that can advance in a race from a total of 7
What we want to do here is to simply get different groups of 3
So, we have it that we simply want to know the number of different ways we can select 3 from a total of 7
We can simply use combination for this;
We have the general combinatorial as;
nCr = n!/(n-r)!r!
With respect to this particular question, n = 7 and r = 3
So we have;
7C3 = 7!(7-3)!3! = 7!/(4)!3! = 35
An airplane is 16,000 feet above the ground. It begins to descend at a rate of 140 feet per minute. Write an equation you could use to solve for x, the number of minutes it will take until the plane is 12,600 feet above the ground.
Answer:
16000=140x
It will take 90 minutes to hit 12,600 ft above ground.
Step-by-step explanation:
Just swap out 16000 for 12600. Then solve from there.

Answer:
square root of 34
Step-by-step explanation:
You're the magnitude or the norm of the vector AB so you will square the X and Y components and then add them and put them in a square root
so
5 squared is 25
(-3) squared is 9
25+9 is 34
so the answer is the square root of 34

1/2x + 3/5 as the product of a constant and sum of terms
Answer:
Step-by-step explanation:
Do you mean that you want to create a distributive statement with 1/2 on the outside and a sum of 2 terms on the inside of a set of brackets? That's pretty wordy, but I mean something like
1/2 (x + a)
1/2*a = 3/5 Multiply both sides by 2.
a = 2 * 3/5
a = 6/5
Answer
1/2 ( x + 6/5)

what is the slope of 10x-2y=8?
Answer:
Slope: 5
Step-by-step explanation:
Mark as brainllest
Answer:
x= 1 /5 y+ 4 /5
Step-by-step explanation:
Let's solve for x.
10x−2y=8
Step 1: Add 2y to both sides.
10x−2y+2y=8+2y
10x=2y+8
Step 2: Divide both sides by 10.
10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5

Answer:
The hundredths place is where its at
Answer:
Hundredths place.
Step-by-step explanation:
Hi so their race times are the same up to that fourth number.
In a number with a decimal anything after the dot goes: tenths, hundredths, thousandths and so on.
In both number we just go two more places so it would be hundredths.

Jack paid $4:00 for 6 pounds of apples. What is the ratio of the price of apples to the pounds of apples?
Answer:
you get 1.5 pounds of apples per dollar (1 pound and 8 ounces)
Step-by-step explanation:
6 and 4 will not work so we need to use decimals
since we have a gap of two, we need to be able to use it four times
2=0.5
1.5 x 4 = 6
or we could just divide it... never mind forget it
your answer is 1.5 pounds of apples per dollar
Answer:
The ratio of the price of apples to the pound of apples: 2:3
Step-by-step explanation:
4:6

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% rate each day. Part 1: Is this a growth or decay problem? ( 1 point) Part 2: Which equation correctly represents this problem (2 points) A) y=146(24)x B) y=146(1.024)x C) y= 146(1.24)x
Answer:
(a) Growth
[tex](b)\ y = 146(1.24)^x[/tex]
Step-by-step explanation:
Given
[tex]a= 146[/tex] -- current
[tex]r = 24\%[/tex] --- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
Hence, it is a growth problem
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:
[tex]y = a(1 + r)^x[/tex]
Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]
[tex]y = 146 * (1 + 24\%)^x[/tex]
[tex]y = 146 * (1 + 0.24)^x[/tex]
[tex]y = 146 * (1.24)^x[/tex]
[tex]y = 146(1.24)^x[/tex]
