The pattern here is the number times 3 then plus 1
We can check this by plugging it in.
1×3=3
3+1=4
4 is the next number in our sequence so the pattern works.
We can continue to check this with the rest of our sequence.
4×3=12
12+1=13
13 is the next number in our sequence so the pattern works.
13×3=39
39+1=40
40 is the next number in our sequence so the pattern works.
40×3=120
120+1=121
121 is the next number in our sequence so the pattern works.
We can find the next numbed in the sequence by continuing the patter
121×3=363
363+1=364
So the next number in the sequence is 364
0.1y = 3x^2
divide each side by 0.1
y = 3x^2/0.1
factor the right side to get y = 30x^2
this can't be written in the form y = kx so y does not vary directly with x
so there is no constant of variation.
Answer: x = 10
Explanation:
Proof that triangle CAB ~ EAD
Angle CAB = Angle EAD (same angle)
Angle ABC = Angle ADE = 90 degree
Thus, Triangle ABC ~ EAD (AA)
And CB/ED = 8/16 = 1/2
Which mean CB = (1/2)ED
That mean AB/AD also equal 1/2
Where AB = 1/2(AD)
We get:
x = 1/2(10 + x)
x = 5 + (1/2)x
x - (1/2)x = 5
(1/2)x = 5
x = 10
Answer:
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
Step-by-step explanation:
The estimate of the true proportion of all students who own a Texas Instruments calculator is the number of students who own a Texas Instruments Calculator divided by the total number of students.
6 students own a Texas Instruments Calculator
20 total students
p = 6/20 = 0.3
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
