X = 2.5
y = 2

Explanation:

3(9^x) = 27^y
3(3^2x) = 3^3y
3^(2x + 1) = 3^3y
2x + 1 = 3y
2x - 3y = -1, first equation

log2 y = 2 + log2 (x - 2)
log2 y = log2 (2^2) + log2 (x - 2)
log2 y = log2 (2^2 x [x - 2])
log2 y = log2 (4x - 8)
y = 4x - 8
8 = 4x - y
4x - y = 8, second equation

Multiply the second equation by 3
12x - 3y = 24, third equation

Subtract the first equation from the third, cancelling the positive and negative 3y
It results in:
2x - 12x = - 1 - 24
-10x = -25
x = 2.5

Substituting x = 2.5 in equation (1)
2(2.5) - 3y = -1
5 - 3y = -1
-3y = -6
y = 2

d1i1m1o1n [39]

Answer: option D

Step-by-step explanation:

The formulae for standard error = standard deviation/√n

But population standard deviation = 1.8 and sample size = n = 81

Standard error = 1.8/√81 = 1.8/9 = 0.2

A school has 1200 students 1/3 are in the upper school. 2/5 in the middle school and the remainder in lower school. How many stu
seraphim [82]

Answer:

257 students in the lower school

Step-by-step explanation:

you want to make the fractions have an equal denominator so make 1/3 5/15s and 2/5 to 6/15's, 5+6= 11/15s that leaves 4/15's for the lower part of the school

4 divided by 15 is 4.6 repeating so divide 1200 by 4.66 and boom

PLEASE HELP ME! A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = -10x + 3000.
tatuchka [14]
A) Plot a point at (0, 3000), then subtract 10 for every second that passes by.
B) The slope is negative because the skydiver is falling and the graph is plotting his descent, his x intercept is at (300, 0) which means he will touch land after 300 seconds
To find the the x intercept, make y equal 0 so 0=-10x+3000, subtract by 3000 on each side, and you end up with -3000=-10x, you then divide both sides by -10 and you end up 300=x or x=300
