If length = a, width = b
if double both a and b will double its area?
area of a rectangle is ab
if double both a and b then the area is (2a)(2b) = 4ab (then peter is wrong because the area will be 4 times not double)

Assume the population has a distribution with a mean of 110 and a standard deviation of 8. For a random sample of size 40, find

VARVARA [1.3K]

Answer:

109.33

Step-by-step explanation:

given that the population has a distribution with a mean of 110 and a standard deviation of 8

Sample size n = 40

Std error of sample mean = std dev/square root of sample size

= $\frac{8}{\sqrt{40} } \\=1.265$

From std normal distribution table we find that 30th percentile for Z is

-0.5244

Corresponding x score = $110-0.5244*1.265=109.33663$

30th percentile = 109.33663

=109.33

Solve x − 5y = 6 for x.

pentagon [3]

Answer:

All real numbers

Step-by-step explanation:

Solve a system of equations by elimination

With the equation given, you can solve for y to get: y = $\frac{1}{5}$ x - $\frac{6}{5}$

Then, substitute this value in on the equation.

x - 5( $\frac{1}{5}$ x - $\frac{6}{5}$ ) = 6

x - x + 6 = 6

6 = 6

The solution is all real numbers

1.3 Find the next number in the sequence: -16; -9; -2: _ a. 12 6.7 C. 5 d.-5 1.4 3 = b.1 6.6 d. 27

iogann1982 [59]

Answer:

given sequence, -16; -9; -2: _

first term(a)=-16

common difference(d)=-9-(-16)=7

next term is 4

4th term=a+(n-1)d

=-16+(4-1)7=-16+21=5
