Answer:

The answer to number 2 is 1

Step-by-step explanation:

\frac{1}{5}  \times 5 =  \frac{1}{5} \times  \frac{5}{1}  \\  \\  \frac{5 \times 1}{5 \times 1 }  =  \frac{5}{5}  =  \frac{1}{1}  = 1

Answer: The answer to Number 4 is 1!

Step-by-step explanation:

First you solve for the numbers in parentheses. 16 - 7 is 9, and 2 x 4 is 8. Then you solve for the remaining numbers. So 9 - 8 is indeed 1.

Hope this helps! :)

At the beginning of spring, Taylor planted a small sunflower in her backyard. When it was first planted, the sunflower was 25 in
BlackZzzverrR [31]

Answer:

Step-by-step explanation:

The sunflower then began to grow at a rate of 2 inches per week. This means that the rate of growth of the sunflower is in arithmetic progression. We would apply the formula for determining the nth term of an arithmetic sequence which is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 25 inches

d = 2 inches

To determine the height after 7 weeks, T7

n = 7

T7 = 25 + 2(7 - 1)

T7 = 25 + 12

T7 = 37 inches

To determine the height after w weeks, Tw

n = w

Tw = 25 + 2(w - 1)

Tw = 25 + 2w - 2

Tw = 23 + 2w

In parts ​(a) through ​(e)​ below, mark the given statement as True or False. Justify each answer. All vectors are in set of rea
Oxana [17]

Answer:

(c)

"The given statement is true, by definition of length of a vector v, ||v|| = \sqrt{v\bullet v}"

Step-by-step explanation:

(a) v  \bullet v = || v ||^2

That is completely correct Remember that if  v = (x_1,x_2,x_3)\\ then

v \bullet v = x_1*x_1+x_2*x_2+x_3*x_3 = x_1^2+x_2^2+x_3^2 = ||v||^2

Therefore the correct answer would be (c).

"The given statement is true, by definition of length of a vector v, ||v|| = \sqrt{v\bullet v}"

Ages of sylvans daughters are consecutive even integers. The sum of their ages is 60. Write an equation representing and find ag
notka56 [123]
Consecutive even integers are 2 apart
they are
x,x+2,x+4
total sum is 60
x+x+2+x+4=60
3x+6=60
minus 6 both sides
3x=54
divide both sides by 3
x=18
x+2=20
x+4=22

the ages are
18,20,22

Fynjy0 [20]

Answer: (23.3,\ 29.7)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm ME., where \overline{x} is the sample mean and ME is the margin of error .

Given : The sample mean : \overline{x}=26.5

Margin of error : ME=3.2

Then , the range of values​ (confidence interval) likely to contain the true value of the population parameter will be :-

26.5\pm 3.2=(26.5-3.2,\ 26.5+3.2)=(23.3,\ 29.7)

Hence, the range of values​ likely to contain the true value of the population parameter =  (23.3,\ 29.7)
