Answer: No

Step-by-step explanation:

Considering significant: p <= 0.05

A multiple choice question has 18 possible​ answers, only one of which is correct.

which means that the probability is 1 out 18, so

p = 1/18 = 0.056

As 0.056 > 0.050

Then, it is not significant

There are 200 carpenters in a crew. On a certain day, 150 were present. What percent showed up for work?
wariber [46]
The percentage would be 75% that carpenters that showed up for work
because when dividing 200 x 4 you will get 50 and 50 would equal to 25% of the total of carpenters and if you multiply 50 by 3 would get 150 and a percentage wise that would be 25% times three which is 75 and that’s how you get the answer

if the lesser of two consecutive even integers is seven more than half the greater, what are the two integers?
beks73 [17]

Answer: 16 and 18

Step-by-step explanation:

Let the lesser of two consecutive even integers is x.

Hence, the bigger of two consecutive even integers is (x+2).

\displaystyle\\x-\frac{x+2}{2}=7 \\

Multiply both parts of the equation by 2:

x(2)-(x+2)=7(2)\\2x-x-2=14\\x-2=14\\x-2+2=14+2\\x=16\\x+2=16+2\\x+2=18

WILL MARK! <br> For parallelogram ABCD, find x.
amid [387]

Answer:

x = 16

Step-by-step explanation:

If the figure is a parallelogram, the opposite sides are the same length

3x+20 = 5x-12

Subtract 3x from each side

3x+20 -3x = 5x-12-3x

20 = 2x-12

Add 12 to each side

20+12 = 2x-12+12

32 = 2x

Divide each side by 2

32/2 = 2x/2

16 =x
