Let x be the angle
Complement of x is (90 degrees-x)
Supplement of x is (180 degrees-x)

4•(90-x)= 2/3(180-x)
3•4(90-x)=2(180-x)
1080-12x=360-2x
1080-360=12x-2x
720=10x
720/10= x
So x = 72 degrees

Please help me find the value of this expression 2[5(11 - 2)] - 16
german
Hello there, and thank you for asking your question here on brainly.

Short answer: 74

Why?

We have two sets of parenthesis here, and we have to do the parenthesis inside of the other parenthesis, (called brackets) first. (11 - 2 = 9) Now multiply 9 by 5. (9 × 5 = 45) Multiply 45 by 2 . . . (45 × 2 = 90) Finally, subtract 90 by 16. (90 - 16 = 74)

Hope this helped you! ♥

The mean waiting time at the drive-through of a fast food from the time the order is placed to the time the order is recieved is
Alexxandr [17]

Answer:

1.) No ;

2.) - 0.931

3.) 0.1785

Step-by-step explanation:

Given :

μ = 84.3 ; xbar = 81.9 ; s = 17.3

H0 : μ = 84.3

H1 : μ < 84.3

The test statistic :

(xbar - μ) ÷ (s/√(n))

(81.9 - 84.3) / (17.3/√45)

-2.4 / 2.5789317

= - 0.9306

= - 0.931

Using the test statistic, we could obtain the Pvalue : df = n - 1 ; df = 45 - 1 = 44

Using the Pvalue calculator :

Pvalue(-0.9306, 44) = 0.1785

Using α = 0.05

The Pvalue > α

Then we fail to reject H0; and conclude that there is no significant evidence to support the claim that the mean waiting time is less than 84.3
