Answer:

339 $\frac{2}{3}$

Step-by-step explanation:

We will use PEMDAS to solve

-><em> I am going to assume you did not mean to have the problem twice as the last part is the same, just formatted differently, but if I am incorrect please let me know</em>

[Given] 14(38−14)+33÷9

[Subtract] 14(24) + 33 ÷ 9

[Multiply and divide] 336 + 3 $\frac{2}{3}$

[Add] 339 $\frac{2}{3}$

Have a nice day! - Note: I found another problem very similar to this where people were saying it is 9 and that this answer is incorrect, but I am not sure how they found it. Just wanted to let you know.

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

★ Also please leave the rating you think I deserve (It helps other users learn as well as helps me improve my answers)

Answer:

a) there are 2520 possible groups of engineers

b) the probability is 0.76 (76%)

c) the probability is 1/19 ( 5.26%)

Step-by-step explanation:

a) the possible combinations when there is grouping of elements is

C= n!/(a!*b!. ...) , where n= total size and a,b,... = are the group sizes of a ,b and others

in our case , for 8 elements in 4 groups of 2 is

C = 8!/(2!*2!*2!*2!) = 8!/2⁴ = 2520 possible groups of engineers

b) defining the event W= the cellphone works after a week , then the probability is

P(W) = probability that the cellphone is flawed * probability that the cellphone works after a week given that the cellphone is flawed + probability that the cellphone is not flawed * probability that the cellphone works after a week given that the cellphone is not flawed = 0.2 * 0.2 + 0.8 * 0.9 = 0.76

c) the conditional probability can be calculated with the theorem of Bayes. Defining the event F= the design is flawed. Then we have

P(F/W)= P(F∩W)/P(W) = 0.2 * 0.2/0.76 = 1/19 ( 5.26%)

where

P(F∩W) = probability that the design is flawed and the cellphone works after a week

P(F/W)= probability that the design is flawed given the cellphone was still working after a week

How many revolutions will a car wheel of 30in make as the car travels 1 mile? (1 mile = 5280ft)?

Nataliya [291]

30inc=76.2cm
76.2*pi=76.2pi
1cm=0.0328084 foot
1 mile=<span>5280 ft
</span>5280/0.0328084=160934.4
1 mile=160934.4 cm
160934.4 /76.2pi=672.27
672 revolutions i think

Help on this plzzz real quick

BlackZzzverrR [31]

8 and 15 are the lengths of the legs.
The tangent is the ratio of the lengths of legs.
In general, tan x = opp/adj
You have 8/15, so here 8 is the opposite leg and 15 is the adjacent leg.
Angle A is the right angle, so that is not it.
For which acute angle, B or C, is 8 opposite and 15 adjacent?
Answer: for angle B.
Therefore, 8/15 must be tan B.
