Answer:

Men can be concluded to enjoy shopping electronic activity more than women, but in weekend days. The case might not hold true for week working days also.

Step-by-step explanation:

To study :  whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy that.

  • Out of 67 men, 24 said they enjoyed the activity

So, % of men enjoying the activity  = (24 / 67) x 100

= 35.82%

Out of 24 women, 8 said that they enjoyed the activity

So, % of women enjoying the activity = (8 / 24) x 100

= 33.33%

professor190 [17]

Answer: 6

Step-by-step explanation:

Given the following expression:

8a-1+0.5b

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

a=\frac{1}{4}\\\\b=10

Then;

 8a-1+0.5b=8(\frac{1}{4})-1+0.5(10)

Now you must solve the multiplications:

=\frac{8}{4}-1+5=2-1+5

The final step is to add the numbers. Therefore, you get the following answer:

=6

laiz [17]

Answer:

h^{*} = 25\,in

Step-by-step explanation:

Let consider that door has a height of 5 feet and a width of 3 feet. The scale factor is:

n = \frac{15\,in}{3\,ft}

n = 5\,\frac{in}{ft}

The height of the cabinet is:

h^{*} = n \cdot h_{door}

h_{*} = \left(5\,\frac{in}{ft}  \right)\cdot (5\,ft)

h^{*} = 25\,in

jek_recluse [69]

Answer:

0.278

Step-by-step explanation:

Given that Nuri joins a game for a car. The rule is that Nuri pick one key from box either A, B, or C. A box has two keys but only one can be used. B box has three keys but only one can be used. C box has two keys but none of them can be used.

Each box is equally likely to be selected.

In other words

P(A) = P(B) = P(C)=\frac{1}{3}

If A is selected then probability of winning is using the correct key out of two keys i.e. 0.5

If B is selected then probability of winning is using the correct key out of three keys i.e. 0.333

If c is selected then probability of winning is using the correct key out of two keys i.e. 0.00

So the probability that Nuri can win the car

= \frac{1}{3} *0.5+\frac{1}{3} *0.333+\frac{1}{3} *0\\= 0.278
