what is the cubed roof of 16? Help needed please

Answer:

[tex]x<5[/tex]

Step-by-step explanation:

So we have the inequality:

[tex]3x-1<2x+4[/tex]

First, let's subtract 2x from both sides. The right cancels:

[tex]x-1<4[/tex]

Add 1 to both sides:

[tex]x<5[/tex]

And we're done!

Our solution is all number less than 5.

Answer:

(3^2) - n

Step-by-step explanation:

For this problem we will take it step by step to build the expression:

raise 3 to the 2nd power

= 3^2

then find the difference of the result and n

= (3^2) - n

Hence, your final expression should be (3^2) - n.

Step-by-step explanation:

The 6.25 divided by 132 equals 0.235 (rounded to three decimal places).

To calculate 6.25 divided by 132, perform the following steps:

Step 1: Divide the whole number part.

Divide 6 by 132, which equals 0 with a remainder of 6.

Step 2: Convert the remainder to a fraction.

The remainder 6 becomes 6/132.

Step 3: Divide the fractional part.

Divide 25 by 132, which gives the fraction 25/132.

Step 4: Add the results from Step 2 and Step 3.

Combine the fractions obtained in Step 2 and Step 3: 6/132 + 25/132 = 31/132.

The final result is 0 31/132, which can be simplified to 0 7/44 or written as a decimal as approximately 0.235. Therefore, 6.25 divided by 132 equals 0.235 (rounded to three decimal places).

Answer:

720

Step-by-step explanation:

6!/(6-6)! = 6!/0! or 6!/1

6! =720

The sum of the following figures = 800

To round up each decimal to the nearest hundred,

428.1 = 400

186.5 = 200

210.62 = 200

Answer:

We conclude that the proportion has increased owing to decreased parking spaces in the downtown district.

Step-by-step explanation:

We are given that the department of transportation in a particular city knows from past records that 27% of workers in the downtown district use the subway system each day to commute to and from work.

A random sample of 130 workers in the downtown district showed that 49 used the subway daily.

Let p = population proportion of workers in the downtown district use the subway system each day to commute to and from work.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]p \leq[/tex] 27%    {means that the proportion has decreased or remain equal owing to decreased parking spaces in the downtown district}

Alternate Hypothesis, [tex]H_A[/tex] : p > 27%    {means that the proportion has increased owing to decreased parking spaces in the downtown district}

The test statistics that will be used here is One-sample z-test statistics for proportions;

                           T.S.  = [tex]\frac{\hat p-p}{\sqrt{\frac{p(1- p)}{n} } }[/tex]  ~  N(0,1)

where, [tex]\bar X[/tex] = sample proportion of workers who used the subway daily = [tex]\frac{49}{130}[/tex] = 0.38

n = sample of workers = 130

So, the test statistics =  [tex]\frac{0.38-0.27}{\sqrt{\frac{0.27(1-0.27)}{130} } }[/tex]

                                     =  2.825  

The value of z-test statistics is 2.825.

Now, at a 5% level of significance, the z table gives a critical value of 1.645 for the right-tailed test.

Since the value of our test statistics is more than the critical value of z as 2.825 > 1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the proportion has increased owing to decreased parking spaces in the downtown district.

Answer:

You have a 1/2 or 50% chance of rolling a 4 or an even number

Step-by-step explanation:

They're three even numbers on a die 2,4,6 and that's half of the total option.

The probability of rolling a 4 and an even number is 2/3.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Sample space for rolling dice.

= {1, 2, 3, 4, 5, 6}

There are 6 possible outcomes.

There are three even numbers.

The probability of rolling a 4 or an even number.

= 1/6 + 3/6

= 1/6 + 1/2

= (1 + 3)/6

= 4/6

= 2/3

Thus,

The probability of rolling a 4 and an even number is 2/3.

so your pay for filling those is ...

  $0.41 × 1075 = $440.75

You get an additional amount of pay for the cartons filled on Saturday:

  $0.21 × 90 = $18.90

So your pay for the week is ...

Answer:

People who buy the company's products or services (customers)

Step-by-step explanation:

Morning Temperature = 20 degrees, Afternoon Temperature = 40 degrees

Morning Temperature = 26 degrees, Afternoon Temperature = 52 degrees

To find:

The ratio of the afternoon to morning.

Solution:

Taking any one pair of morning and afternoon temperature, we can find the ratio.

Morning Temperature = 15 degrees

Afternoon Temperature = 30 degrees

[tex]\text{Ratio}=\dfrac{\text{Afternoon Temperature}}{\text{Morning Temperature}}[/tex]

[tex]\text{Ratio}=\dfrac{30}{15}[/tex]

1 ) No of total slips after addition = 11

8 slip with 3 on it

3 slips with 9  on it

expectation value = probability of 3 x 3 + probability of 9 x 9

=  (8 / 11)  x 3 + (3 / 11)  x 9

24 / 11 + 27 / 11 = 4.636

2 )

No of total slips after addition = 12

8 slip with 3 on it

4 slips with 9  on it

expectation value = probability of 3 x 3 + probability of 9 x 9

=  (8 / 12)  x 3 + (4 / 12)  x 9

2 + 3 = 5

3 )

Let n be the required number

No of total slips after addition = 10+n

8 slip with 3 on it

2 + n  slips with 9  on it

expectation value = probability of 3 x 3 + probability of 9 x 9

=  (8 / 10+n )  x 3 + (2+n  / 10+n )  x 9 = 6

24 + 18 + 9n / 10 + n  = 6

42 + 9n = 60 + 6n

3 n = 18

n = 6

4 )

Let n be the required number

No of total slips after addition = 10+n

8 slip with 3 on it

2 + n  slips with 9  on it

expectation value = probability of 3 x 3 + probability of 9 x 9
