Step-by-step explanation:

Answer:

90 = | x - 122 |

Step-by-step explanation:

Given;

maximum temperature, 212 °F

minimum temperature, 32 °F

First, determine the difference of both values;

212 - 32 = 180

Divide this value by 2

180/2 = 90

90 = | x - 212 + 90|

90 = | x - 122 |

where;

x is the temperature of water

Thus, the absolute value equation that represents the minimum and maximum temperature of liquid water is 90 = | x - 122 |

Test statistic    |Z| = |-2.21|

calculated value Z = 2.21 > 1.96 at 0.05 level of significance

Null hypothesis is rejected

The researchers state that, in the U.S., today’s undergraduates not study an average of 14 hours per week

Step-by-step explanation:

Step(i):-

Given Mean of the Population' μ' = 14 hours per week

Given random sample size 'n'= 35

Mean of the sample (x⁻) = 16.7 hours per week

standard deviation of the Population (σ) = 7.2 hours per week

Level of significance = 0.05

Step(ii):-

Null hypotheses :H₁: µ = 14

Alternative Hypothesis : H₂: µ ≠ 14

Test statistic

              [tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]

              [tex]Z = \frac{14-16.7}{\frac{7.2}{\sqrt{35} } }[/tex]

               Z = -2.21

            |Z| = |-2.21|

The tabulated value

                    Z₀.₀₅ = 1.96

calculated value Z = 2.21 > 1.96 at 0.05 level of significance

 Null hypothesis is rejected

The researchers state that, in the U.S., today’s undergraduates not study an average of 14 hours per week

Answer:

7

Step-by-step explanation:

A rectangle has a length that is 8 times the width

The area of the park is 392 square units

Let y represent the width of the park

Since the length is 8 times the width then, l= 8x

Therefore the width of the park can be calculated as follows

8x × x= 392

8x^2= 392

x^2= 392/8

x^2= 49

x= 7

Hence the width of the park is 7

Answer:

x=2

Step-by-step explanation:

0.95x +0.05(12-x) = 0.10(24)

Distribute

0.95x +0.6-0.5x= 2.4

add/subtract like terms

0.9x+0.6=2.4

subtract 0.6 from both sides

0.9x=1.8

Divide both sides by 9

0.1x=0.2

multiply both sides by 10

x=2

Subtract 5 from each side

t +5-5 = 9-5

t = 4

The temperature at 2:00 PM will be 73 degrees

What is temperature ?

Coldness and hotness is measured by temperature which is one of the fundamental units of measurements.

Here, it is given that the temperature at sunrise was 61 degrees and it is find the temperature at 2 P.M which as increase by 12 degrees. Now calculating it by adding 61 degree with 12 degrees :

the temperature at 2:00 PM = 61 degrees + 12 degrees = 73 degrees

Answer:

The answer is below

Step-by-step explanation:

Let the number of bottles be y and the number of minutes the machine operate be x.

Given that number of bottles be is proportional to the number of minutes the machine operate, hence:

y is proportional to x.

⇒ y α x

y = kx, where k is a constant

when the number of bottles (y) = 250, the time the machine operates (x) = 20 minute. Therefore:

y = kx

250 = 20k

k = 250/20

k = 12.5

Hence the relationship between x and y is given as:

y = 12.5x

Plotting the function y = 12.5x using geogebra

Answer:

a = 60

b = 90

c = 150

Step-by-step explanation:

Numerele a, b și c sunt direct proporționale cu 2, 3 și 5.

Unde k este constantă de proporționalitate

a ∝ 2

a = 2k

b ∝ 3

b = 3k

c ∝ 5

c = 5k

Dacă media aritmetică a celor trei numere este egală cu 100, determinați numerele a, b și c

= 2k + 3k + 5k / 3 = 100

= 10k / 3 = 100

Cross Multiply

= 10k = 3 × 100

= 10k = 300

Împărțiți ambele părți la 10

k = 300/10

k = 30

Pentru numărul a

a = 2k

a = 2 × 30

a = 60

Pentru numărul b

b = 3k

b = 3 × 30

b = 90

Pentru numărul c

c = 5k

c = 5 × 30

c = 150

Prin urmare, a = 60, b = 90, c = 150

I got the answer right on Edge

Step-by-step explanation:

if a person whose salary is Rs 18500 has to pay 13% tax pay 18500 into 13 by hundreds equals to 185 into 13

The amount of tax the person has to pay is Rupees  2405.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A person whose salary is Rupees 18500 has to pay 13% tax.

So, The amount of tax he has to pay is 13% of 18500.

∴ (13/100)×18500.

= 13×185.

= 2405 Rupees
