Conditional Statement

Step-by-step explanation:

Here in this question, we are interested in selecting which of the options given has the same truth value as the contrapositive. The correct answer here is the conditional statement.

Logically, a contrapositive statement has the same truth value as a conditional statement. What this means is that they are logically equivalent.

A conditional statement is however not logically equivalent to its converse and inverse.

Moving digits around to a different place when counting up or down past 9 is called regrouping, borrowing, or trading.

There are several terms for moving digits around, some of them are:

All the above mean the same thing, and they perform the same purpose.

For instance:

Counting from 19 to 20 involves borrowing/carrying/trading/regrouping of 1

Hence, the correct option is (d) all of the above

Answer:

sin(x) = 2/√13

Step-by-step explanation:

In the first quadrant , all the trig identity (sin, cos and tan) are all positive.

Given tan(x) = 2/3

According to TOA, tan(x) = opposite/adjacent = 2/3

opposite = 2

adjacent = 3

Using pythagoras theorem to get the hypotenuse;

Hyp² = opp²+adj²

Hyp² = 2²+3²

Hyp² = 4+9

Hyp² = 13

Hyp = √13

According to SOH, sin(x) = opp/hyp

sin(x) = 2/√13

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

Answer:

$250

Step-by-step explanation:

We can make a pretty simple equation to help us solve this. If the tiller costs $59 for each day and she uses it for 5 days, the first step of our equation would be (59 x 5). Then she buys a rake for 3 dollars, that is adding to the equation

(59 x 5) + 3

Fist solve what is inside the parentheses. 59 x 5 = 250

250 + 3 = 250

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

Answer:

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

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:

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:

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 |

Answer:

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
