The probability of getting an even number or a 1 is 11/20

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Given that there are 20 cards numbers 1,2... 20.

A card is randomly drawn.

We have to find the probability of drawing either 1 or even card.

P(drawing even card) = no of even cards/total cards = 10/20= 0.5

P(drawing one) = no of 1's/total cards = 1/20 = 0.05

P(drawing both one and even card) = 0 (since impossible)

Hence P(drawing even or one) =0.5+0.05-0

=0.55

= 11/20

The distances travelled in each hour for both part are given as 5760 m and 5.76 km respectively.

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given problem can be solved by ratio method as follows,

(A)  The average walking rate is 1.6 m/s

The speed in meter per hour is calculated as,

1 second = 1/3600 hour

Take the ratio of 1.6 and 1/3600 as follows,

1.6 ÷ 1/3600

= 3600 × 1.6

= 5760

(B) The average walking rate is 1.6 m/s

It implies that 1.6 m in 1 second.

Now, 1 m = 1/1000 km

=> 1.6 m = 1.6/1000 km

And, 1 second = 1/3600 hour

Thus, the distance travelled in kilometer per hour can be evaluated by taking the ratio as follows,

1.6/1000 ÷  1/3600

= (3600 × 1.6)/1000

= 5.76

Hence, the distances travelled per hour in meter and kilometer are given as 5760 m and 5.76 km respectively.

The percentage of data within 1 population standard deviation of the mean, to the nearest percent is; 71%

The mean of a data sample is defined as the average of that data sample. The formula for the mean is;

μ= ∑x/n

Thus;

μ = (58 + 58 + 50 + 64 + 59 + 62 + 58)/7

μ = 409/7

μ =  58.429

The standard deviation is defined as a measure of how dispersed the data is in relation to the mean. It is gotten from the formula;

σ = √[Σ(xi - μ)²/N]

Solving this with a standard deviation calculator gives;

σ = 4.065

Thus, 1 standard deviation from the mean is;

58.429 ± 1(4.065)

= (54.364, 62.494)

The values that fall in this range from the given data set are;

58, 58, 59, 62, 58

They are 5 in number out of 7 and so the percentage = (5/7) * 100%

a.) Constant Rate of Change - yes

b.) origin - yes

c.) Change in y / Change in x - yes

d.) rise/run - yes

e.) inverse - Not apply

What is the difference between rate of change and slope coefficient?

The terms rate of change, gradient, slope coefficient, and rise over run are all equivalent to the slope in a proportional relationship. The slope of a line describes the rate at which a variable changes in relation to another variable. Rate of change is the same concept, but it is more general and can be applied to any relationship, not just linear. Gradient is another term for the slope of a line, which is the change in one variable compared to the change in another variable. Slope coefficient is a mathematical term for the slope of a line, which is the ratio of the vertical change to the horizontal change. Rise over run is another term for the slope of a line, which describes the rate of change by measuring the vertical change (rise) over the horizontal change (run). All of these terms describe the same concept, which is the rate of change in a proportional relationship.

The value of cos60° is 1/2.

It is a triangle with constant angles of 30, 60, and 90. This triangle is always a right triangle, as one of the angles is 90 degrees. Thus, a right-angled triangle is formed by these angles. Additionally, the right angle is equal to the sum of two acute angles, which will have a 1: 2 or 2: 1 ratio.

We know,

For a 30-60-90 triangle, the sides opposite to 30° is a, the side opposite to 60° is √3a and the side opposite to 90° is 2a.

Therefore,

If a = 1,
