You are dealt one card from a standard 52-card deck. Find the probability of being dealt a 9 and an 8

Answers

The probability to being a 9 and an 8 from a standard 52 - card deck

will be;

⇒ 2 / 13

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

The total number of cards = 52

Number of a 9 dealt = 4

Number of a 8 dealt = 4

Now,

Total number of cards = 52

And, Number of dealt a 9 and an 8 card = 4 + 4

= 8

Since, Probability = Number of dealt a 9 or 8 / Total number of cards

Thus, The probability of being dealt a 9 and an 8 will be;

= 8 / 52

= 2 / 13

Therefore, The probability to being a 9 and an 8 from a standard 52 - card deck will be;

⇒ 2 / 13

A new road is being constructed parallelto the train tracks through point V. An equation of the line representing thetrain tracks is y = 2x.Find an equation of the linerepresenting the new road.

Answers

the equation of the line representing the new road will be 2 x - y + 7 = 0.

The line is:

y = 2 x.

The slope of the line is:

m = 2

Now, the point V is:

V = (- 2, 3)

Since the train track is parallel to the line, its slope will be:

m' = 2 ( slope of parallel lines are equal)

So, the equation of the new road line will be:

y - y₁ = m (x - x₁)

y - 3 = 2 ( x + 2)

y - 3 = 2 x + 4

2x - y + 7 = 0

Therefore, the equation of the line representing the new road will be 2 x - y + 7 = 0.

When comparing two items of the same kind, a ratio is utilized. For two numbers, a and b, the ratio formula is written as a: b or a/b. Two or more ratios are deemed to be in proportion if they are all equal.

A ratio is a divisional comparison of two quantities, and a proportion is the equality of two ratios.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other.

The equivalence of two ratios is referred to as proportion. There is never a difference between two comparable ratios. The ratio symbol (::) is used to express proportions, which aid in solving problems involving ambiguous quantities.

Three points determine △ABC. The distance between A and B is 16.2 feet. The distance between B and C is 12.9 feet. What is the range for the distance between A and C? The range of the distance from A to C is greater than___feet and less than___feet.

Answers

The range of the distance from A to C is greater than 3.3 feet and less than 29.1 feet.

How to determine the range of distance?

The given parameters are

AB = 16.2 feet

BC = 12.9 feet

To determine the range of the third length, we use the triangle inequality theorem

Using this theorem, we have the following inequalities

AB + BC > AC

AB + AC > BC

BC + AC > AB

So, we have

16.2 + 12.9 > AC

16.2 + AC > 12.9

12.9 + AC > 16.2

Solve for AC in the above inequalities

29.1 > AC

AC > -3.3

AC > 3.3

Remove the negative value

29.1 > AC

AC > 3.3

Rewrite as

AC > 29.1

AC > 3.3

This means that the values of AC are between 3.3 and 29.1 feet

percent error = | theoretical value - experimental value | / theoretical value × 100

Therefore,

percent error = |2.3 - 2.5| / 2.3 × 100

percent error = 0.3 / 2.3 × 100

You have the the length of segment NK is 23.

Furthermore, you have that segment NK is the sum of the following segments:

NK = NM + ML + LK

Each of the previous segments are given by the following algebraic expressions:

NM = x - 6

ML = 9

LK = 2x - 19

You sum the previous expression, by taking into account that the result is 23. Then you solve for x, just as follow:

NM + ML + LK = NK

(x - 6) + (9) + (2x - 19) = 23 eliminate parenthesis

x - 6 + 9 + 2x - 19 = 23 simplify similar terms

x + 2x - 6 - 19 + 9 = 23

3x - 16 = 23 add 16 both sides

3x = 23 + 16

3x = 39 divide by 3 both sides

x = 39/3

x = 13

Hence, the solution for x is x = 13

The data is misleading because the scatter plot starts at $532, so a small increase in profits looks very large.

The data is misleading because Guillermo should expect to make more profits than $500-$600 per month.

The data is misleading because the profits of a new company should not show a decrease between months 2

I make between $6,000 and $9,000 a month on the coffee van on average working 30 to 40 hours a week.

If p and q vary inversely and p is 19 when q is 16, determine q when p is equal to 8.

Answers

The value of q solving with variation method is 38

How to calculate the value of q ?

Variation van be described as the relationship between a set of variable. We will be applying inverse variation to solve the question

The value of q can be calculated by using variation method

p= k/q

The first step is to calculate the constant k

19= k/16

cross multiply both sides

k= 19 × 16

k= 304

Since the value of k is 304, then the value of q can be calculated as follows

p = k/q

8= 304/q

cross multiply both sides

8q= 304

q= 304/8

q= 38

Hence the value of q when the value of p is 8 is 38
