The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?

Answers

Answer:

1/6 of a chance aka 16.666?%

Step-by-step explanation:

The probability of drawing a card with number 7 is 0.166.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

From the given set of cards,

Total number of cards =6

Number of spades = 3

Number of card with number 7 on it = 1

Probability of drawing a 7 = 1/6

= 0.166

Therefore, the probability of drawing a card with number 7 is 0.166.

Step-by-step explanation:

Multiply 3 by each number in the parentheses and keep the variable

Using the distribution property 3(5p + 1) is 15p + 3.

What are the basic properties of arithmetic laws of operations?

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

what is the midpoint of 23.8 and 23.7?

Answers

Answer:

23.75

Step-by-step explanation:

Answer:

23.75

Step-by-step explanation:

1. 23.8 - 23.7 = 0.1

2. 0.1 ÷ 2 = 0.05

3. 0.05 + 23.7 = 23.75

this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)

1)What if you have two equations equal to y? How do you solve for x?
2)If you need to solve for a variable to substitute, what is your first step?
3)What does it mean to substitute for a value?

Answers

Answer:

Step-by-step explanation:

If you have two equations for y, eliminate y by setting these two equations equal to one another. Solve the resulting equation for x. Then substitute your x value into one of the equations for y. Write your solution as (x, y).

2) If you need to solve for a variable to substitute, what is your first step? Example: If you have two equations for y, eliminate y by setting the two equations equal to each other. This decides for you that you must solve for x.

3) What does it mean to substitute for a value? Example: If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x. This eliminates y and allows you to solve for x.

2. 200.52 4. 212.67 5. 148.48

Step-by-step explanation:

for (2) you find the area of each shape first the square

12*12=144

then you find the area of the semicircle

the formula is A= (3.14)r^2/2

the (r) is 6 because that is half of the whole side of the semicircle

so... (3.14) 6^2/2

6*6= 36

(3.14)36/2

113.04/2

56.52

then add the 144 from the square to it

56.52+144

200.52

-85.5 (area of the triangle)

-127.17 (area of the semicircle)

Task:
Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?

Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.

Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft

Answers

Answer:

318 days or 10.6 months,

No, because the time between august and december is 8 months and it would take 10 to complete the tunnel

Step-by-step explanation:

start by determining the slope:

subtract the remaining distance from the total distance to determine distance so far, then divide by time.

m = (3200 - 1700)/5

m = 1500/5

m = 300

y = mx + b

Plug in to solve for x.

3200 = 300x + 0

3200 = 300x

divide y by m. This is x. (this is known as inverse operation if you didnt know already.)

3200 = 300(10.6_)
