Answer:
Step-by-step explanation:
1) i think for the first question any probability greater than 0.4 has more likelihood that it will happen
2) mutually exclusive events are ones that cannot occur at the same time as it's impossible e.g. a single coin toss cannot result in you getting heads and tails

Step-by-step explanation:
If construction costs are $160,000 per kilometer, find the cost of building the new road in the figure
shown to the right
new road
10,000 m
24,000 m
The cost of building the new road is s
(Round to the nearest dollar as needed)
Answer:
$4,160,000
Step-by-step explanation:
First, find the length of the new road in km using Pythagorean Theorem.
According to Pythagorean Theorem:
c² = a² + b²,
Where, c is the longest leg, which is the hypotenuse, a and b are the 2 other legs of the ∆.
Since we are calculating the lenght in km, convert each lenght of the two legs of the ∆ into km.
1 km = 1,000 m
10,000 m = 10 km
24,000 m = 24 km
c² = 24² + 10²
c² = 576 + 100
c² = 676
c = √676
c = 26 km
Lenght of the new road = 26 km
If cost of construction is $160,000 per kilometer, therefore, cost of constructing 26 km road = 160,000*26 = $4,160,000
The cost of building the new road is $4,160,000.
Calculation of the cost of building:here we determine the length by using the Pythagorean Theorem.
So,
[tex]c^2 = a^2 + b^2[/tex]
Here
c is the longest leg
And, a and b are the 2 other legs of the ∆.
Now
1 km = 1,000 m
10,000 m = 10 km
24,000 m = 24 km
So,
[tex]c^2 = 24^2 + 10^2[/tex]
c² = 576 + 100
c² = 676
c = √676
c = 26 km
Now the cost should be
= 160,000(26)
= $4,160,000

Answer:
7k
Step-by-step explanation:
−k−(−8k) = -k +8k = 7k
If k(x)=5x-6, which expression is equivalent to (k+k)(4)
Answer: (k+k)(4)=28
Step-by-step explanation:
(k+k) (4) means the same as adding k(4) and k(4). Since we are given k(x), we can use it to solve. There are two ways to solve. One is to find k(4), and then add them. Another way is to do (k+k)(x), then plug in x=4. I will show both methods.
Method 1
k(4)=5(4)-6 [multiply]
k(4)=20-6 [subtract]
k(4)=14
(k+k)(4)=14+14 [add k(4) and k(4)]
(k+k)(4)=28
--------------------------------------------------------------------------------------------------------
Method 2
(k+k)(x)=5x-6+5x-6 [combine like terms]
(k+k)(x)=10x-12
(k+k)(4)=10(4)-12 [plug in x=4, multiply]
(k+k)(4)=40-12 [subtract]
(k+k)(4)=28
--------------------------------------------------------------------------------------------------------
Now, we know that (k+k)(4)=28. We confirmed this with both methods.

I need some help: A survey of 120 persons was conducted at TCC, and it was found that 97 persons carried a cell phone, 12 persons carried a tablet computer, and 9 carried both a cell phone and a tablet. How many people carried a cell phone or a tablet?
Answer:
100
Step-by-step explanation:
n(u)=120 total people in survey
n(c)=97 people carrying cell phone
n(t)=12 people carrying tablet
n(c∩t)=9 people carrying both tablet and cell phone
n(c∪t)=? people carrying cell phone or tablet
now,
n(c∪t)= n(c)+n(t) - n(c∩t)
= 97+12-9
=109-9
=100
there fore the number of people carrying cell phone or tablet = 100

If DE = 5x, EF = x + 8, and DF = 20, what is EF? Simplify your answer and write it as a proper fraction, mixed number, or integer. Please if you could(or not) type the answer step by step.
Answer:
EF = 10
Step-by-step explanation:
DE + EF = DF
5x + x + 8 = 20
6x = 20 - 8
6x = 12
x = 12/6
x = 2
EF = x + 8 = 2 + 8 = 10

8. A pizza shop charges $7.00 for a cheese pizza and $1.50 per topping. The total charge for Megan's pizza was $11.50. Write and solve on equation to determine how many toppings Megan ordered on her pizza. Variable: Equation: Solution:
Answer:
Variable
x which stands for no. of toppings on pizza
equation
7 + 1.5x = 11.50
solution
the no. of toppings = 3
Step-by-step explanation:
Let the number of topping be x.
Cost of 1 topping = $1.50
Cost of x topping = x*Cost of 1 topping = $1.5*x = $1.5x
Cost of cheese pizza = $7.00
Total cost for cheese pizza for x topping = Cost of cheese pizza + Cost of x topping
Total cost for cheese pizza for x topping = 7 + 1.5x
Given that The total charge for Megan's pizza was $11.50
thus,
7 + 1.5x = 11.50
1.5x = 11.50 - 7
1.5x = 4.5
x = 4.5/1.5 = 3
Thus, there were three toppings
______________________________________
Variable
x which stands for no. of toppings on pizza
equation
7 + 1.5x = 11.50
solution
the no. of toppings = 3
3s – 12 = -21
Solve for s
Answer:
S= -3
Step-by-step explanation:
3s-12=-21
3s= -21+12
3s= -9
s= -9/3
s= -3
Answer:
s = -3
Step-by-step explanation:
[tex]3s - 12 = - 21[/tex]
Collect like terms
[tex]3s = - 21 + 12[/tex]
Add the numbers :
[tex] - 21 + 12 = - 9 \\ \\ 3s = - 9[/tex]
Divide both sides of the equation by 3
[tex] \frac{3s}{3} = \frac{ - 9}{3} [/tex]
Simplify
[tex]s = - 3[/tex]

please help me im confused
Answer:
it a d) option i.e d) AAS test
make me as brilliest and follow me....mUse the number line below, where , , and . a. What is the value of y? b. Find RS and ST. R S T a. What is the value of y? y 4 (Type an integer or a decimal.) b. Find RS and ST. RS 4.2 (Type an integer or a decimal.)
Answer:
y = 4
RS = 35
ST = 26
Step-by-step explanation:
Given:
RS = 8y + 3
ST = 5y + 6
RT = 61
Required:
a. Value of y
b. Numerical lenght of RS and ST
SOLUTION:
a. Points R, S and T are collinear, therefore, based on segment addition postulate, the following equation can be created to find the value of y:
[tex] RS + ST = RT [/tex]
[tex] (8y + 3) + (5y + 6) = 61 [/tex] (substitution)
Solve for y
[tex] 8y + 3 + 5y + 6 = 61 [/tex]
Combine like terms
[tex] 8y + 5y + 3 + 6 = 61 [/tex]
[tex] 13y + 9 = 61 [/tex]
Subtract 9 from both sides
[tex] 13y + 9 - 9 = 61 - 9 [/tex]
[tex] 13y = 52 [/tex]
Divide both sides by 13
[tex] \frac{13y}{13} = \frac{52}{13} [/tex]
[tex] y = 4 [/tex]
b. RS = 8y + 3
Plug in the value of y
RS = 8(4) + 3 = 32 + 3
RS = 35
ST = 5y + 6
Plug in the value of y
ST = 5(4) + 6 = 20 + 6
ST = 26

Help with writing the set from an interval notation.
Answer:
(-oo, 1) U (1, 3) U (3, oo)
Step-by-step explanation:
We have a line with two arrowheads. The arrow heads show us that the numbers in the set continue forever in the negative direction past -5 and in the positive direction past 5. In this case, the set consists of all real numbers except 1 and 3 since they have open circles.
That means the set is from negative infinity to 1, from 1 to 3, from 3 to positive infinity, but leaving out 1 and 3.
Remember that a regular parentheses symbols, ( and ), do not include the number near them and are used for open circles.
Square brackets, [ and ], do include the number near them and are used for closed circles.
Also, infinity and negative infinity are not numbers, so we always use regular parentheses when dealing with infinity or negative infinity.
We need the union of three sets:
from negative infinity to 1, from 1 to 3, from 3 to positive infinity
Answer: (-oo, 1) U (1, 3) U (3, oo)
