Damien is competing in both swimming and running at a competition. After analyzing himself and his competitors, he knows that he has a 65% chance of winning at swimming and an 85% chance of winning at running. What is the probability that he will win the running event, but lose the swimming event?
Answer:
[tex]Probability = 0.2975[/tex]
Step-by-step explanation:
Giving:
Swimming
[tex]P(Win[Swim])= 65\%[/tex]
Running
[tex]P(Win[Run])= 85\%[/tex]
Required
Determine the probability of winning at running and losing at swimming
First, we calculate the probability of losing at swimming using
[tex]P(Win) + P(Lose) = 1[/tex]
Substitute 65% for P(Win)
[tex]65\% + P(Lose[Swim]) = 1[/tex]
Collect Like Terms
[tex]P(Lose[Swim]) = 1 - 65\%[/tex]
[tex]P(Lose[Swim]) = 35\%[/tex]
The required probability is then calculated using:
[tex]Probability = P(Win[Run]) * P(Lose[Swim])[/tex]
[tex]Probability = 85\% * 35\%[/tex]
Convert to decimal
[tex]Probability = 0.85 * 0.35[/tex]
[tex]Probability = 0.2975[/tex]
how do you solve this
21 = 14 + 7x
Answer:
subtract 14 from each side
7=7x
x=1
Step-by-step explanation:
plz brainliest!
The required solution to the equation 21 = 14 + 7x is x = 1.
An equation is a mathematical statement that shows the equality between two expressions. It consists of an equal sign (=) separating the two sides of the equation.
To solve for x, we can first subtract 14 from both sides of the equation:
21 - 14 = 14 + 7x - 14
Simplifying:
7 = 7x
Next, divide both sides of the equation by 7:
7/7 = 7x/7
1 = x
Therefore, the solution to the equation 21 = 14 + 7x is x = 1.

Hailstones form when strong winds support ice particles high in clouds. We can assume that the diameter of a hailstone varies directly with the time the hailstone takes to form. A hailstone with a diameter of 0.75 inches takes about 12 minutes to form. Write an equation that gives the hailstone’s diameter d after t minutes. Then find the diameter of a hailstone that takes 20 minutes to form.
Answer:
the equation y= ax represents direct variation between x and y is said to vary directly with x. the nonzero constant a is called the constant of variation.

The plastic cylinder has a diameter of 2 cm. There is a rectangular 0.6 cm square prism through the middle of the cylinder, extending from the top to the bottom. The height of the cylinder is 6 cm. Find the volume of the cylinder without the prism.
Answer:
16.69 cm³
Step-by-step explanation:
In finding the volume of the cylinder without the prism you find the volume of the cylinder assuming it has no prism in it then minus the volume of the prism
Volume of the cylinder assuming there is no prism through it
V=πr²h where r is radius of the cylinder and h is height of the cylinder
Given that diameter = 2, then r= 1 cm and height, h = 6cm
V= π * 1 * 1 * 6
V= 18.85 cm³
Volume of the rectangular prism
V= l*w*h
V= 6*0.6*0.6
V= 2.16 cm³
The volume of the cylinder without the prism
18.85 cm³-2.16 cm³ = 16.69 cm³

Answer:
0.333n + 28 ; 33.3 ; $41.653
Step-by-step explanation:
For the best fit line :
The slope of the graph :
Drawing a right angled triangle at any point on the best fit line :
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (45 - 30) / (50 - 5)
Gradient = 15 / 45
Gradient = 0.333
Intercept :
Where best fit line crosses the y - axis = 28
b = 0.333n + 28
The extra cost of each extra call made made is the slope of the graph :
$0.333 = 33.3 cents
Estimated cost of 41 calls
b = 0.333(41) + 28
b = $41.653
Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.
A circle has an arc whose measure is 80° and whose length is 88. What is the diameter of the circle?
Answer:
length of arc=80/360×2πr
88×360=80×2×22/7×r
31680×7/(80×2×22)=r
r=221760/3520=63

Alvin is 15 younger than elga the sum of their age is 27 what is elga age
Answer:
27 years old
Step-by-step explanation:
Let Alvin's age be x and Elga's age is y:
y - x = 15
x + y = 27
2y = 42 (use elimination method)
y = 21
x = 6 (plug it back into either equation)
Therefore Alvin is 6 and Elga is 27

A holiday costs £1900. Work out the price after a 9% discount
Hey there!
The answer to your question is £1729.
To solve this equation, first we find how much is left. 100% - 9% = 91 %. That means that the new price is 91% of the old price. So, we can do 0.91 x 1900, and we get 1729.
Therefore, the new price is £1729.
Hope it helps! Have a great day, and good luck!

1. Find the slope and y-intercept of the graph of the following equation.
y=-x+4
Answer:
Slope -1 , y intersept is (0,4)
Answer:
Y intercept=4 and the slope is -1/1 or -1
Step-by-step explanation:
The numeral by itself is the Y intercept and thw number next to the x would be the slope is there is no number its just one and if its a single number for ex 4x it would be 4/1 so your answer would be Y intercept=4 and the slope is -1/1 or -1
