The probability that a randomly chosen participant in the survey will have visited both England and France is 0.5

Given data

number of clients = 70

travelled to England , France or both = 60

travelled to England = 45

travelled to France = 50

let:

E represent the client that visited England only,

F represent the number of client that visited France only,

EF represent the number of clients that visited both England and France only

we have

E + F + EF = 60

45 - EF + 50  - EF + EF = 60

45 + 50 - EF = 60

95 - EF = 60

95 - 60 = EF

EF = 35

E = 10

F = 15

probability

Pr = required outcome / possible outcome

= EF / clients surveyed

= 35 / 70

= 0.5

Explanation

EF represents the number of clients that visited England and France only, and it was solved to be 35. probability is the ratio of required outcome which 35 to the possible outcome which is the total number of clients 70. The ratio gives 0.5

Answer:

b = - 12

Step-by-step explanation:

substituting m = [tex]\frac{4}{5}[/tex] , x = 10, y = - 4 into y = mx + b , gives

- 4 = ([tex]\frac{4}{5}[/tex] × 10) + b

- 4 = (4 × 2) + b

- 4 = 8 + b ( subtract 8 from both sides )

The value of 165 pounds is 74.8 kilograms

The given parameter is:

1 kilogram = 2.205 pounds

Multiply both sides by 165

So, we have

165 * 1 kilogram = 2.205 pounds * 165

Divide both sides by 2.205

So, we have

165/2.205 * 1 kilogram = 2.205 pounds * 165/2.205

Evaluate the products

So, we have

74.8 kilogram = 165 pounds

Rewrite as

165 pounds = 74.8 kilogram

Hence, the value of 165 pounds is 74.8 kilograms

There are no real solutions for the equation x² + 20 = 4.

Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.

Consider the equation,

x² + 20 = 4

Subtracting 20 from each side of the equation.

x² + 20 - 20 = 4 - 20

x² = - 16

√x² = √ - 16

x = ± √-16

x = ± 4√(-1)

x = ± 4i

Since i is the complex number that is equal to √-1. Therefore, there are no real solutions to the equation.

Answer:no real number solutions

By using properties of right triangles, we will see that the value of x is 7.72

In the image we have a set of right triangles, and we want to find the value of x.

Let's look at the large triangle in the left, we know that the hypotenuse measures 18 units and one angle measures 64°, with that information we can get the adjacent side (the dashed line, let's call it A) to that angle:

Cos(64°) = A/18

18*cos(64°) = A = 7.05

Now we know one of the cathetus of the smaller right triangle (the one we can see in the right side). Here we know one angle that measures 20° and the opposite to that angle measures 7.05

Then the value of x is given by the equation:

x = 7.05/sin(20°) = 7.72

We conclude that the value of x is 7.72

The area of the shaded region in the first quadrant is: 0.75 units

The area under a curve between two points can be found by doing a definite integral between the two points.

Now,

Given:

To find: area bounded by the given lines and curve in the first quadrant.

Finding:

Now, according to the question, the lines x = 0 and y = 2 intersect at the point (0,2).

Point of Intersection of y = 2 and y = 3x - x²:

2 = 3x - x²

=> x² - 3x + 2 = 0

=> (x - 2)(x - 1) = 0

That is, the line and the curve intersect at two points: ( 1 , 2) and (2,2). But the point that is of our importance is only (1,2).

Thus, area shaded = [tex]\int\limits^1_0 {2 - 3x +x^{2}} \, dx[/tex] = 0.75 square units.

Step-by-step explanation:

According to the given statement One and half hour after the summer thunderstorm began, the temperature was approximately 1.0°F flower than at the start of the storm.

Subtract the final temperature from the starting temperature to get the temperature change (T). Multiply the temperature change by the sample's mass. Share the product's energy and heat output.

The equation is C = Q / (T m).

Consider the function t as defined below. t(h)=9.5h – 15.52 +17.4h-10.12

Here,

h is the number of hours after storm began.

The function t represents the rate of change of temperature in °F per hour during the hour and a half after the storm began.

During the storm, the temperatures lowers and then rises.

One and half hour after the summer thunderstorm began, the temperature was approximately 1.0°F flower than at the start of the storm.

As per the question:

No. of pea cans in a case = 18 cans

Weight of each can of peas = 12 ounces

Price of a case of peas = $14.22

The information regarding the weight of each can is redundant in this question and therefore, is not used for solving the question

Therefore, the formula to be used for solving:

Price per unit can of peas= (Price of a case of peas/No of pea cans in a case)

Price per unit can of peas= ($14.22/18)

The price per unit can of peas= $0.79
