We the Probability of pulling either fork or spoon as 1.

We are given that:

We have a fork and a spoon in a bag.

Total number of items in a bag = 1 + 1 = 2

Now, we need to tell the probability of either pulling a fork or a spoon.

Now,

Probability of pulling a fork = 1 / 2 = 0.5

Probability of pulling a spoon = 1 / 2 = 0.5

So, the Probability of pulling either of them will be = 1 / 2 + 1 / 2 = 1

Therefore, we the Probability of pulling either fork or spoon as 1.

The value of the integer number is -1

The statement is given as:

The sum of an integer and 7 times the next consecutive odd integer is 6

Let the integer value be x

So, the next consecutive odd integer is x + 2

When represented as an equation, we have

x + 7(x + 2) = 6

Open the bracket

x + 7x + 14 = 6

Evaluate the like terms

8x = -8

Divide both sides by 8

x = -1

Hence, the value of the integer number is -1

Answer:

Step-by-step explanation:

The domain of g(x) is the set of all real numbers. Meaning that all the numbers between the min and max of g would be -7 ≤ x ≤ 7.

Answer:

D. F

Step-by-step explanation:

Both F and G are not on plane P

Using integrals, the desired probabilities and measures are given as follows:

a) P(X < 6) = 0.84375 = 84.375%.

b) P(X < 13) = 1 = 100%.

c) P(6 < X < 8) = 0.15625 = 15.625%.

d) P(X > 5) = 0.31641 = 31.641%.

e) x = 6.434.

The distribution is given as follows, simplifying the operations:

f(x) = 0.09375x - 0.01171875x², 0 ≤ x ≤ 8.

Hence the density function is:

[tex]\int_{a}^{b} f(x) dx[/tex]

[tex]\int_{a}^{b} (0.09375x - 0.01171875x^2) dx[/tex]

[tex]0.046875x^2 - 0.00390625x^3|_{x=a}^{x = b}[/tex]

Applying the Fundamental Theorem of Calculus:

P(a < X < b) = 0.046875b² - 0.00390625b³ - 0.046875a² + 0.00390625a³

Hence, for item a:

P(X < 6) = 0.046875(6)² - 0.00390625(6)³.

P(X < 6) = 0.84375 = 84.375%.

For item b, the entire distribution is below 13, hence:

P(X < 13) = 1 = 100%.

For item c:

P(6 < X < 8) = 0.046875(8)² - 0.00390625(8)³ - 0.046875(6)² + 0.00390625(6)³.

P(6 < X < 8) = 0.15625 = 15.625%.

For item d:

P(5 < X < 8) = 0.046875(8)² - 0.00390625(8)³ - 0.046875(5)² + 0.00390625(5)³.

P(X > 5) = 0.31641 = 31.641%.

For item e:

We have to find b when a = 0 and P(X < b) = 0.9, hence:

0.046875b² - 0.00390625b³ = 0.9.

Using a calculator, the solution in the range of the distribution is given by:

b = x = 6.434.

coordinates of the new station= (5,98/4)

When two lines intersect at a point then the angle between them can be expressed in terms of their slopes and is given by the following formula:

tan θ = |

|where

are the slopes of the line AB and CD respectively.

If

is positive then the angle between the lines is acute. If

is negative then the angle between the lines is obtuse.

Slope of Vertical Lines

Vertical lines have no slope, as they do not have any steepness. Or it can be said, we cannot define the steepness of vertical lines.

A vertical line will have no values for x-coordinates. So, as per the formula of slope of the line,

Slope, m = (y2 – y1)/(x2 – x1)

But for vertical lines, x2 = x1 = 0

Therefore,

m = (y2 – y1)/0 = undefined

In the same way, the slope of horizontal line is equal to 0, since the y-coordinates are zero.

m = 0/(x2 – x1) = 0 [for horizontal line]

Positive and Negative Slope

If the value of slope of a line is positive, it shows that line goes up as we move along or the rise over run is positive.

If the value of slope is negative, then the line goes done in the graph as we move along the x-axis.

Let R,Q,T be the points that divide the line into 3:4 equal parts

Let the Q = (x,y)

R(1, 2) and T(8, 23) ,

x = m1x1+m2x2/m1+m2

y = m1y1+m2y2/m1+m2

X= 3.1+4.8/7

x= 3+32/7

x=35/7

x=5

y=2.3+23.4/3+4

y= 6+92/4

y=98/4

y= 24.5

(x,y) = (5,98/4)

Yes; The construction demonstrates how to bisect an angle correctly using technology because Circles D & E have the same radius

How to properly bisect an angle?

In construction of angles and lines, bisection means dividing either a given angle or line segment into two equal parts. This means after the construction, the two parts must have equal measure.

The steps to bisect a line segment are as follows;

1. Draw the required length of the line segment AB.

2. With point A and radius of the compass greater than half of AB, describe arcs above and below the segment.

3. With the same radius as in step 2 and point B, describe two arcs above and below the segment. These would intersect that of step 2 at C and D.

4. Join the points of intersection of the arcs with a straight line CD.

Now, in this given question with the circle, we can see that line AG is the line that bisects the angle EAD.

Now, we see that circles C and D have the same radius and as such the construction demonstrated is correct for that very reason.

Answer: yes

Step-by-step explanation: the construction correctly shows how to bisect an angle using technology because circles D and E have the same radius. 

The domain of sec(3.14t/4) is all real numbers except 2+4n, where n is any integer and range of sec(3.14t/4) is [tex](\infty,-1] \cup [1,\infty)[/tex].

The Domain of a function f(x) is the set of all values for which the function is defined.

The Range of a function is the set of all values that f takes.

As, [tex]sec x=\frac{1}{cos x}[/tex] , so sec x is defined where [tex]cos x \neq 0[/tex].

It implies, sec(3.14t/4) is defined where [tex]cos(3.14t/4)\neq 0[/tex].

The cosine is 0 at [tex](2n+1)\frac{\pi }{2}[/tex] , where n is any integer.

Now, [tex]\frac{3.14t}{4} =\frac{(2n+1)\pi }{2}[/tex]

         [tex]\frac{\pi t}{4} =\frac{(2n+1)\pi }{2}[/tex]

       [tex]t=2(2n+1)\\t=2+4n[/tex]

Since, the range of cos x is [-1,1], so sec x will never be less than 1, but can grow infinitely large as cos x approaches 0.

Thus, The domain of sec(3.14t/4) is all real numbers except 2+4n, where n is any integer and range of sec(3.14t/4) is [tex](\infty,-1] \cup [1,\infty)[/tex].

Horse runs at the faster rate i.e. at the rate of 58 feet per seconds.

According to the given question.

A bear can run 400 feet in 8 seconds.

A horse can run 290 feet in 5 seconds.

As we know that, the measurement of the speed at which something happens is called rate.

Therefore, form distance rate formula (rate = distance/time)

The rate of the bear =  400/8 = 50 feet/sec

And the rate of the horse = 290/5 = 58 feet/sec

Therefore, horse can run faster than bear.

Hence, horse runs at the faster rate i.e. at the rate of 58 feet per seconds.

The piecewise function for the monthly charge W(x) for a customer who uses x hours of electricity is given by:

The graph of the function is given at the end of the answer.

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, we have that:

The monthly charge is calculated differently according to the number of kWh of electricity used, divided into two cases as follows:

For up to 300 hours, the base charge of $50 plus the hourly fee of $0.0650 is charged, hence:

W(x) = 50 + 0.0650x, 0 ≤ x ≤ 300.

For more than 300 hours, the customer is charge 50 + 300 x 0.0650 = $69.5, plus the hourly fee of $0.0850, hence:

W(x) = 69.5 + 0.0850x, x > 300.
