Step-by-step explanation:

20% of $5 = 0.20*5 = $1.00

Using the confidence interval concept, an interval between 10 and 14.8 is likely to contain the true mean number of books read in the previous year by the population.

It means that it is x% likely that the population parameter(mean/proportion/standard deviation) is between a and b, which are the bounds of the confidence interval.

The bounds of the confidence interval are given by the estimate plus/minus the margin of error.

For this problem, we have that:

Hence the bounds are given by:

Answer:

50%

Step-by-step explanation:

Given that:

P(late) = P(L) = 50% = 0.5

P(Eat) = P(E) =?

P(LnE) = 40% = 0.4

P(LuE) = 60% = 0.6

P(LuE) = P(L) + P(E) - P(LnE)

0.6 = 0.5 + x - 0.4

0.6 = 0.1 + x

0.6 - 0.1 = x

0.5 = x

P(E) = 0.5

0.5 * 100% = 50%

In order to prove the expression for coefficient b[tex]_{2}[/tex] we have to find b[tex]_{0}[/tex] and b[tex]_{1}[/tex]

F(x) = [tex]b_{0} + b_{1} ( x - x_{0} ) + b_{2} ( x - x_{0} ) (x - x_{1} )[/tex]

9). If m∠7 = 100°,

    m∠3 = m∠7 = 100° [Since, ∠3 and ∠7 are alternate interior angles]

10). m∠7 = 95°

   m∠6 + m∠7 = 180° [Consecutive interior angles]

   m∠6 = 180° - m∠7

   m∠6 = 180° - 95°

   m∠6 = 85°

11. m∠1 = 120°

   m∠1 = m∠5 = 120° [Alternate exterior angles]

12. m∠4 = 20°

   Since, m∠4 = m∠6 = 20° [Vertically opposite angles]

   And m∠6 + m∠7 = 180° [Consecutive interior angles]

   20° + m∠7 = 180°

   m∠7 = 160°

13. m∠3 = 140°

   m∠3 + m∠6 = 180° [Linear pair of angles]

   m∠6 = 180° - m∠3

            = 180° - 140°

            = 40°

    m∠6 = m∠8 = 40° [Corresponding angles]

14. m∠4 = 30°

    m∠4 + m∠1 = 180° [Consecutive exterior angles]

    m∠1 = 180° - 30°

    m∠1 = 150°

15. m∠4 = 40°

    m∠4 = m∠2 = 40° [Corresponding angles]

16. m∠7 = 125°

    m∠6 + m∠7 = 180° [Consecutive interior angles]

    m∠6 = 180° - 125°

             = 55°

    m∠6 = m∠4 = 55° [Vertically opposite angles]

17. m∠1 + m∠3 = 230°

    Since, m∠1 = m∠3 [Corresponding angles]

    m∠3 + m∠3 = 230°

    m∠3 = [tex]\frac{230}{2}[/tex]

             = 115°

    m∠3 + m∠6 = 180° [Linear pair of angles]

    m∠6 = 180° - 115°

    m∠6 = 65°

Answer:

L=10cm , W=30cm

Step-by-step explanation:

First use the given that W=10+2*L

Use P=2W+2L=80, substitute W in the perimeter formula

2(10+2L)+2L=80 and solve for L,

20+4L+2L=80 isolate variable L and combine like terms,

6L=80-20,

L=10, so W=10+2*10=10+20=30

Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.

Comparing the two circles, the length of segment AD is 4 cm. On the first circle, the diameter is BAE is 8cm.

We should know that a circle is a figure in which all distances are equal from the center and the line from the center to the circumference is called radius.

The diameter is the line that passes through the center of the circle dividing the circle into two equal parts.

The given information are that the circles are the same

Diameter of the circles = 8cm

Radius = D/2= 8/2

Radius = 4 cm in each circle

Since the two circles shave the same diameter of 8cm and segments are different because the second has 3 segments while the first has 2 segments

The length of the segment AD = 4 because its from center to circumference that is radius

The first circle BAE is a diameter because it divides the circle into two equal halves

Therefore the length of segment AD is 4cm because it is a radius.

the diameter is BAE is 8cm.

#SPJ2

Answer- each width = 10, each length = 21

Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21

Answer:

[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]

Step-by-step explanation:

So if we first graph the given equation, we'll see the graph I've attached below.

Remember that piecewise functions are functions that change based on the circumstances. I know that sounds super confusing, but it's actually really simple!

In this case, for example, we see the line increasing from -∞ to [tex]0[/tex], and then suddenly going downwards and decreasing. That's a good spot for us to notice because that indicates a change. We notice that the function looks different when [tex]x<0[/tex] or [tex]x>0[/tex]. If you break the function into those two parts, you see that they are just linear equations, but they're only visible when x is either greater than or less than 0.

Now that we notice this pattern, we can find the equation of the lines for both lines.

The points (-3,-8) and (-1,-2) are points on the first line, the one that increases (on the left). We can use those points to find the slope of the first line. Remember the slope equation:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug in your points:

[tex]m=\frac{-2-(-8)}{-1-(-3)}[/tex]

[tex]m=\frac{6}{2}[/tex]

[tex]m=3[/tex]

So, the slope of the first line is 3. The y-intercept, looking at the graph, is 1. The equation of the first line is [tex]y=3x+1[/tex]. We'll need this later.

Let's do the same thing for the second line. Just looking at the graph, we can see that this is the same exact line, just with a negative slope. So, the equation for the second line is [tex]y=-3x+1[/tex].

So now we can set up a piecewise function.

[tex]f(x)\left \{ {{3x+1} \atop {-3x+1}} \right.[/tex]

The two functions in the bracket are the two different functions used in this graph. Now we need to figure out where each function is effective. Well, they share a y-intercept. Remember that a true function cannot have two points with the same x value. So the first function is effective to the left of x=0, while the second is effective to the right of x=0. In other words, when [tex]x\leq 0[/tex], [tex]f(x)=3x+1[/tex]. But, when [tex]x>0[/tex], [tex]f(x)=-3x+1[/tex]. Now our piecewise function looks like this:

[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]

And that is our piecewise function for the original function.

I know this is confusing, so please let me know if you have any questions! I hope this helps!
