Sasha wrote each of the numbers 21 through 40 on a different index card. She will randomly pick one card. A is the event of picking a number that is divisible by 3. B is the event of picking a prime number.
Answer:
[tex]Pr(A\ or\ B) = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]S = \{21,22,23,24,......40\}[/tex]
[tex]n(S) = 20[/tex]
[tex]A = \{21,24,27,30,33,36,39\}[/tex] -- Divisible by 3
[tex]B = \{23, 29, 31, 37\}[/tex] --- Prime numbers
Required
[tex]Pr(A\ or\ B)[/tex]
This is calculated as:
[tex]Pr(A\ or\ B) = Pr(A) + Pr(B) - Pr(A\ n\ B)[/tex]
Using probability formula, we have:
[tex]Pr(A\ or\ B) = \frac{n(A) + n(B) - n(A\ n\ B)}{n(S)}[/tex]
Where:
[tex]A = \{21,24,27,30,33,36,39\}[/tex]
[tex]n(A) = 7[/tex]
[tex]B = \{23, 29, 31, 37\}[/tex]
[tex]n(B) = 4[/tex]
[tex]A\ n\ B =\{\}[/tex]
[tex]n(A\ n\ B) = 0[/tex]
So:
[tex]Pr(A\ or\ B) = \frac{n(A) + n(B) - n(A\ n\ B)}{n(S)}[/tex]
[tex]Pr(A\ or\ B) = \frac{7 + 3 - 0}{20}[/tex]
[tex]Pr(A\ or\ B) = \frac{10}{20}[/tex]
[tex]Pr(A\ or\ B) = \frac{1}{2}[/tex]
if the probability of rain tomorrow is 0.15 what is the probability that it will not rain
Answer:
85% or 99.85%
Step-by-step explanation:
If you mean 15% by 0.15 then the probability that it will not rain is 85% because, 100-15=85.
If you mean 0.15% by 0.15 then the probability that it will not rain is 99.85% because, 100-0.15 is 99.85.

In ⊙C, DE ≅ FG, Which statement must be true? Select all that apply.
Answer:
E because is covered all angle
< DCE ≅ < GCF must be true
Hence Option A and E are true statements.
What are angles of circle?A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. In that case, the sector has 1/6 the area of the whole circle.
According to the given figure:
DE ≅ FG
So < DCE ≅ < GCF must be true
Because DE ≅ FG
< DCE ≅ <GCF is similar to DE ≅ FG
Hence, < DCE ≅ < GCF must be true
Hence Option A and E are true statements.

In parallelogram MNPT, IZM= (6x + 10)° and
mZN= (5x + 10.5)° . How many degrees is ZT?
Answer:
83 degrees
Step-by-step explanation:
We can use the consecutive angle theorem to find the the value of x.
We can do that by doing 5x+10.5+6x+10 = 180
After simplifying, we get 11x+20.5=180
Subtract 20.5 on both sides and you get 11x=159.5.
Divide by 11 on both sides and you get x=14.5
Now we can use opposite angle theorem and set angle N and angle T equal.
That means we could write 5x+10.5 = m<T
We can substitute 14.5 for x and we get 72.5+10.5 = m<T
Simplify and you get 83 = m<T

Writing a linear equations
Answer:
y = 1/2 x - 2
Step-by-step explanation:
The standard linear equationof a line is expressed as y = mx+b
Using the coordinate points (0, -2) and (2, -1)
Slope m = -1-(-2)/2-0
m = -1+2/2
m = 1/2
Since the line cuts the y axis sat y = -2, hence the intercept b = -2
Get the required equation;
Recall that y = mx+b
y = 1/2 x + (-2)
y = 1/2 x - 2
This give the required linear equation

Explain completely why a quadratic equation cannot have one real root and one complex root. Be clear,
and make it evident that you understand this. (1 point)
Let x = p+qi be the complex root and x = r be the the real root. The p and q are real numbers.
If x = p+qi, then x-p-qi = 0 which indicates (x-p-qi) is a factor.If x = r, then it leads to x-r = 0. This makes (x-r) the other factor.Multiply the two factors like so:
(x-p-qi)(x-r)
y(x-r) ..... let y = x-p-qi
xy - ry ..... distribute
x( y ) - r( y )
x( x-p-qi ) - r( x-p-qi ) ........ plug in y = x-p-qi
x^2 - px - (qi)x - rx + pr + qr*i ........ distribute
x^2 + (-px-qi*x-rx) + (pr+qr*i)
x^2 + (-p-qi*-r)x + (pr+qr*i)
x^2 + ((-p-r)-qi*)x + (pr+qr*i)
We end up with an expression in the form ax^2 + bx + c where the coefficients are:
a = 1 = real numberb = (-p-r) - qi = complex numberc = pr + qr*i = complex numberThe coefficients b and c are complex numbers. So it is possible to have one real root and exactly one complex root; however, as shown above, it leads to some of the coefficients being complex numbers. I'm assuming your teacher wants all coefficients to be real numbers. If that's the case, then a quadratic equation cannot have one real root and one complex root. You would need to have the complex roots come in conjugate pairs. Meaning that if a quadratic equation with real coefficients has a complex root, then there's another complex root as its nearly "twin" pair so to speak.
Recall that quadratic equations have at most 2 roots according to the fundamental theorem of algebra. Having 2 complex conjugate pairs for the roots will then mean there isn't enough room for that third real root. In other words, here are all the possible scenarios:
A) There are two different real rootsB) There is exactly one real rootC) There are no real roots. Instead, there are two complex roots that come in conjugate pairs.Again this only applies if all coefficients a,b,c are real numbers. For scenario B, the root repeats itself and we consider it a double root. For instance, x^2+10x+25 = 0 has the root x = -5 repeat itself. In scenarios A and B, we don't have any complex roots happen.
Because always that we have a discriminant different than zero, we have two solutions.
When a quadratic equation has complex roots?
A quadratic equation has complex roots when its discriminant is negative, where for the general quadratic:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
And the solutions of the roots are:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}[/tex]
Because we have two possible signs for the square root of the discriminant, we always will have two solutions when the discriminant is different than zero.

A band sold out 2 of it's last 6 shows. What is the experimental probability that the band's next show will be sold out
Answer:
1/3
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
Based on experience, the band sells out 2 out of its 6 shows. So, the experimental probability of selling out its next show = 2/6

If a fridge was sold at a discounted price of GH¢ 7600, what is the original price of the fridge if the discount is 25%
Answer:
10,000.33 GH¢
Step-by-step explanation:
Let's say p = original price and d is discount
so discounted price = p*(1-d%)
From the given data,
7600 = p * (1-0.25)
p = 7600/0.75
p = 10,000.33

Answer:
5/8 - 1/4
Step-by-step explanation:
because it makes more sense I don't know how to explain
Answer:
4th option.
Step-by-step explanation:
The number getting subtracted is 5/8 since there are 5 boxes shaded in.
The number subtracting from it is 2/8 but that is not an option so the only other option equivalent to 2/8 is 1/4.
5/8 - 1/4 = 3/8 so the answer would also need to include 3/8 as the difference.
The only choice with all this is the 4th one

fred has 15000 in his savings account with an interest rate of 1.8%. assuming he doesn't add or subtract from this amount, find the estimated account balance after 22 years
Answer:
A = $20,940
Step-by-step explanation:
Interest = Principal x Rate x Time
I = prt
I = 15000(.018)(22)
I = 5940
Interest = $5,940
Total Amount = Principal + Interest
A = P + I
A = 15000 + 5940
A = 20940
