Answer:

Probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]

Step-by-step explanation:

According to the classical approach to assigning probability, if an experiment has [tex]n[/tex] simple outcomes, this method  would assign a probability of [tex]\frac{1}{n}[/tex] to each outcome. In  other words, each outcome is assumed to have an equal  probability of occurrence.

So, probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]

Complete question :

At a certain school, 25% of the students wear a watch and 30% wear a bracelet. 60% of the students wear neither a watch nor a bracelet.

a) One of the students is chosen at random. What is the probability that this student is wearing a watch or a bracelet?

b) What is the probability that this student is wearing both a watch and a bracelet?

Answer:

0.40 ; 0.15

Step-by-step explanation:

Let :

w = watch

b = bracelet

P(W) = 0.25

P(B) = 0.3

P(either a watch or a bracelet) = P(WuB)

P(neither a watch nor a bracelet) = 1 - P(WuB)

1 - P(WuB) = 0.6

a.) probability that student is wearing a watch or a bracelet = P(WuB)

P(neither a watch nor a bracelet) = 1 - P(WuB)

0.6 = 1 - P(WnB)

P(WnB) = 1 - 0.6

P(WnB) = 0.4

B.) probability that student is wearing both a watch and a bracelet : P(WnB)

Using the probability relation :

P(WuB) = P(W) + P(B) - P(WnB)

0.4 = 0.25 + 0.30 - P(WnB)

0.4 = 0.55 - P(WnB)

P(WnB) = 0.55 - 0.40

P(WnB) = 0.15

Answer:

what????????????????

Answer:

(-1 1/2,3

Step-by-step explanation:

Answer:

(-1 1/2,3)

Step-by-step explanation:

Answer:

1. U = 54   T = 72

2. M = 76   N = 76

3. F = 134   EF = 18

4. P = 60   Q = 60   R = 60

Step-by-step explanation:

1. the triangle given is an isosceles triangle. this means that the two angles that aren't connected with a congruent side, have the same measures. These angles are also called base angles

in this case, those two angles are S and U

since we know S is 54, U will also be 54

to find the third angle, add all your know angles, then subtract it from 180. We do this because all the angles in a triangle will always add up to 180.

180 - (54 + 54) = 72

U = 54

T = 72

2. In this case M and N are your base angles. We know that the base angles are equal, and that when you add them with L, you should get 180.

we can start by subtracting L from 180 to find the sum of M and N

180 - 28 = 152

now divide this by 2 to find the individual angles:

152 / 2 = 76

so: M = 76 and N = 76

3. For this one, we can do something similar to what we did in question 1 to find F. Just add the base angle, and subtract it from 180 to find the third angle:

180 - (23 + 23) = 134

In isosceles triangles, there are two lines that are congruent, these two lines are the lines that meet at the abnormal angle. In this case, GF and EF are those lines.

so if GF is 18, then EF is also 18

4. This triangle is an equilateral triangle. This means that all sides and angles are congruent. to find the angles, all we have to do is divide 180 by 3, since there are 3 equal angles.

180 / 3 = 60

every angle is 60

Answer:

option c

Step-by-step explanation:

b²-4ac is the discriminant

Answer:

x = 12

m∠A = 104º

m∠B = 32º

m∠C = 44º

shortest side = B

middle side = C

longest side = A

Step-by-step explanation:

Recall that all angles in a triangle add up to 180º. Also recall that the side opposite largest angle is the longest side, and vice versa for the side opposite the smallest angle.

Answer:

The value of x is -2 and 2.

Step-by-step explanation:

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :

x² - 3x - 1 = -3x + 3

x² - 3x - 1 + 3x - 3 = 0

x² - 4 = 0

Next, you have to factorize and solve it :

x² - 4 = 0

x² + 2x - 2x - 4 = 0

x(x + 2) - 2(x + 2) = 0

(x + 2)(x - 2) = 0

x + 2 = 0

x = -2

x - 2 = 0

x = 2

Answer:

Given:

Consider the given expression is

[tex]5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}[/tex]

Using properties of exponents, we get

[tex]=5^{-\frac{5}{2}+\frac{9}{2}}[/tex]           [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]=5^{\frac{-5+9}{2}}[/tex]

[tex]=5^{\frac{4}{2}}[/tex]

[tex]=5^{2}[/tex]

[tex]=25[/tex]

Therefore, the simplified form of given expression is 25.

Question attached. Will mark brainliest.

x + 2

Answer:

1) point slope form: y-y1=m(x-x1) so  y-3=5/3(x-1)

y-3=5/3x-5/3

y=5/3x+4/3 <---bc 9/3-5/3=4/3

2)Plug in 1,2,3,4,5 for x and solve

y=5/3*1-4/3

y=1/3  (1, 1/3)

y=5/3*2-4/3

y=2 (2,2)

y=5/3*3-4/3

y=11/3 (3, 11/3)

y=5/3*4-4/3

y=16/3 (4, 16,3)

y=5/3*5-4/3

y=24/3 or 8 (5,8)

3) Plot the ordered pairs I wrote above

Answer: k=65

Step-by-step explanation:

Answer:

k=65

Step-by-step explanation:

You would need to divide -0.6 on both sides to isolate k

-39 = -0.6k     Original equation

-39÷ -0.6 = -0.6k÷-0.6    Isolating the variable

-39÷-0.6 = k     SImplification

65 = k              The answer!!!

When multiplying or dividing 2 negative numbers, remember that the result will be positive

I hope this helps!!!

Answer:

There is sufficient evidence at 0.05 significant level to support company's claim.

Step-by-step explanation:

We have these informations from the question

n = 1400

P^ = 31% = 0.31

Alpha level = 5% = 0.05

Then we come up with the hypothesis

H0: P = 0.28

H1: P>0.28

From here we calculate the test statistic

z = p^ - p/√pq/n

P = 0.28

q = 1-0.28

= 0.72

z = 0.31-0.28/√(0.31*0.72)/1400

= 0.03/√0.0001594

= 0.03/0.012

= 2.5

Then we have a p value = 0.00621

The p value is less than significance level

0.00621<0.05

So the null hypothesis is rejected.

We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.
