Answer:
spinner 2 is 14
Step-by-step explanation:
7+3=10
10+4=13
<u>ANSWER</u>=<u>5.2</u>
<u />
<u>EXPLANATION</u>
This triangle shows a example of the Pythagorean Theorem, which means the equation is gonna be
a^2+b^2=c^2
The variables <u>a </u>and <u>b </u>are the straight sides of the triangle, while the variable <u>c </u> is the curved side on the triangle, or what we are trying to find in this question.
Firstly let’s take the two sides that already have a number shown, also known in the Pythagorean Theorem as sides <u>a </u>and <u>b</u>.
2^2+4.8^2=c^2
Now we want to square the two given numbers to get the equation
4+23.04=c^2
Now we add the two given numbers that we have now squared to get the equation
27.04=c^2
The final step will now be to take the number (27.04) and square root it, which should give you the answer, <u>5.2</u>
Answer:
area = 250 in²
Step-by-step explanation:
5 x 2.5 = 12.5 in
8 x 2.5 = 20 in
area = 20 x 12.5 = 250 in²
Answer:
1) is not possible
2) P(A∪B) = 0.7
3) 1- P(A∪B) =0.3
4) a) C=A∩B' and P(C)= 0.3
b) P(D)= 0.4
Step-by-step explanation:
1) since the intersection of 2 events cannot be bigger than the smaller event then is not possible that P(A∩B)=0.5 since P(B)=0.4 . Thus the maximum possible value of P(A∩B) is 0.4
2) denoting A= getting Visa card , B= getting MasterCard the probability of getting one of the types of cards is given by
P(A∪B)= P(A)+P(B) - P(A∩B) = 0.6+0.4-0.3 = 0.7
P(A∪B) = 0.7
3) the probability that a student has neither type of card is 1- P(A∪B) = 1-0.7 = 0.3
4) the event C that the selected student has a visa card but not a MasterCard is given by C=A∩B' , where B' is the complement of B. Then
P(C)= P(A∩B') = P(A) - P(A∩B) = 0.6 - 0.3 = 0.3
the probability for the event D=a student has exactly one of the cards is
P(D)= P(A∩B') + P(A'∩B) = P(A∪B) - P(A∩B) = 0.7 - 0.3 = 0.4
