A nontoxic furniture polish can be made by combining vinegar and olive oil. The amount of oil should be three times the amount o

Len [333]

Answer:

V=8.5

Step-by-step explanation:

o=oil. vinegar=v. furniture polish=f

O=3v

34= 3v + v

Using a system of guessing and checking if that number fits equation you can tell that 8 causes the equation to be unequal and also 9. You can learn V must be between 8 and 9 so 8.5 might fit the equation. 8.5=V

A bag contains tiles number 1-10. What is the probability of first selecting a PRIME number, replacing it, then selecting a numb

andrezito [222]

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

$P(A \cap B) = P(A) \times P(B)$

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

$P(A) = \frac{4}{10}$

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

$P(B) = \frac{3}{10}$

Probability of both:

$P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12$

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

which postulate or theorem, if any,could be used to prove the triangles congruent? if not enough information is given, write not

Rus_ich [418]

The ways we can prove the triangles congruent:

SAS (side, angle, side)
ASA (angle, side, angle)
AAS (angle, angle, side)
SSS (all sides equal)
RHS/HL (Right Angle-Hypotenuse-Side/Hypotenuse-legs)

In these cases:
A. <B = <E
<A = <D
AC=DF

AAS (angle, angle, side) could be used.

B. AB=ED
BC=EF
AC=DF

SSS (all sides equal) could be used.

C.<BEA=<CED (right opposite angles)

As there is only one pair of equal angles we can find,there is not enough information.

D.<B = <E
BC=CE
<ECD < ACE(right opposite angles)

ASA (angle, side, angle) could be used.

Hope it helps!
