To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees

asambeis [7]

Answer:

The temperature is $50^{\circ}F$

Step-by-step explanation:

Given

$F= (C*1.8) + 32$

Required

Find F when $C = 10$

$F= (C*1.8) + 32$

Substitute 10 for C

$F = 10 * 1.8 + 32$

$F = 18 + 32$

$F = 50$

Given the system of equations, what is the x-coordinate of the solution?

Nimfa-mama [501]

Answer: Choice C) -11

-----------------------------------

Explanation:

The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x.
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)

Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 17 Pennies 10 Dimes 19 Nickels

MatroZZZ [7]

Answer:

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.

Step-by-step explanation:

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

Probability of grabbing a nickel:

19 nickels out of 17+10+19+23 = 69 coins, so:

$P(A) = \frac{19}{69}$

Probability of grabbing a penny, considering the first coin grabbed was a nickel:

17 pennies out of 68 coins. So

$P(B|A) = \frac{17}{68} = \frac{1}{4}$

What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?

$P(A \cap B) = P(A)P(B|A) = \frac{19}{69} \times \frac{1}{4} = \frac{19}{69*4} = 0.0688$

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
