Jenna and Heidi together have $60. Jenna has $9 more than twice Heidi’s amount. How much money does each have?

Marina86 [1]

Jenna has $43 and Heidi has $17.

Step-by-step explanation:

Total amount = $60

Let,

Amount of Jenna = x

Amount of Heidi = y

According to given statement;

x+y=60 Eqn 1

x=2y+9 Eqn 2

Putting value of Eqn 2 in Eqn 1;

$(2y+9)+y=60\\2y+9+y=60\\3y=60-9\\3y=51$

Dividing both sides by 3,

$\frac{3y}{3}=\frac{51}{3}\\y=17\\$

Putting y=17 in Eqn 2

$x=2(17)+9\\x=34+9\\x=43$

Jenna has $43 and Heidi has $17.

The rational number lies between −67/7 and−78/8

zheka24 [161]

9514 1404 393

Answer:

-135/14

Step-by-step explanation:

There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...

-67/7 = -9 4/7 = -9.571428... (repeating)

-78/8 = -9 3/4 = -9.75

So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.

If you like, you can convert these numbers to ones with a common denominator (56).

-67/7 = -536/56

-78/8 = -546/56

These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.

On a December day, the probability of snow is 0.30. The probability of a "cold" day is 0.50. The probability of snow and "cold"

Margarita [4]

Answer:

Yes, snow and cold weather are independent.

Step-by-step explanation:

We are given the following in the question:

C: Cold weather

S: Snow

P(C) = 0.50

P(S) =0.30

$P(S\cap C) = 0.15$

We have to check whether snow and cold whether are independent events.

If the events A and B are independent then,

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

Checking,

$p(S\cap C) = P(S)\times P(C)\\0.15 = 0.30\times 0.50$

Thus, the two events are independent.

For mutually exclusive events

$P(A\cap B) = 0$

Thus, the given events are not mutually exclusive.
