a standard six sided die. Janice rolled either a 2 or a 5 on the last 6 rolls of the die. What is the probability of Janice roll
Igoryamba

We have that   the probability of Janice rolling a 2 or 5 on her 7th toss of the dice is

\frac{1}{3}^7.

From the question we are told that

Janice rolled either a 2 or a 5 on the last 6 rolls of the die

Janice rolling a 2 or 5 on her 7th toss of the dice

P(2/ 5)=1/6+1/6\\\\P(2/ 5)=2/6\\\\P(2/ 5)=1/3.

Where

P(2/5 ) =(1/3)^6.

Janice roll the standard die 7th time the probability of getting 2 or 5 is

P(2/5 ) =\frac{1}{3}^7.

The difference between nine times number and thirty
svetlana [45]
9x-30 I’m pretty sure!
We are finding the difference, which means subtract! Nine times a number would be 9x and since it’s difference you would subtract it by 30.

Help Me pls its due today pls

The answer is 0 quarts.

Remember
1 gallon contains 64ounces
1 cup contains 8ounces
1 pint contains 16ounces

We know that 2 gallons (128oz total) are needed to fill the bucket.

First, Omar pours 64 ounces into the bucket so we have 128 - 64 = 64 ounces left to fill.

Second, Penny pours 8 cups which is the same as 64 ounces (8cups x 8 ounces = 64 ounces total) into the bucket.

Stop here and add up the water in the bucket.

The bucket has only 128 ounces capacity total which means Omar and Penny have filled up the bucket with 64 ounces each. 64 x 2 = 128 ounces

The bucket is full, Ronnie actually makes it overflow. So Sierra will pour 0 quarts of water into the bucket.

Show work please :: I forgot how to solve
Vesna [10]
40 pages = 80 minutes
210 pages = ? minutes
Well, take the first fact; 40 pages in 80 minutes and use it to find how many pages per minute.
40/80=1/2
1/2 pages = 1 minute
1 page = 2 minutes
210 pages = ? minutes
210*2=420
420 minutes = 7 hours
210 pages = 7 hours
Hope this helped :)

Y=3/8x−4 write in standard form
Naddik [55]
Answer:

y=3/8x-4
Move the expression to the left
y-3/8x=-4
Multiply both sides by 8
8y-3x=-32
Reorder the terms
-3x+8y=-32
Change the signs and standard form is...
3x-8y=32
