Two die are rolled simultaneously. what is the probability of getting a sum of at least 5?

1 answer:

6 0

6x6 to find the probability for every single roll which is 36.
Ways to make 5 ; 1+4, 4+1, 2+3, 3+2. 4 ways, therefore it’s 4/36 which simplifies to 1/9

What are the zeros of the quadratic function f(x) equals 6X squared +12 X -7

The zeroes of the function will be $\rm -1 \pm \dfrac{\sqrt{78}}{6}}$

<h3>What is a Quadratic Function ?</h3>

A quadratic function is given by ax² +bx+c = f(x)

The given quadratic function is

f(x) = 6x² +12x - 7

The zeroes of the function will be given by

f(0) = 0

6x² +12x - 7 = 0

The zeroes are given by

$\rm \dfrac {-b \pm \sqrt{b^2 -4ac}}{2a}$

here

a = 6

b = 12

c = -7

Therefore the zeroes of the function will be

$\rm \dfrac {-12 \pm \sqrt{12^2 -4*6*(-7)}}{2 *6}$

$\rm \dfrac {-12 \pm \sqrt{312}}{12}$

$\rm -1 \pm \dfrac{\sqrt{78}}{6}}$

Therefore these are the two zeroes of the function.

Emily's family traveled 3/10of the distance to her aunt’s house on Saturday. They traveled 4/7 of the remaining distance on Sund

WARRIOR [948]

Answer: 4/10 or 2/5

Step-by-step explanation:

Let us represent, the total distance travelled as:

Ballio's family traveled 3/10 of the distance to his aunt's house on Saturday.

Distance left to travel = 1 - 3/10

= 7/10

They traveled 4 /7 of the remaining distance on Sunday.

The fraction of the total distance to his aunt's house was traveled on Sunday is calculated as:

4/7 × Distance left to travel

= 4/7 × 7/10

= 4/10

but if i'm wrong then the answer might be 2/5

A parking space is 20 feet long. A pickup truck is 6 yards long. How many inches longer is the parking space than the truck

masya89 [10]

1 yard = 3 feet.

Multiply the length of the truck by 3 to get total feet:

6 x 3 = 18 feet.

Subtract the length of the truck from the length of the parking space:

20 - 18 = 2 feet

1 foot = 12 inches.

Multiply 2 feet by 12:

2 x 12 = 24 inches longer.

For a given input value b, the function f outputs a value a to satisfy the following equation. 4a+7b=−52 Write a formula for ) f

Sergio [31]

Answer: Our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$

Step-by-step explanation:

Since we have given that

$4a+7b=-52\\$

We need to write a formula for f(b) in terms of b So, it becomes

$4a=-52-7b\\\\a=\frac{-52-7b}{4}\\\\a=\frac{-52}{4}-\frac{7b}{4}\\\\a=-13-\frac{7b}{4}$

Hence, our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$
