How many real number solutions does this have 3x^2 + 8x +7=0

kompoz [17]

Answer:

zero

Step-by-step explanation:

The answer to that question is best found by looking at the value of the <em>discriminant</em>.

For quadratic ax^2 +bx +c = 0, the value of the discriminant is ...

d = b^2 -4ac

Here, you have a=3, b=8, c=7, so the discriminant is ...

d = 8^2 -4(3)(7) = 64 -84 = -20

When the discriminant is negative, both solutions are complex (not real).

There are zero real solutions to this equation.

A, B, and C are the midpoints of XY, YZ, and XZ.<br> Find the perimeter of XYZ

Monica [59]

Answer:

100 cm

since B,C are the two midpoints of ZY,XZ then BC is parallel to side XY and equal half of its length then XY equal 30 cm and simce A,B are the midpoints of XY,YZ then AB equal half XZ then XZ equal 36 cm then the perimeter of XYZ equals 36+30+34 equals 100 cm

If you roll a dice four times, what is the chance that you roll two 3s?

Rufina [12.5K]

Answer:

11.57%

Step-by-step explanation:

The probability of rolling two 3s is the product of the probability of rolling two 3s and two not-3s, and the number of ways that combination of rolls can appear.

<h3>combinations of rolls</h3>

Of the four die rolls, we want two of them to be 3s. The 3s can appear anywhere in the sequence. For example, we could have 33xx, or xx33, or any of a number of other combinations (where x is a "not 3"). The total number of ways two 3s can appear an a sequence of 4 rolls is ...

C(4, 2) = 4!/(2!(4 -2)!) = 4·3/(2·1) = 6

<h3>probability of two 3s and two not-3s</h3>

The probability of rolling a 3 on a fair 6-sided die with one face labeled 3 is presumed to be 1/6. Then the probability of rolling something else is ...

1 -1/6 = 5/6

So, two 3s and two not-3s in a given sequence have a probability of ...

(1/6)(1/6)(5/6)(5/6) = 25/1296

<h3>two 3s in 4 rolls</h3>

The probability that four rolls of the die will show exactly two 3s is the product of the probability it can happen and the number of ways it can happen:

(25/1296) × 6 = 25/216 ≈ 11.57%

The attachment shows the probability function of a calculator gives the same result.

A boat costs $12,250 & decreases in value by 11% per year how much will the boat be worth after 4 years

kirill115 [55]

So it decreases by 11% which means by the next year it's worth 89% of the original price, write 89% like a decimal. then put it to the power of 4 (4 years) and multiply by the original number
.89 ^ 4 * 12250 = 7685.92
