Answer:

Option (c) is correct.

Step-by-step explanation:

The given equation is :

6x+10=-8

We need to solve the above equation.

Taking like terms together,

10+8 = -6x

18 = -6x

x = -3

So, the value of x is (-3).

The line that represents x = -3 is shown in option (3). Hence, the correct option is (c).

"Write a set of inequalities and solve to find the range of possibilities for x. You will need to write two separate inequalitie

san4es73 [151]

Answer:

x > 5/3
x < 8

Step-by-step explanation:

First, the side lengths should be greater than zero:

3x - 5 > 0
2x + 3 > 0

Second, The triangles have a common side and the given sides are opposite of 27° and 37° angles.

This tells us the side opposite of greater angle is greater:

2x + 3 > 3x - 5

Simplify each inequality:

3x - 5 > 0 ⇒ 3x > 5 ⇒ x > 5/3
2x + 3 > 0 ⇒ 2x > - 3 ⇒ x > - 3/2
2x + 3 > 3x - 5 ⇒ 3x - 2x < 3 + 5 ⇒ x < 8

Common solution is:

x > 5/3
x < 8

The given equation is:
ax2 + bx + c = 0
We have the resolvent is:
x = (- b +/- root (b2 - 4ac)) / (2a)
The discriminant is:
b2 - 4ac = 0
The solution will be:
x = (- b) / (2a)
Thus, the equation has a real solution.
Answer:
option B

It has been estimated that only about 30% of California residents have adequate earthquake supplies. Suppose you randomly survey

mote1985 [20]

Answer:

$P(X\geq 8)=0.0043\\\\$

It's more likely that all of the residents surveyed will have adequate earthquake supplies since it has a probability of 98.02% which is very close to 100%.

Step-by-step explanation:

-This is a binomial probability problem with the function:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

-Given p=0.3, n=11, the is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 8)=P(X=8)+P(X=9)+P(X=10)+P(X=11)\\\\={11\choose 8}0.3^8(0.7)^3+{11\choose 9}0.3^9(0.7)^2+{11\choose 10}0.3^{10}(0.7)^1+{11\choose 11}0.3^{11}(0.7)^0\\\\=0.0037+0.0005+0.00005+0.000002\\\\=0.0043$

Hence, the probability that at least 8 have adequate supplies 0.0043

#The probability that non has adequate supplies is calculated as;

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X= 0)={11\choose 0}0.3^{0}(0.7)^{11}\\\\=0.0198$

#The probability that all have adequate supplies is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X= All)=1-{11\choose 0}0.3^{0}(0.7)^{11}\\\\=1-0.0198\\\\=0.9802$

Hence, it's more likely that all of the residents surveyed will have adequate earthquake supplies since $P(All)>P(None)\ \$ and that this probability is 0.9802 or 98.02% a figure close to 1
