Answer:

1. x= -2 2. ×= -10 3. x= -99

Step-by-step explanation:

1. x+6 = 4

x = 4-6

x = -2

2. x-(-4) = -6

x+4 = -6

x = -6 - 4

x = -10

3. 2(x-1) = -200

2x - 2 = -200

2x = -200 +2

2x = -198

x = -99

Answer:

-2 , -10 & -99

Step-by-step explanation:

⇒ x + 6 = 4

⇒ x = 4-6

⇒ x = (-2)

⇒x - (-4) = -6

⇒ x + 4 = -6

⇒ x = -6-4

⇒ x = -10

⇒2(x-1) = -200

⇒ x - 1 = -200/2

⇒ x - 1 = -100

⇒ x = 1 - 100

⇒ x = (-99)

What value of (n) makes the equation true ? -2(n)+1.8=3.2 A. -0.7 B. 0.7 C. -3.4 D -2.5

Genrish500 [490]

The answer is A -0.7
-2(n) + 1.8 simplifies to:
-2n + 1.8 = 3.2
- 1.8 -1.8
-2n = 1.4
n = -7

The force (F) needed to cause the acceleration (a) of an object of mass, m, is given by the equation, F = ma where m is the obje

Liono4ka [1.6K]

Answer: According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Solve sin^2x+cos2x-1/4=0

sweet-ann [11.9K]

$sin^{2}x + cos2x - \frac{1}{4} = 0$
$sin^{2}x + cos^{2}x - sin^{2}x = \frac{1}{4}$
$cos^{2}x = \frac{1}{4}$
$cos(x) = \pm \frac{1}{2}$

$x = \pm \frac{\pi}{3}$
General solutions: $x = \pi(n - \frac{1}{3})$ and $x = \pi(n + \frac{1}{3})$

Select the instances in which the variable described is binomial.1) A coin flip has two outcomes: heads or tails. The probabilit

Dmitriy789 [7]

Answer: 2) A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.

• 3) There are two choices of burritos at a restaurant, vegetarian or beef. The random variable represents the total number out of 254 customers who ordered beef.

• 4) Based on the parents' genetics, each of 6 children from a particular pair of parents has a 0.30 probability of having blue eyes. The random variable represents the total number of children from this pair of parents with blue eyes

Step-by-step explanation:

The binomial distribution simply means the probability of success or failure in an experiment. The instances in which the variable described is binomial are given below:

• 2) A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.

• 3) There are two choices of burritos at a restaurant, vegetarian or beef. The random variable represents the total number out of 254 customers who ordered beef.

Option 1 isn't binomial since the number of trails that are given isn't fixed. Option 5 isn't binomial as well

Therefore, the correct options are 2,3 and 4.
