Answer:

A: -1/3x

Step-by-step explanation:

We can convert -1/3 to -2/6 by multiplying -1/3 by 2/2. As we know, 5-2 is 3. That makes 3/6. 3/6 is equivalent to 1/2. That means it has to be A.

0.25 r – 0.125 + 0.5 r = 0.5 + r

faltersainse [42]

0.25r - 0.125 + 0.5r = 0.5 + r
Step 1: Move all similar terms (r) to the same side of the equation by
subtracting "r" from each side of the equation
0.25r - 0.125 + 0.5r - r = 0.5
Move terms without r to the other side of the equation, by adding +0.125 to each side of the equation
0.25r + 0.5r - r = 0.5 + 0.125
Add similar terms, note that r is equal to 1r
0.75r - 1r = 0.625
-0.25r = 0.625
Solve for r by dividing both sides of the equation by -0.25
r= 0.625/(-0.25)
r=-2.5

❀ $\huge\underline{ \underline{Solution :-}}$

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} )$

To solve, use the algebraic identity ➺

<u>(x + a)( x + b) = x² + (a + b)x + ab</u>

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} ) \\ = ({y}^{2}) ^{2} + ( \frac{5}{7} + - \frac{14}{5} ) {y}^{2} + \frac{5}{7} \times - \frac{14}{5} \\ = {y}^{4} - \frac{73}{35} {y}^{2} - 2$

Industry standards suggest that 13 percent of new vehicles require warranty service within the first year. Jones Nissan in Sumte

zvonat [6]

Answer: 0.1880

Step-by-step explanation:

The binomial distribution formula is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$

where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.

Given : The probability of new vehicles require warranty service within the first year : p =0.13.

Number of trials : n= 12

Now, the required probability will be :

$P(x=0)=^{12}C_0(0.13)^{0}(1-0.13)^{12-0}\\\\=(1)(0.13)^{0}(0.87)^{12}=0.188031682201\approx0.1880$

Thus, the probability that none of these vehicles requires warranty service = 0.1880
