Answer:

○ $6 ÷ -3$

Step-by-step explanation:

Although $-3\frac{3}{8}$ is $\frac{1}{8}$ closer to $-3\frac{1}{2}$ , in this case, we still have to round up to −3, and $5\frac{3}{4}$ is only $\frac{1}{4}$ away from 6.

I am joyous to assist you anytime.

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Here's the solution ~

Let's find the gradient of the shown line, using coordinates of any two points on it, like I'm gonna use (0 , 2) and (1 , -1)

Use the following equation :

$\qquad \sf \dashrightarrow \: gradient = \dfrac{y_2 - y_ 1}{x_2 - x_1}$

$\qquad \sf \dashrightarrow \: g = \dfrac{2 - ( - 1)}{0 - 1}$

$\qquad \sf \dashrightarrow \: g = \dfrac{2 + 1}{ - 1}$

$\qquad \sf \dashrightarrow \: g = - 3$

Hence, the gradient = -3 for the given line ~

Solve the equation. dy dx = ay + b cy + d , where a, b, c, and d are constants. (assume a ≠ 0 and ay + b ≠ 0.)

Reil [10]

It solves it in x. the solution for y includes heavy use of the product log function.

dy/dx = ay + b/cy +d

(cy +d/ ay + b) dy = dx

∫ (cy +d/ ay + b) dy = x (t) + C

Into solving the integral, integration by parts followed by u substitution and another integration by parts.

∫ (cy +d/ ay + b) dy

u = cy + d dv = dy/ay + b

du = c dy v = ln I ay + b l / a

Then, use u substitution for the new integral

u = ay + b

du = a dy

∫ ln l ay + b I dy = ∫ ln IuI /a du = 1/a ∫ ln luI du

Integrating the natural log includes thus far another integration by parts

r = ln IuI ds = du

dr = du / u (s) = du

∫ ln IuI / du = u ln IuI - ∫ du = u ln IuI - ∫ a dy = (ay + b) ln Iay +bl – ay

The original integral of expression

∫ (cy +d/ ay + b) dy = cy + d/a ln lay+bl – c/a² [(ay+b) ln lay+bl – ay]

Then simplify

∫ (cy +d/ ay + b) dy = cy + d/a ln lay+bl – c/a²[(ay+b) ln lay+bl – ay]

= a (cy + d)/a² ln lay+bl – c (ay+b)/ a²ln lay+bl + c/a² ay

= cay + ad – cay – cb/ a² ln lay+bl + cay/a²

= ad – cb/a²ln lay+bl + cy/a

The final answer will be

x(t) + C = ad – cb/a² ln lay+bl + cy/a

x(t) = ad – cb/a² ln lay+bl + cy/a + k

Delta makes 12-volt car batteries. These batteries are known to be normally

blondinia [14]

Answer:

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%

Step-by-step explanation:

Step(i):-

Given that the sample size n =12 -volt car batteries

Let 'X' be a Random variable in a normal distribution

Given that mean of the normal distribution = 45 months

Given that the Standard deviation of the normal distribution = 8months

Step(ii):-

Let X₁ = 3 years = 12 × 3 = 36 months

$Z_{1} = \frac{x_{1} -mean}{S.D} = \frac{36-45}{8} = -1.125$

Let X₂ = 4 years = 12 × 4 = 48 months

$Z_{2} = \frac{x_{2} -mean}{S.D} = \frac{48-45}{8} = 0.375$

Step(iii):-

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = P(-1.125≤Z≤0.375)

= P(Z≤0.375) - P(Z≤-1.125)

= 0.5 +A(0.375) - (0.5-A(1.125)

= 0.5 + 0.1480 - (0.5 -0.3708)

= 0.1480 + 0.3708

= 0.5188

Final answer:-

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%

Select the correct answer.

The answer to this Question is A

What is Absolute Value Function or so called Modulus Function or Mod function?

It is a function that takes all real values as input and returns same values but +ve in nature eg if you give input as 2, output will be 2 and if you give input as -2, you will get output 2 again

Solution:

We have expression Ix-5I + 2

we know that I anything I , called as mod of anything, is always greater than or equal to zero so if we take its minimum value as 0 and we get 0 + 2 = 2

means this expression cant be less than 2 hence it will be greater than or equal to 2

because minimum value of mod is 0 and we are adding 2 to it hence overall the expression will be greater than 2 only
