Answer:

Option A = 6

Step-by-step explanation:

3x- 5 = x+ 7 ( as diagonals r equal in a recangle)

3x-x = 7+ 5

2x = 12

x = 12/ 2 = 6

Answer:

option (b) 0.0228

Step-by-step explanation:

Data provided in the question:

Sample size, n = 100

Sample mean, μ = $20

Standard deviation, s = $5

Confidence interval = between $19 and $21

Now,

Confidence interval = μ ± $z\frac{s}{\sqrt n}$

thus,

Upper limit of the Confidence interval = μ + $z\frac{s}{\sqrt n}$

$21 = $20 + $z\frac{5}{\sqrt{100}}$

z = 2

Now,

P(z = 2) = 0.02275 [From standard z vs p value table]

P(z = 2) ≈ 0.0228

Hence,

the correct answer is option (b) 0.0228

$\\ \sf\longmapsto f(x)=2x^2-3x+1$

$\\ \sf\longmapsto f(1)=2(1)^2-3(1)+1$

$\\ \sf\longmapsto f(1)=2(1)-3+1$

$\\ \sf\longmapsto f(1)=0$

Now

$\\ \sf\longmapsto f(2)=2(2)^2-3(2)+1$

$\\ \sf\longmapsto f(2)=2(4)-6+1$

$\\ \sf\longmapsto f(2)=8-5$

$\\ \sf\longmapsto f(2)=3$
