Gordon is 5 years older then Krutika. David is 6 years younger than krutika if the total of their age is 86 how old is the eldes

Alisiya [41]

Answer:

Gordan is the eldest and he is 34.

Step-by-step explanation:

Well let Krutica’s age = x

K = x

G = x+5

D = x-6

K+G+D = 86

x + x+5 + x-6 = 86

3x - 1 = 86

3x = 87

x = 29

Gordon is the oldest so G = 29+5

G = 34

Expand. If necessary, combine like terms. (3 + 4x) (3 - 4x)

shepuryov [24]

(3 + 4x) (3 - 4x)

We know the algebraic identity: (a - b)(a + b) = a^2 + b^2. Therefore, we should square 3 and 4x.

= (3)^2 - (4x)^2
9 - 16x^2

Answer:

9 - 16x^2

In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product,

Vadim26 [7]

Answer: 0.2872

Step-by-step explanation:

Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so.

i.e. n= 1000 and x= 260

⇒ Sample proportion : $\hat{p}=\dfrac{260}{1000}=0.26$

z-value for 95% confidence interval : $z_c=1.960$

Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-

$\hat{p}+ z_c\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$=0.26+ (1.96)\sqrt{\dfrac{0.26(1-0.26)}{1000}}$

$=0.26+ (1.96)(0.01387)=0.26+0.0271852=0.2871852\approx0.2872$

∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872
