(√3 + √11)² + (√3 - √11)²

(a+b)² = a² + b² + 2ab
( a - b )² = a² + b² - 2ab

Now ,

(√3 + √11)² + (√3 - √11)²

(3 + 11 + 2√3√11)+ (3 +11 - 2√3√11)

14 + 2√33+ 14 - 2√33

14 + 14 = 28

Hence , The value of (√3 + √11)² + (√3 - √11)² is 28 .

Answer:

Step-by-step explanation:

(a + b)² + (a - b)² = 2a² + 2b²

(√3 + √11)² + (√3 - √11)²

= 2√3² + 2√11²

= 28

A study of 12,000 able-bodied male students at the University of Illinois found that their times for the mile run were approxima

Answer:

$P (y < 6) = \frac{P(y- \mu)}{\sigma} \mu}{\sigma} \\\\=P(z$

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Step-by-step explanation:

Normal with mean 6.88 minutes and

a standard deviation of 0.57 minutes.

Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)

$\mu = 6.88$

$\sigma = 0.57$

y ≈ normal (μ, σ)

The z score is the value decreased by the mean divided by the standard deviation

$P (y < 6) = \frac{P(y- \mu)}{\sigma} \mu}{\sigma} \\\\=P(z$

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Answer:

$Budget = 3 b$

Step-by-step explanation:

Given

$Budget = \$30$

$Cost\ of\ box (b) = \$10$

Required

Represent as an equation;

$Budget = \$30$

Expand the above

$Budget = 3 * \$10$

Recall that b = $10 ----given

$Budget = 3 * \$10$ becomes

$Budget = 3 * b$

$Budget = 3 b$

Hello can someone help me please

Add the three different amounts she gets to find the total:

450 + 300 + 500 = 1250 mg total.

1250 is greater than 1200, so yes, she is getting enough.

6 inches because 24 is 3 times greater than 8, so you would do 18/3.
