Answer:

(a + b) (a + b) = 35

Step-by-step explanation:

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ \\ (a + b) (a + b) = a \ast a + b \ast b + 2ab \\ \\ = 25 + 2 \times 5 \\ \\ 25 + 10 \\ \\ (a + b) (a + b) = 35$

If diameter of a circle is twice as large as the diameter of a smaller circle, What

Leona [35]

The area of a circle uses the radius of a circle, which is 1/2 the diameter.

In the calculation the radius is squared.

Since the diameter of the larger circle is twice as large the radius would be 2 times.

2 squared would be: 2^2 = 4

This means the area of the larger circle is 4 times larger which would make the ratio 4:1

Fill in the blanks below to make a true statement. In a binomial experiment with n trials and probability of success p, if np (1

Sergeu [11.5K]

Answer:

$\mu_{x}=np$

$\sigma^2_{X}=np(1-p)$

Step-by-step explanation:

∵ When x is a random variable having distribution B(n, p), then for sufficiently large value of n, the following random variable has a standard normal distribution,

$\frac{x-\mu}{\sigma}\sim N(0,1)$

Where,

$\mu=np$

$\sigma^2=np(1-p)$

Here the variable X has a binomial distribution,

Such that, np (1 - p) ≥ 10 ⇒ n is sufficiently large.

Where, n is the total numbers of trials, p is success in each trials,

So, the mean of variable X is,

$\mu_{X} = np$

And, variance of variable X is,

$\sigma^2{X}=np(1-p)$

The most likely number of bags of peanuts she

sold is 20 bags of peanut at at $4 each

<h3>Equation</h3>

Kiyo:

94 = 10 + x

94 - 10 = x

84 = x

Aleja

94 = 14 + y

94 - 14 = y

80 = y

Find the highest common factor of 84 and 80

80 = 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80.

84 = 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84

The highest common factor is 4

80 ÷ 4 = 20 bags of peanut

84 ÷ 4 = 21 bags of peanut
