Answer:

The *probability* will be "

Given:

**Mean**,

- 9

**Standard deviation**,

- 0.6

**Number** of babies,

- 4

The **standard error** of sample will be:

→

hence,

→ P(4 babies will be between **8.4 - 9.6 pounds**)

Thus the above response is right.

Answer:

Complete question:

Some sources report that the weights of full-term newborn babies in a certain town have a mean of 9 pounds and a standard deviation of 0.6 pounds and are normally distributed.

Answer: 0.7497

Step-by-step explanation:

Mean = 9

sd = 0.6

n = 4

P(4 babies will be between 8.4 and 9.6 pounds)

P(8.4 ≤ X ≤ 9.6)

Standard error of the sample (S. E) :

S. E = sd/√n

= 0.6 /√4

= 0.6/2

= 0.3

P(8.4 ≤ X ≤ 9.6)= ((P(8.4 - 9) / 0.3) ≤ X ≤ (9.6 - 9)/0.3)

P(8.4 ≤ X ≤ 9.6) = P(-2 ≤ X ≤ 2)

P(Z ≤ 2) - P(Z < - 2)

0.9772 - 0.2275 = 0.7497

The curve representing the relationship includes the point

The growth factor is

An earthquake with an energy level of has a magnitude of

The equation 'M = 0.6666 log x - 3.2' describes the relationship between the energy produced by an earthquake (x) and its **resulting magnitude** (M). The 0.6666 in the formula is the growth factor. To get a magnitude for a specific energy level, we plug the energy value into the formula, and solve.

The equation given represents the relationship between the magnitude of an earthquake (M) and the energy it produces (x), with M being the earthquake's magnitude and x being the energy produced by the earthquake. This equation is a logarithmic model with a base of 10 (without the base explicitly stated, we assume it to be 10).

**The curve representing the relationship includes the point**: To identify a point, we need a specific x-value for the energy level. For instance, for x=1000, we can plug it into the equation to get the magnitude M = 0.6666 log(1000) - 3.2.**The growth factor is**: In this context, the growth factor refers to the constant 0.6666 which is multiplied by the logarithm. This factor impacts the rate at which the magnitude of the earthquake grows for a given increase in energy.**An earthquake with an energy level of**(an x-value should be inserted here)**has a magnitude of**: We would again plug the energy value (x-value) into the formula, compute the expression to determine the corresponding magnitude.

**Step-by-step explanation:**

**Answer:**

B

**Step-by-step explanation:**

I assume you're referring to the product,

Recall the change-of-base identity:

where *c* > 0 and *c* ≠ 1. This means the product is equivalent to

and it telescopes in the sense that the numerator and denominator of any two consecutive terms cancel with one another. The above then simplifies to

The **percentage** change in the price is 41.42%.

Percentage is defined as a given part or amount in every hundred. It is a **fraction** with 100 as the denominator and is represented by the symbol "%".

Given that, a price of £70 is increased to £99.

Now, the difference is 99-70=29

Percentage increase is 29/70 ×100

= 0.4142×100

= 41.42%

Therefore, the **percentage** change in the price is 41.42%.

**Answer: Your answer is 41.43%**

**To calculate, it is simply (99-70)/70 x 100**

**which is equal to 41.43%**

**Step-by-step explanation:**

Answer:

50%

Step-by-step explanation:

Let :

Winter = W

Summer = S

P(W) = 0.85

P(S) = 0.65

Recall:

P(W u S) = p(W) + p(S) - p(W n S)

Since, none of them did not like both seasons, P(W u S) = 1

Hence,

1 = 0.85 + 0.65 - p(both)

p(both) = 0.85 + 0.65 - 1

p(both) = 1.50 - 1

p(both) = 0.5

Hence percentage who like both = 0.5 * 100% = 50%
