Hi there

I think I may have the answer for you!

<u>Answer:</u>

Use the Remainder Theorem to find the remainder: (16x^4 – 8x^3 – 4x + 1) ÷ (2x + 1)
vodka [1.7K]

Answer:

5

Step-by-step explanation:

This illustrates the Remainder Theorem. If a polynomial f(x) is divided by x−a , the remainder is the constant f(a) , and f(x)=q(x)⋅(x−a)+f(a) , where q(x) is a polynomial with degree one less than the degree of f(x) . Synthetic division is a simpler process for dividing a polynomial by a binomial.

Please help me with this
ExtremeBDS [4]

Answer:

Bottom left

Step-by-step explanation:

For it to be scalene, all 3 sides must be of different length, so cross off D. Acute means all angles are less then 90°, so cross off the top 2.

A​ person's blood pressure is monitored by taking 4 readings daily. The probability distribution of his reading had a mean of 13
ss7ja [257]

Answer:

a) Mean = 133, Standard deviation = 2.5

b) Normal distribution

c) 0.0026

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 4

Mean = 133

Standard deviation = 5

a) Mean and the standard deviation of the sampling distribution of the sample mean for the four observations each day.

The sampling distribution has a mean equal to the population mean

\bar{x} = \mu = 133

The standard deviation of the sampling distribution is given by:

\sigma_s = \dfrac{\sigma}{\sqrt{n}} = \dfrac{5}{\sqrt{4}} = 2.5

b) Shape of the sampling​ distribution

Central limit theorem:

When a large sample is drawn from a normal distribution, then the distribution of sample means approaches a normal distribution.

Since the distribution is normal,  the sampling distribution of the sample mean will be bell shaped and follow a normal distribution.

c) P(sample mean exceeds 140)

P( x > 140) = P( z > \displaystyle\frac{140 - 133}{2.5}) = P(z > 2.8)

= 1 - P(z \leq 2.8)

Calculation the value from standard normal z table, we have,  

P(x > 140) = 1 - 0.9974 = 0.0026

0.0026 is the probability that the sample mean exceeds 140.
