If has a decimal approximation of 3.4, then is between which two integers? In your final answer, include all calculations.

olganol [36]

Answer: It is between 3 and 4.

Step-by-step explanation:

Integers are whole numbers and its opposite, for example, -5,-4,-3,-2,-1, 0, 1,2,3,4, 5 ,....

Meaning that 3.4 is not an integer so it fall between two integers and those integers has to be positive because 3.4 is a positive number.

3.4 is slightly greater than 3 but is less than 4.

Meaning that 3.4 is between the integers 3 and 4.

A company services home air conditioners. It is known that times for service calls follow a normal distribution with a mean of 7

SCORPION-xisa [38]

Answer:

The probability that exactly eight of them take more than 93.6 minutes is 5.6015 $\times 10^{-6}$ .

Step-by-step explanation:

We are given that it is known that times for service calls follow a normal distribution with a mean of 75 minutes and a standard deviation of 15 minutes.

A random sample of twelve service calls is taken.

So, firstly we will find the probability that service calls take more than 93.6 minutes.

Let X = times for service calls.

So, X ~ Normal( $\mu=75,\sigma^{2} =15^{2}$ )

The z-score probability distribution for the normal distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean time = 75 minutes

$\sigma$ = standard deviation = 15 minutes

Now, the probability that service calls take more than 93.6 minutes is given by = P(X > 93.6 minutes)

P(X > 93.6 min) = P( $\frac{X-\mu}{\sigma}$ > $\frac{93.6-75}{15}$ ) = P(Z > 1.24) = 1 - P(Z $\leq$ 1.24)

= 1 - 0.8925 = 0.1075

The above probability is calculated by looking at the value of x = 1.24 in the z table which has an area of 0.8925.

Now, we will use the binomial distribution to find the probability that exactly eight of them take more than 93.6 minutes, that is;

$P(Y = y) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r} ; y = 0,1,2,3,.........$

where, n = number of trials (samples) taken = 12 service calls

r = number of success = exactly 8

p = probability of success which in our question is probability that

it takes more than 93.6 minutes, i.e. p = 0.1075.

Let Y = Number of service calls which takes more than 93.6 minutes

So, Y ~ Binom(n = 12, p = 0.1075)

Now, the probability that exactly eight of them take more than 93.6 minutes is given by = P(Y = 8)

P(Y = 8) = $\binom{12}{8}\times 0.1075^{8} \times (1-0.1075)^{12-8}$

= $495 \times 0.1075^{8} \times 0.8925^{4}$

= 5.6015 $\times 10^{-6}$ .

Express the polynomial below by nesting. f(x)=4x³+3x²+2x-4

BabaBlast [244]

Answer:

$f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Step-by-step explanation:

Considering the polynomial

$f(x)=4x^{3} +3x^{2} +2x-4$

Expressing the polynomial by nesting

So,

$f(x)=4x^{3} +3x^{2} +2x-4$

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

$4x+3$

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

$(4x+3)x+2$

Step 3) Repeating the previous step until all terms are within the equation.

So,

$((4x+3)x+2)x-4$

Therefore, $f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Keywords: polynomial, nesting form
