Step-by-step explanation:

We just need to graph each pair of values, because each pair represents one point on the scatter plot.

Basically, the points we are gonna draw are

(1, 1300)

(2, 2500)

(3, 3600)

(4, 4000)

(5, 2200)

(6, 1800)

(7, 3200)

(8, 900)

The image attached shows all these points draw on the scatter plot. Just remember that the first value of a pair belong to the horizontal axis, and each second value belongs to the vertical axis.

) Determine the probability that a bit string of length 10 contains exactly 4 or 5 ones.
yanalaym [24]

Answer: 0.4512

Step-by-step explanation:

A bit string is sequence of bits (it only contains 0 and 1).

We assume that the  0 and 1 area equally likely to any place.

i.e. P(0)= P(1)= \dfrac{1}{2}

The length of bits : n = 10

Let X = Number of getting ones.

Then , X \sim Bin(n=10,\ p=\dfrac{1}{2})

Binomial distribution formula : P(X=x)=^nC_x p^x q^{n-x} , where p= probability of getting success in each event and q= probability of getting failure in each event.

Here , p=q=\dfrac{1}{2}

Then ,The probability that a bit string of length 10 contains exactly 4 or 5 ones.

P(X= 4\ or\ 5)=P(x=4)+P(x=5)\\\\=^{10}C_4(\dfrac{1}{2})^{10}+^{10}C_4(\dfrac{1}{2})^{10}

=\dfrac{10!}{4!6!}(\dfrac{1}{2})^{10}+\dfrac{10!}{5!5!}(\dfrac{1}{2})^{10}

=(\dfrac{1}{2})^{10}(\dfrac{10!}{4!6!}+\dfrac{10!}{5!5!})

=(\dfrac{1}{2})^{10}(210+252)

=(0.0009765625)(462)

=0.451171875\approx0.4512

Hence, the  probability that a bit string of length 10 contains exactly 4 or 5 ones is 0.4512.

-7- 2x² - 6 = −2x² + 1<br> First Step:<br> 13- 2x² = 2x² + 1<br> What property is this
lorasvet [3.4K]

Answer:

Combine like terms, although the provided answer is missing a "-" sign in front of the "13."  

Step-by-step explanation:

Combine like terms.  The -7 and -6 can be added to produce -13.

The correct result is <u>-</u>13 - 2x^2 = <u>-</u>2x^2 + 1  [Not _13- 2x² = _2x² + 1

ELEN [110]

Answer:

B) 0=(2x+3)(x-1)

Step-by-step explanation:

factor the equation f(x) = 2x² + x - 3

=> f(x) = (2x + 3)(x - 1)
