Answer:

y = (1/2)(x) + 1/2

Step-by-step explanation:

The x-intercept is (-1, 0) and the y-intercept appears to be (0, 1/2).

As we go from the x-intercept to the y-intercept, x increases by 1 and y increases by 1/2.  Thus, the slope of the line is m = rise / run = 1/2.

Knowing that m = 1/2 and b = (0, 1/2), we can write the equation of this line in slope-intercept form as

y = (1/2)(x) + 1/2

An unfair coin has a probability of coming up heads of 0.65. The coin is flipped 50 times. What is the probability it will come
Lady bird [3.3K]

Answer: the probability it will come up heads 25 or fewer times is 0.019

Step-by-step explanation:

Given that;

n = 50

p = 0.65

so, q = 1 - p = 0.35

np = 50 × 0.65 = 32.5 ≥ 10

nq = 50 × 0.35 = 17.5 ≥ 10

so, we need to use Normal Approximation for the Binomial Distribution

μ = np = 50 × 0.65 = 32.5

σ = √(npq) = √( 50 × 0.65 × 0.35 ) = 3.3726

now, the probability that it will come up heads 25 or few times will be;

⇒ P( x≤25)

{using continuity correction}

⇒ P[ z < (25.5 - 32.5)/3.3726 ]

⇒ P[ z < -2.0755 ]

using z-table

= 0.01923 ≈ 0.019  { 3 decimal places}

Therefore the probability it will come up heads 25 or fewer times is 0.019

Help please...........
attashe74 [19]

Given the volume of Wesley's cube = 8 cubic centimeters.

We know the formula for volume of cube is given as follows :-

Volume of cube = (side) x (side) x (side)

8 = (side)³

side = \sqrt[3]{8} =\sqrt[3]{2*2*2} =2

Hence, Wesley's cube dimensions are 2 centimeters.

The square must have side length as 2 centimeters.

If smallest square G represents 1 centimeters, then clearly it is H = 2 centimeters.

So, square H is the final answer.

Write a whole number that, when rounded to the nearest hundred, is 700.
omeli [17]
A number that would be rounded to 700 would be 695. if i'm wanting to round to the nearest hundred then i would look at the number behind the number i'm rounding so i would look at 9. 9 is 5 or more so we round up to 700.
