Answer:

5/11

Step-by-step explanation:

Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.

So there are

The probability of picking either of these colors is simply the sum of their probabilities.

Answer:

0.488

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Here, n = 3 and p = 0.2.

The complement of at least 1 is at most 0.

P(r ≥ 1) = 1 − P(r = 0)

P(r ≥ 1) = 1 − ₃C₀ (0.2)⁰ (0.8)³⁻⁰

P(r ≥ 1) = 1 − (0.8)³

P(r ≥ 1) = 0.488

Answer:

18%

Step-by-step explanation:

There are 64 students with brown eyes and black hair, and 9 students with blue eyes and black hair. A total of 303 students were surveyed, so to find the percentage you would put the number of students with that trait over the total number of students surveyed. 64/303 = 21.1221%, and 9/303 = 2.9702%. 21.1221 - 2.9702 = 18.1519. When you round that to the nearest whole number, you get 18%. Therefore, the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18%.

18%

Answer:

See attachment

Step-by-step explanation:

If x + y = 180°, the remaining angles can be labelled as illustrated in the diagram provided in the attachment below.

To properly label the diagram so that x° + y° = 180°, you must bear in mind or recall relation between angles formed when two parallel lines are cut across by a transversal line.

x° would be congruent to any angle that is either corresponding or vertical to it.

That is, for the angles labelled x°, such an angle is either corresponding to the given x° or it is vertically opposite to it.

Consequently, where the angle labelled y° forms a linear pair with x°. Linear pair of angles add up to give 180°.

Step-by-step explanation:

To find the equation of line  [tex]y=mx+b[/tex]  through (3, 7) and (5, 11) we first need to find the slope of line and then y-intercept.

[tex]\mathrm{Slope=m=\frac{y_2-y_1}{x_2-x_1}=\frac{11-7}{5-3}=2}[/tex]

Answer:

Step-by-step explanation:

Answer:

-2 (6x - y) = -12x + 2y

Step-by-step explanation:

By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y

Answer:

Step-by-step explanation:

Rate X Time = distance

Therefore:

    r (rate) X 5 (hours) = 600 (distance)

    r = 600/5

    r = 120 miles per hour

    The rate of speed of the jet is 120 mph.

Then, to find out the distance flown in 13 hours:

    120 (rate) X 13 (time) = d (distance)

    120 X 13 = d

    1560 = d

    The distance flown in 13 hours is 1560 miles.

Step-by-step explanation:

The addition is one of the four fundamental mathematical operations. Blair's bank balance after spending at the grocery store is -$70.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that Blair's bank account was overdrawn by $40. Therefore, we can write her balance before spending at the grocery store as,

Blair's bank balance before spending at the grocery store = - $40

Now, Blair spent $30 at the grocery store. Therefore, she further takes $30 from her account. Thus, we can write Blair's bank balance after spending at the grocery store as,

Blair's bank balance after spending at the grocery store

= Blair's bank balance before spending at the grocery store + Spending

= -$40 + (-$30)

= -$40 - $30

= -$70

Hence, Blair's bank balance after spending at the grocery store is -$70.

Answer:

[tex](-4, -1)[/tex]

Step-by-step explanation:

[tex]6x-y=-23[/tex]

Add y to both sides:

[tex]6x-y+y=-23+y\\6x=-23+y[/tex]

Divide both sides by 6:

[tex]\frac{6x}{6}=-\frac{23}{6}+\frac{y}{6}\\x=\frac{-23+y}{6}[/tex]

Substitute this into the second equation given:

[tex]2*\frac{-23+y}{6}+5y=-13[/tex]

[tex]\frac{-23+16y}{3}=-13[/tex]

Multiply both sides by 3:

[tex]-23+16y=-39[/tex]

Add 23 to both sides:

[tex]-23+16y+23=-39+23\\16y=-16[/tex]

Divide both sides by 16:

[tex]\frac{16y}{16}=\frac{-16}{16}\\y=-1[/tex]

We know that [tex]x=\frac{-23+y}{6}[/tex].

Thus, [tex]x=\frac{-23-1}{6}[/tex]

[tex]x=-4[/tex]

[tex](x, y) = (-4, -1)[/tex]

Solution: First option

Step-by-step explanation:

An increase in demand and a decrease in supply will cause an increase in the equilibrium price, but the effect on quantity is unclear.

Reasoning: For any quantity, the 'buyers' places a higher value on the goods, so the 'manufactures' must place higher values in order to distribute the good. Thus the price increases, but the output depends on the size of the two factors and which dominates, (1) pricing, (2) goods.

Answer:

Jennie earned $300

Step-by-step explanation:

We are already given the amount of time that she works and the rate. We just need to multiply the time by the corresponding rate. She worked 22 regular hours and gets $10 for each one. That means she earned $220 just from the regular hours.

Now we need to add the overtime hours. She worked 4 hours and made $20 for each one. In total, that's $80.

220+80=300

Answer:

It's 0.61

Step-by-step explanation:

I graphed the equation and got 0.61 on the x axis when the y value was 1.24

The missing x-coordinate is 9.5. The correct answer is option D.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

The given function [tex]y = 2 -\sqrt{x+1}[/tex] and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.

[tex]y = 2 -\sqrt{x+1}[/tex]

[tex]-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}[/tex]

Squaring on both sides.

[tex](-3.24)^2 = (\sqrt{x+1})^2[/tex]

10.5 = x + 1

x = 9.5

Hence, the correct option is D.
