Step-by-step explanation:

The square root of 40 is about 6.32, so this number belongs between 6 and 7 on a number line.

Answer:

number 3 will be right

Step-by-step explanation:

The correct statement is : y=2x+9

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: The linear equation is y=2x-4

Now the equation y=2x+9

equating both linear equations are

2x-4=2x+9

-4=9 which is not possible

Thus the incorrect equation that gives no solution is y=2x+9

Sample proportion, [tex]$(\hat p_1)=\frac{x_1}{n_1}$[/tex]

                                        [tex]$=\frac{294}{388}$[/tex]

                                       = 0.0671

For 95 % CI, z = 1.96

The confidence interval for the population proportion,

[tex]$p_1-p_2=(\hat p_1-\hat p_2)\pm z \left\{\sqrt{\frac{\hat p_1 \times (1- \hat p_1)}{n_1}+\frac{\hat p_2 \times (1- \hat p_2)}{n_2}}\right\}$[/tex]

Answer:

The expected number of ducks that will be hit is 4.

Step-by-step explanation:

For each hunter, there are only two possible outcomes. Either they hit a duck, or they do not. The probability of a hunter hitting a ducks is independent of any other hunter. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

A group of 10 hunters wait for ducks to fly by.

This means that [tex]n = 10[/tex]

Each hunter independently hits his target with probability 0.4

This means that [tex]p = 0.4[/tex]

What is the expected number of ducks that will be hit?

[tex]E(X) = np = 10*0.4 = 4[/tex]

The expected number of ducks that will be hit is 4.

Answer:

Step-by-step explanation:

We can rewrite the equation to standard form to see the center and semi-axis lengths.

  16x^2 -128x +y^2 +3y = -256

  16(x^2 -8x +16) +(y^2 +3y +2.25) = -256 +256 +2.25

  16(x -4)^2 +(y +1.5)^2 = 9/4 . . . . . write as squares

  (x -4)^2/(9/64) +(y +1.5)^2/(9/4) = 1 . . . . divide by 9/4

  ((x -4)/0.375)^2 +((y +1.5)/1.5)^2 = 1 . . . . put in useful form

In this form, we have ...

  ((x -h)/a)^2 +((y -k)/b)^2 = 1

where (h, k) is the center, 2a is the length of the axis in the x-direction, and 2b is the length of the axis in the y-direction. The required tangents are ...

  x = h±a

  y = k±b

For the given ellipse, the tangent lines are ...

Answer:

330 cubic feet

Step-by-step explanation:

The formula for Volume is L (length) x W (width)  x H (Hight)

So all we have to do is multiply the numbers for each floor and then add them together.

5 x 3 = 15 15 x 6 = 90

6 x 5 = 30 30 x 8 = 240

240 + 90 = 330

Now add you cubic feet since volume is cubed.

330 cubed feet

Thus, your answer is 330 cubed feet.

[tex] R = \frac {3ST}{2S + T} [/tex]

Step-by-step explanation:

Given the equation;

[tex] \frac {3}{R} - \frac {1}{S} = \frac {2}{T} [/tex]

Rearranging the equation, we have;

[tex] \frac {3}{R} = \frac {2}{T} + \frac {1}{S} [/tex]

Lowest common multiple (LCM) of S and T is ST.

[tex] \frac {3}{R} = \frac {2S + T}{ST} [/tex]

Cross-multiplying, we have;

[tex] 3ST = R(2S + T) [/tex]

Making R, the subject of formula;

Answer:

100 km/hr

Step-by-step explanation:

11:00 a.m. less 7:30 a.m. works out to 3:30 hours (3 hours 30 minutes).

Then the speed of the bus was

 350 km

--------------- = 100 km/hr, or about 62.5 mph

  3.5 hrs

Answer:

100 km/hr

Step-by-step explanation:

Givens

T = 11:00 - 7:30

T = 3  hours 30 minutes

T = 3 1/2 hours

t = 3.5 hours

d = 350 km

Formula

d = v * t

Solution

350 km = v * 3.5           Divide by 3.5

350 km / 3.5 hours = v

350 / 3.5 = v

v = 100 km/hour

Step-by-step explanation:

Answer:

Alex (0.95), Tonya (0.90), Wilson (0.87), Octavia (0.80)

Step-by-step explanation:

To solve this, we have to convert all of the scores into either a decimal or a fraction. In this case, I will be solving all of them into decimals since it is easier.

Alex: 0.95

Octavia: 16/20 = 0.80

Tonya: 9/10 = 0.90

Wilson: 0.87

Therefore, we can order these from greatest score to least score.

Alex (0.95), Tonya (0.90), Wilson (0.87), Octavia (0.80)

Answer:  1

Step-by-step explanation:

Experimental probability is the actual result you get from an experement.

Theoretical probability is the change that you will get that result.

(for example: flipping a coin, the Theoretical probability is 50/50 but after testing the Experimental probability might be 47/53)

therefore,

1/6 is the Theoretical probability because you are using a six-sided number cube.

for the Theoretical probability and the Experimental probability to be the same, the fraction of the roll must equal 1/6.

1/6 equals 8/48.

therefore, since the numbers 1 and 6 were both rolled 8 times out of 48 they are consistant with the Theoretical probability of 1/6.

6 is not one of the answer choices listed so 1 must be your answer.
