Answer:

              [tex]\bold{y=-\frac12x}[/tex]

Step-by-step explanation:

Slope-intercept form:   y = mx + b

The line intersect Y-axis at y=0 so b = 0

The line passses through points (0, 0) and (2, -1), so the slope:

[tex]m=\dfrac{-1-0}{2-0}=-\dfrac12[/tex]

Therefore the equation:

                                        [tex]y=-\frac12x+0\\\\y=-\frac12x[/tex]

Step-by-step explanation:

Since PT = 2PM and AR = 2AD,

The midsegment MD must be the average of PA and TR:

Therefore we have

2(20x + 4) = 10 + (34x + 16)

=> 40x + 8 = 34x + 26

=> 6x = 18

=> x = 3

Hence length of MD

= 40(3) + 8 = 128.

Answer:

A, D, and F

Step-by-step explanation:

First off, we're not given the hypotenuse's length, so let's use the Pythagorean Theorem to find it:

[tex]1^2+3^2=c^2\\1+9=c^2\\10=c^2\\c=\sqrt{10}[/tex]

With that, we can refer to SOH-CAH-TOA to help us find sine, cosine, and tangent:

SOH (Sine = Opposite/Hypotenuse)

[tex]\sin{\theta}=1/\sqrt{10}=\sqrt{10}/10[/tex]

CAH (Cosine = Adjacent/Hypotenuse)

[tex]\cos{\theta}=3/\sqrt{10}=3\sqrt{10}/10[/tex]

TOA (Tangent = Opposite/Adjacent)

[tex]\tan{\theta}=1/3[/tex]

From this, we can see that A matches up with sine, and we can eliminate B and C.

Cosecant, secant, and cotangent are all reciprocals of the three basic trig ratios:

[tex]\csc{\theta}=1/\sin{\theta}=\sqrt{10}\\\sec{\theta}=1/\cos{\theta}=\sqrt{10}/3\\\cot{\theta}=1/\tan{\theta}=3[/tex]

D matches with cosecant, and F matches with cotangent, so the correct trig rations for θ are A, D, and F.

Answer:

Option C is correct option.

Step-by-step explanation:

We need to select the statement that does not correctly use probability to describe an  event.

Probability

Whenever we need to find probability of something it lies between 0 and 1.

So, if any item has probability greater than 1 then it is incorrectly described.

Now, looking at the options:

A. The probability of a storm tomorrow is 60%.

Here probability is 0.6 (60/100 = 0.6) so it is used correctly

B. The probability of finding a matching pair of socks is 1/3

 Here probability is 0.33 (1/3 = 0.33) so it is used correctly

C. The probability of taking a good class picture is 1.3.

 Here probability is 1.3 but probability can be between 0 and 1. So here it is not used correctly.

D. The probability that the dog will catch the ball is 0.99.​

Here probability is 0.99 so it is used correctly

Therefore Option C is correct option.

Answer:

C. The probability of taking a good class picture is 1.3

Answer:

The area of the wall is 435 square foot.

Step-by-step explanation:

a) Data and Calculations:

One side of the wall (height) = 14 1/2 foot = 14.5 foot

The second side of the wall (length) = 30 foot

The area of the wall = height * length

= 14.5 * 30

= 435 square foot

b) The area of a wall is usually obtained by Height x Length.  It uses the same standard formula of (Length) x (Width) for calculating the area of any surface, only that this time, the width changes to height because of the nature of the wall.

Answer:

(-11,-4) and (-5,-7)

Step-by-step explanation:

the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.

Apply the rule to the 1st question by plugging in the coordinates:

(x,y)→(x−7,y+2)

(−4,−6)→((-4)−7,(-6)+2)

(−4,−6)→(-11,-4)

Let's use the same process for the 2nd question:

(x,y)→(x−7,y+2)

(2,−9)→((2)−7,(-9)+2)

(2,−9)→(-5,-7)

Answer: 0.5 < x < 16.5.

Step-by-step explanation:

Given: Two sides of triangle: 8.0 units and 8.5 units

Measure of third side = x

According to the triangle's inequality,

If x is the third side, then

x < 8+8.5   [Using (i)]

i.e. x< 16.5  

Also, x > 8.5-8   [Using (ii)]

i.e. x> 0.5

Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.

Answer:

y = 48, x = 11

Step-by-step explanation:

6x = 3x + 33

3x = 33

x = 11

6x + 3x + 33 + y = 180

66 + 33 + 33 + y = 180

66 + 66 + y = 180

132 + y = 180

y = 180 - 132

y = 48

Answer:

C x=40, y=30

Step-by-step explanation:

Remember the opposite side of parallelogram is the same

so angle C and angle A is the same.

3x=120

divide both sides by 3 and you get 40

All parallelogram equal to 180 degrees so to find y

180=2y+120

-2y=120-180

-2y=-60                   negative divide negative is positive.

y=30

Answer:

8.5

Step-by-step explanation:

Given that;

The longest side of an acute isosceles triangle = 12 centimeters

Since the two remaining sides are congruent, then they both have the same length ;

Let the length of the two remaining sides = 2x,

The length of each side :

Length of longest side / sqrt(2)

x = 12 /sqrt(2)

x = 12 / 1.4142135

x =8.4852813

x = 8.5

Answer:

166

Step-by-step explanation:

Answer:

$1.66x100 would be 166 or $166.

Step-by-step explanation:

Since you are multiplying by 100, you could move the decimal point to the right twice which would give you $166, or you could multiply normally.

Correct on Edge 2021

The probability of success (p = 0.8) in each trial remains constant.

The trials are independent. This implies that the outcome from one trial has no effect on the outcome to be obtained from any other trial.

Each trial results in only two possible outcomes, labeled as the success ( Blue ) and failure ( Not blue ).

The experiment is performed a fixed number of times (n=12).

The X is a binomial random variable is 0.1329.

Given that,

An online spinner has two colored regions--blue and yellow.

According to the website, the probability that the spinner lands in the blue region on any spin is 0.80.

Assume for now that this claim is correct. Suppose we spin the spinner 12 times.

We have to determine,

X is a binomial random variable.​

According to the question,

Therefore,

Number of trials: n = 12

Probability of success: p = 0.8

Let, x be the number of successes ( Blue ) in 12 trials.

The probability function of X:

[tex]P(X=x) = \ ^nC_x \times P^x \times (1-p)^{n-x}[/tex]

To find P(X = 8). Interpret this value in context.

At x = 8

[tex]P(X=8) = \ ^{12}C_2 \times (0.8)^{8} \times (1-0.08)^{12-8}\\\\P(X=8) = \dfrac{12!}{10!\ 2!} \times (0.8)^8\times (0.92)^4\\\\P(X=8) = 495 \times (0.167) \times (0.0016)\\\\P(X=8) = 0.1329[/tex]

Hence, The X is a binomial random variable is 0.1329.

No, (12, 14) this is not a solution of the inequality

Step-by-step explanation:

(x, y)

x = 12 2-by-8 boards

y = 14 4-by-4 boards

(12, 14)

8x + 12y <= $250

This means that a 2-by-8 board cost $8 each, while a 4-by-4 board cost $12 each.

8(12) + 12(14) <= 250
