BRAINLIEST please if this helped!Daniel has a bag that contains pineapple chews, apple chews, and watermelon chews. He performs an experiment. Daniel randomly removes a chew from the bag, records the result, and returns the chew to the bag. Daniel performs the experiment 51 times. The results are shown below:
A pineapple chew was selected 21 times.
A apple chew was selected 12 times.
A watermelon chew was selected 18 times.
Based on these results, express the probability that the next chew Daniel removes from the bag will be a flavor other than watermelon as a decimal to the nearest hundredth.
The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is 0.65
How to determine the probability?The distribution of the fruits is given as:
Pineapple = 21Apple = 12Watermelon = 18The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is:
P = (Apple + Pineapple)/Total
This gives
P = (12 + 21)/(21 + 12 + 18)
Evaluate
P = 0.65
Hence, the probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is 0.65

The mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.
How to measure the weight?Weight measurement is the measurement of the heaviness of a object. The units of weight measurement are pounds, grams, kilograms etc.
There is total 1000 grams in one kilogram of weight measurement.
Lynn filled each of three bags with 2 kilograms, 450 grams of sand. There is total 1000 grams in one kilogram of weight measurement. Thus, the kilogram in 450 grams is,
[tex]x=\dfrac{450}{1000}\\x=0.45\rm\; kg[/tex]
Thus, weight in one bag is,
[tex]W=2+0.45\\W=2.45\rm\; kg[/tex]
The weight in two bags is,
[tex]2W=2.45+2.45\\2W=4.9\rm\; kg[/tex]
The weight of 4.9 kg is less than the 5 kilogram..
Thus, the mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.

Answer:
1/6 or 0.167
Step-by-step explanation:
First understand that 4 x 1/4 is equal to 1, then replace it in the equation
1 - 5/6
Turn the whole number into a fraction that can be computed
6/6 - 5/6
Solve the equation
6/6 - 5/6 = 1/6
If you need it as a decimal enter it in a calculator and get
0.16666666667
Since the 6 is repeating you can just round that to

How many x intercepts does the polynomial function y=(x-8)(x+3)^2
Answer:
The answer is 2 x-intercepts
Step-by-step explanation:
To determine the x-intercepts we set y to zero and solve for x:
y=0
(x-8)(x+3)^2=0
The product of 2 factors is 0 means that one of them must be 0:
x-8=0 ⇒ x=8 →first x-intercept
or (x+3)^2=0 ⇒ x+3=0 ⇒ x=-3 →second x-intercept
Therefore the polynomial function two roots, so it has two x-intercepts x=8 and x=-3

Use either elimination or substitution.
y = x - 4
x + y = 6
Answer:
Since x = 3, y = 1 is the solution of
x – 4y + p = 0 …………….. (i)
2x + y – q – 2 = 0 …………… (ii)
So, x = 3, y = 1 must satisfy both (i) and (ii).
⇒ 3 – 4(1) + p = 0 ⇒ p = 1.
and 2(3) + (1) – q – 2 = 0 ⇒ q = 5
Since, 1 = – 4 + 5
∴ p = 1 = – 4 + 5
= q – 4
⇒ p = q – 4

Find the slope of the tangent to the curve [tex]y=3+4 x^{2}-2 x^{3}[/tex] at the point where [tex]x=a\text{.}[/tex]
Derivatives:The derivative of a function can be determined using different rules and formulations. One of the important rules here is the power rule. Power rule is used to differentiate functions in the form of [tex]f(x) = x^n[/tex].
[tex]\; \dfrac{d}{dx} (x^n) = nx^{n-1}[/tex]
Explanation:We are supposed to find the slope of the tangent to the curve [tex]y=3+4 x^{2}-2 x^{3}[/tex] at the point where [tex]x=a[/tex].
[tex]\implies \dfrac{d}{dx}(3+4x^2-2x^3)[/tex]
[tex]\implies \dfrac{d}{dx}(0+4(2x^{2-1})-2(3x^{3-1})[/tex]
[tex]\implies \dfrac{d}{dx}(0+4(2x)-2(3x^2)[/tex]
[tex]\implies \dfrac{d}{dx}(8x-6x^2[/tex]
Now plugging [tex]x=a[/tex] in the above equation, we obtain the following results:
[tex]\implies \boxed{8a -6a^2}[/tex]

What is the compliment of an angle that measures 2x degrees?
Answer:
(90 - 2x)°
Step-by-step explanation:
complimentary angles sum to 90° , then
the compliment of 2x° is (90 - 2x)°
Answer:
(90 - 2x)°
Step-by-step explanation:
We say that two angles are complementary if their measures add up to 90°
The complement of an angle that measures 2x is the angle of measure
(90 - 2x)°
because 2x + (90-2x) = 90

Differentiate x and y with respect to t :
[tex]x = e^{\sec(2t)} \implies \dfrac{dx}{dt} = e^{\sec(2t)} \dfrac{d(\sec(2t))}{dx} = 2\sec(2t)\tan(2t) e^{\sec(2t)}[/tex]
[tex]y = e^{\tan(2t)} \implies \dfrac{dy}{dt} = e^{\tan(2t)} \dfrac{d(\tan(2t))}{dx} = 2\sec^2(2t) e^{\tan(2t)}[/tex]
By the chain rule,
[tex]\dfrac{dy}{dx} = \dfrac{dy}{dt} \times \dfrac{dt}{dx} = \dfrac{\frac{dy}{dt}}{\frac{dx}{dt}}[/tex]
Then
[tex]\dfrac{dy}{dx} = \dfrac{2\sec^2(2t) e^{\tan(2t)}}{2\sec(2t)\tan(2t) e^{\sec(2t)}} = \dfrac{\sec(2t) e^{\tan(2t)}}{\tan(2t) e^{\sec(2t)}} =\dfrac{y \sec(2t)}{x\tan(2t)}[/tex]
and we have
[tex]\log(x) = \sec(2t)[/tex]
[tex]\log(y) = \tan(2t)[/tex]

Complete the equation for ⊙A.
A 2-dimensional graph with an x-axis and a y-axis is given. A circle is passing through the co-ordinates (-4,1), (-1,-2), (-4, -5) and (-7,-2) respectively. A point A which is the mid-point of the circle has co-ordinates (-4,-2).
The general equation of a circle is (x-h)²+(y-k)² = r². The equation of circle A is (x+4)²+(y+2)²=9.
What is the equation of a circle?The general equation of a circle is given as,
(x-h)²+(y-k)² = r²
Where (h,k) is the coordinate of the centre of the circle, and r is the radius of the circle,
Given that the four points that lie on the circle are (-4,1), (-1,-2), (-4, -5) and (-7,-2), and also the centre of the circle is at (-4,-2). Therefore, the radius of the circle will be the distance between the centre of the circle and any point lying on the circle.
[tex]\rm \text{Radius of the circle} = \sqrt{[(-4)-(-4)]^2+[(-2)-(1)]^2}\\\\\text{Radius of the circle} = \sqrt{(0)^2+(-3)^2}\\\\\text{Radius of the circle} = 3\ units[/tex]
Since the coordinate of the centre point of the circle is (-4,-2), while the radius of the circle is 3 units, therefore, the equation of the circle can be written as,
[tex][x-(-4)]^2+[y-(-2)]^2 = 3^2\\\\(x+4)^2+(y+2)^2 = 3^2\\\\(x+4)^2+(y+2)^2 = 9[/tex]
Hence, the equation of circle A is (x+4)²+(y+2)²=9.
