Kaye will compute for the area of a circle using the formula A=π×r2.If given is the diameter of a circle , what should be computed first?

Answers

Answer:

Find the radius.

Step-by-step explanation:

The task is to solve for area of a circle, and you are given the diameter.

The formula for area is :

Area of a circle = π × (radius)²

In this formula, there is only one input value, and that is the radius.

To find the radius, you must know the relation :

Radius x 2 = Diameter

Hence, the radius must be computed first and foremost.

For the the axis of symmetrythe vertex and the yintercept y = x ^ 2 + 16x + 24

Answers

Answer: D (bottom option)

Axis of Symmetry: x = -8

Vertex: (-8, -40)

Y-Intercept: 24

Step-by-step explanation:

Start by putting the equation into vertex form, which you can do by completing the square. This means the equation will in the form [tex]y=a(x-h)^2+k[/tex].

Once you've done that, you'll get [tex]y=(x+8)^2-40[/tex]. This means that h = -8 and k = -40, so the vertex is (-8, -40) because vertex form is (h, k).

The axis of symmetry is x = -8, because the axis of symmetry is x = h.

When putting it into a graphing calculator, you have to find the middle “line”, in this example the axis of symmetry is -8.

The Axis of Symmetry is -8

Find the probability of each event.

A fair coin is flipped ten times. What is
the probability of the coin landing tails up
at least nine times?

Answers

Using the binomial distribution, it is found that there is a 0.0108 = 1.08% probability of the coin landing tails up at least nine times.

What is the binomial distribution formula?

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.

In this problem:

The coin is fair, hence p = 0.5.The coin is tossed 10 times, hence n = 10.

The probability that is lands tails up at least nine times is given by:

[tex]P(X \geq 9) = P(X = 9) + P(X = 10)[/tex]

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 9) = C_{10,9}.(0.5)^{9}.(0.5)^{1} = 0.0098[/tex]

[tex]P(X = 10) = C_{10,10}.(0.5)^{10}.(0.5)^{0} = 0.001[/tex]

Hence:

[tex]P(X \geq 9) = P(X = 9) + P(X = 10) = 0.0098 + 0.001 = 0.0108[/tex]

0.0108 = 1.08% probability of the coin landing tails up at least nine times.

Step-by-step explanation:

[tex]\sf 34.6 + 118 + x = 180[/tex]

Add 34.6 and 118 = 152.6

What weight would give a newborn a z-score of −0.75? grams

Answers

Using the normal distribution, it is found that a weight of 3125 grams would given a newborn a z-score of −0.75.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Researching the problem on the internet, it is found that the mean and the standard deviation for the weight of newborns is given as follows:

[tex]\mu = 3500, \sigma = 500[/tex]

Hence, the weight associated with Z = -0.75 is given by X:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.75 = \frac{X - 3500}{500}[/tex]

X - 3500 = -0.75(500)

X = 3125.

Answers

Answer:

7 m3

Step-by-step explanation:

Correct

The cement that is needed to build the monument will be 7 m³. Thus, the correct option is B.

What is the volume?

The volume of the rectangular prism is calculated as,

V = LWH

V = 4 m x 0.5 m x 4 m

V = 8 m³

The volume of the triangular prism is calculated as,

V = (BHL) / 2

V = (2 m x 1 m x 0.5 m) / 2

V = 0.5 m³

Since there are two triangular prisms, the total volume of both triangular prisms is:

⇒ 2 x 0.5 m³

= 1 m³

The total amount of cement is calculated as,

⇒ (Volume of rectangular prism - Total volume of both triangular prisms)

⇒ (8m³ - 1m³)

⇒ 7 m³

Thus, the correct option is B.
