Answer:

[tex]54.75^\circ[/tex]

Step-by-step explanation:

Formula for horizontal distance or range is given as:

[tex]s=\dfrac{2v_i^2sin\theta cos\theta}{g}[/tex]

Where

[tex]v_i[/tex] is the initial velocity

[tex]\theta[/tex] is the angle with horizontal at which the projectile was thrown

[tex]g[/tex] is the acceleration due to gravity.

Given,

Initial velocity, [tex]v_i[/tex] = 60 m/s

Range, [tex]s[/tex] = 300 m

To find: [tex]\theta = ?[/tex]

Solution:

Using the formula as stated above:

[tex]300=\dfrac{2\times 60^2sin\theta cos\theta}{9.8}\\\Rightarrow 2sin\theta cos\theta =\dfrac{300\times 9.8}{3600}\\\Rightarrow sin2\theta =0.81666\\\Rightarrow \theta \approx \bold{54.75^\circ}[/tex]

Firing angle [tex]54.75^\circ[/tex] will produce a range of 300 m.

Answer:

Solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]

Option B is correct option.

Step-by-step explanation:

We need to solve the equation [tex]x^2+6x-8=0[/tex] by completing the square method.

For completing the square method: we need to follow: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

We are given:

[tex]x^2+6x-8=0[/tex]

Solving by completing the square

[tex]x^2+2(x)(?)+(?)^2-8=0[/tex]

We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.

So, adding and subtracting (3)^2

[tex]x^2+2(x)(3)+(3)^2-8-(3)^2=0\\(x+3)^2-8-9=0\\(x+3)^2-17=0\\(x+3)^2=17[/tex]

So, solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]

Option B is correct option.

Answer:

131.1

Step-by-step explanation:

Step 1: Our output value is 460.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$460=100\%$.

Step 4: Similarly, $x=28.5\%$.

Step 5: This results in a pair of simple equations:

$460=100\%(1)$.

$x=28.5\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{460}{x}=\frac{100\%}{28.5\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{460}=\frac{28.5}{100}$

$ x=131.1$

Meaning that 28.5 of 460 is 131.1

Step-by-step explanation:

Answer:

The expected value for the player is -$0.63.

Step-by-step explanation:

The dice game has the following rules:

The outcomes for a sum of 2 or 12 are: {(1, 1) and (6, 6)}

The probability of a sum of 2 or 12 is: 2/36 = 0.055.

The outcomes for a sum of 7 is: {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)}

The probability of a sum of 7 is: 6/36 = 0.167.

The probability of a sum other than 2, 12 or 7 is: 1 - 8/36 = 0.778

The probability distribution is:

        Result          X         P (X)

Sum 2 or 12        $25       0.055

   Sum 7               $2        0.167

   Others             -$3       0.778

    Total                             1.000

Compute the expected value as follows:

[tex]E(X)=\sum x\cdot P(x)\\\\[/tex]

          [tex]=(25\times 0.055)+(2\times 0.167)+(-3\times 0.778)\\\\=1.375+0.334-2.334\\\\=-0.625\\\\\approx -0.63[/tex]

Thus, the expected value for the player is -$0.63.

The graph shows the  function y=sin(1/2x) after a shift of 3 units down .

The Sine Function has this beautiful up-down curve (which repeats every 2π radians, or 360°).

It starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to −1.

According to the question

y=sin(1/2x) after a shift of 3 units down

i.e ,

y + 3 = sin [tex]\frac{x}{2}[/tex]

Now.

x         y

0        -3

π         -2

-π        -4

Graph will be plotted on these points

Hence, the graph shows the  function y=sin(1/2x) after a shift of 3 units down .

Answer: B.236 newspapers

Step-by-step explanation:

Given : Mr. Wilkins delivers 27 papers every day, Monday through Saturday, and 32 papers on Sunday.

i.e. Total newspaper deliver in a week = 27 +32 =59

Then, Total newspapers deliver in 4 weeks = 4 x (Total newspaper deliver in a week)

= 4 x 59

= 236

Hence, 236 newspapers deliver to the homes on Maple Street in 4 weeks.

Answer:

No, because the Central Limit Theorem posits that regardless of the shape of the underlying​ population, the sampling distribution of bar x becomes approximately normal as the sample​ size (n) increases.

The sampling distribution of x is;

[tex]\mu_{\overline x} = \mu = 53[/tex]

Step-by-step explanation:

Given that:

The sample size n = 53

The population mean μ = 53

The standard deviation σ = 7

The sampling distribution of x is;

[tex]\mu_{\overline x} = \mu = 53[/tex]

Sampling distribution of the standard deviation is:

[tex]\sigma _x =\dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]\sigma _x =\dfrac{7}{\sqrt{53}}[/tex]

[tex]\sigma _x =\dfrac{7}{7.28}[/tex]

[tex]\sigma _x =0.96[/tex]
