I need to find the value of x help needed

Answer:

D. The median, 5, is greater than the mean, 4,

Step-by-step explanation:

Median: Put them from least to greatest, ( but they are) then find the middle

Mean: Add all the numbers together= 20, divide that by the numbers you added from 5:    20/5=4

5 from median is < than mean 4

Answer:

m<3=84

m<4=96

Step-by-step explanation:

180-43-41=96

180-96=84

The measure of ∠3 is 96° and measure of ∠4 is 64°.

What is Triangle?

A triangle is a three sided polygon , which has three vertices and three angles with sum 180 degree.

Given that;

In triangle,

Measure of first angle (m ∠1 ) = 43°

Measure of second angle (m ∠2) = 41°

Let measure of ∠4 = x degree

Now, Sum of all angles in a triangle be 180 degree.

So, We can formulate;

m∠1 + m∠2 + m∠3 = 180°

43° + 41° + x = 180°

84° + x = 180°

x = 180° - 84°

x = 96°

So, measure of ∠3 = 96°

Since, The measure of ∠3 and measure of ∠4 are supplementary angles.

Hence, We get;

m ∠3 + m ∠4 = 180°

96° + m ∠4 = 180°

m ∠4 = 180° - 96°

m ∠4 = 64°

Thus, The measure of ∠3 is 96° and measure of ∠4 is 64°.

Answer:

3/2

Step-by-step explanation:

Answer:

1/4 as decimal =0.25

and as percentage 25%

1/ 3 as decimal = 0.33

and as percentage = 33.33%

Using the equation, the time the object will hit the ground after it is launched is 3.4 seconds.

To model the path of a projectile launched from ground level (h = 0), we can set h = 0 in the equation for y:

[tex]y = (v_0sin \theta)t - 16t^2[/tex]

Therefore, the parametric equations for the path of the projectile are:

[tex]x = (v_0cos\theta)t \\y = (v_0sin \theta)t - 16t^2[/tex]

Substituting θ = 40∘ and v0 = 128 feet per second, we get:

[tex]x = (128 cos 40^o)t\\y = (128 sin 40^o)t - 16t^2[/tex]

To determine the maximum height, we need to find the vertex of the parabolic path, which is given by:

t = -b/2a

where a = -16, b = 128 sin 40∘, and c = 0 (since the projectile starts and ends at ground level). Substituting the values, we get:

t = -128 sin 40∘ / (2*(-16)) = 2.3 seconds (approx)

The maximum height can be found by substituting this value of t into the equation for y:

y = (128 sin 40∘)(2.3) - 16(2.3)^2 = 230.3 feet (approx)

Therefore, the maximum height is 230.3 feet and it is reached at 2.3 seconds.

To find the horizontal distance at this point, we can substitute the value of t into the equation for x:

x = (128 cos 40∘)(2.3) = 172.8 feet (approx)

Therefore, the approximate horizontal distance the object is at this point is 172.8 feet.

To determine the time the object will hit the ground after it is launched, we need to find the time when y = 0:

[tex]0 = (128 sin 40)t - 16t^2[/tex]

Solving for t using the quadratic formula, we get:

t = 0 or t = 8 sin 40∘ / 2 = 3.4 seconds (approx)

Therefore, the time the object will hit the ground after it is launched is 3.4 seconds.

Answer:A

Step-by-step explanation:

I used the process of elimination. I did, 125 x .65 to get 81.25. Then, I subtracted 81.25 to 125. To get 43.75.

The original price of the dress was $125.00.

A percentage is a number or ratio that can be expressed as a fraction of 100 in mathematics. If we need to calculate the percentage of a number, divide it by the whole and multiply by 100. As a result, the percentage denotes a part per hundred.

Given that the discount = 65%

Sale price = $43.75

Let the original price of the dress is $x.

Now, sale price = x - x * 65% = x - x * 65/100 = (100 - 65)x/100 = 35x/100

We can write

35x/100 = 43.75

i.e. x = (43.75 * 100)/35 = 4375/35 = 125

Therefore, the original price of the dress was $125.00. So, option 1 is correct.

Answer:

The integers are pairwise relatively prime since two of them are prime

Step-by-step explanation:

Given

[tex]25, 41, 49, 64[/tex]

Required

Determine if they are prime factors

First, we determine the gcd of the 4 numbers

[tex]25 = 1 * 5 * 5[/tex]

[tex]41 =1 * 41[/tex]

[tex]49 = 1 * 7 * 7[/tex]

[tex]64 = 1 * 2 * 2 * 2 * 2 * 2 * 2[/tex]

The common factor in the above computation is: 1

So:

[tex]gcd = 1[/tex]

Because the gcd is 1, this implies that no prime divides all the given numbers.

Hence, they are pairwise relatively prime

x = 80°

Step-by-step explanation:

Recall: an inscribed angle is half the measure of the intercepted arc

Thus:

x = ½(arc cb)

Substitute

x = ½(60)

x = 30°

x = ½(arc ab)

Substitute

x = ½(160)

x = 80°

Answer:

6.14 minutes   or   6 minutes & 8.4 seconds

Step-by-step explanation:

Initial elevation: 453 ft

Final elevation: 146 ft

Difference in elevation: 453 ft - 146 ft = 307 ft

speed = 50 ft/min

speed = distance/time

time * speed = distance

time = distance/speed

time = (307 ft)/(50 ft/min)

time = 6.14 minutes = 6 minutes + 0.14 * 60 seconds

time = 6.14 minutes = 6 minutes + 8.4 seconds

Anwner : 4/52

Explanation : The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221.

c) [tex]\frac{x-2}{x+6}[/tex]

Step-by-step explanation:

When given that function (f) is the following,

[tex]f(x)=\frac{x+2}{x^2+4x-12}[/tex]

The wisest move to first make is to factor the expression, factoring is the process by which one rewrites a quadratic expression as the product of two linear expressions,

[tex]f(x)=\frac{x+12}{(x+6)(x-2)}[/tex]

If is given that function (g) is the following,

[tex]g(x)=\frac{4x^2-16x+16}{4x+48}[/tex]

Then one should also factor the expression,

[tex]g(x)=\frac{4(x-2)^2}{4(x+12)}[/tex]

One is asked to find the following,

[tex]f(x)*g(x)[/tex]

To do this operation, one must multiply the two functions together. It is easiest to do so when the functions are in factored form,

[tex]f(x)*g(x)[/tex]

Substitute,

[tex](\frac{x+12}{(x+6)(x-2)})(\frac{4(x-2)^2}{4(x+12)})[/tex]

Simplify, cross out like terms in the numerator and denominator,

[tex]\frac{x-2}{x+6}[/tex]

Answer:

The appropriate solution is "95%".

Step-by-step explanation:

The given values are:

Lower bound,

= 173.8

Upper bound,

= 196.2

Mean of cholesterol,

= 138 milligrams

S = 17.6 mg

Now,

The margin of error (E) will be:

=  [tex]\frac{Upper \ bound-Lower \ bound}{2}[/tex]

=  [tex]\frac{196.2-173.8}{2}[/tex]

=  [tex]\frac{22.4}{2}[/tex]

=  [tex]11.2[/tex]

As we know,

⇒  [tex]E=t_{\alpha 12}\times \frac{S}{\sqrt{n} }[/tex]

On putting the values, we get

⇒   [tex]11.2=t_{\alpha 12}\times \frac{17.6}{\sqrt{12} }[/tex]

On applying cross-multiplication, we get

⇒   [tex]t_{\alpha 12}=2.2044[/tex]

∴ [tex]\frac{\alpha}{2} =0.025[/tex]

   [tex]\alpha = 0.025\times 2[/tex]

      [tex]=0.05[/tex]

hence,

The confidence level will be:

⇒  [tex]CI=1-\alpha[/tex]

⇒        [tex]=1-0.05[/tex]

⇒        [tex]=0.95[/tex]

⇒        [tex]=95[/tex]%
