PLS HELPPPP <br><br> 14. IF m1 = (x + 13)°<br> mz2 = 39° AND<br> mz3 = (5x + 4)º.<br> SOLVE FOR X.

forsale [732]

Answer: x=12

Step-by-step explanation:

$m\angle1=(x+13)^0 \ \ \ \ \ m\angle2=39^0\ \ \ \ m\angle3=(5x+4)^0\\$

The sum of the angles of the triangle is 180°:

$(x+13)+39+(180-(5x+4))=180\\\\x+13+39+180-5x-4=180\\\\-4x+48=0\\\\-4x+48+4x=0+4x\\\\48=4x$

Divide both parts of the equation by 4:

$12=x\\\\Thus,\ x=12$

Suppose a normal distribution has a mean of 38 and a standard deviation of 2. What is the probability that a data value is betwe

Dimas [21]

Answer:

P ( 37 < x < 41) = P(-0.5 < Z < 1.5) = 0.6247

Step-by-step explanation:

We know mean u = 38 standard dev. s = 2

We want P ( 37 < x < 41)

so

P( (37 - 38) / 2 < Z) = P(-0.5 < Z)

P( Z < (41 - 38)/2 ) = P( Z < 1.5)

Find P(Z < -0.5) = 0.3085

Find P(Z > 1.5) = 0.0668

so P(-0.5 < Z < 1.5) = 1 - P(Z < -0.5) - P(Z > 1.5)

P(-0.5 < Z < 1.5) = 1 - 0.3085 - 0.0668

P(-0.5 < Z < 1.5) = 0.6247

P ( 37 < x < 41) = P(-0.5 < Z < 1.5) = 0.6247

Find sin(C). round to the nearest hundredth if necessary.

Basile [38]

Answer:

A) 0.38

Step-by-step explanation:

By SOH CAH TOA, the <em>sine of an angle is its opposite side divided by the hypotenuse</em>.

<em>The opposite of ∠C is 5, and the hypotenuse is 13</em>.

So, sin(C) = 5/13 ≈ 0.38.

Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra

mina [271]

Answer:

Akira needs 45 square inches of gold foil to cover the chair free including the bottom

<u>Step-by-step explanation:</u>

Total surface = surface area of the base square + area of 4 triangles

<u>Step 1: The surface area of the base square</u>

surface area of the base = surface area of the square = $s^2$

where s is the side length

The the surface area of the base = $3^2$ = 9 square inches

<u>Step 2: The surface area of the side triangles </u>

The area of the triangle = $\frac{1}{2}\times \text{side length} \times \text{slant height}$

On substituting the values,

The area of the triangle = $\frac{1}{2} \times 3 \times 6$

The area of the triangle = $\frac{18}{2}$

The area of the triangle = 9 square inches

Now the area of 4 triangles = 4 x 9 = 36 square inches

Thus the total surface area = 9 + 36 = 45 square inches
