What is the value of x in the equation x - y = 30, when y = 152 4 8 80 200

Evaluate the six trigonometric functions of the angle 0

yarga [219]

Answer:

sin=The sin of an acute angle is defined in the context of a right triangle.

csc= The length of the hypotenuse divided by the length of the side opposite the angle.

cos= The length of the adjacent side divided by the length of the hypotenuse.

sec 0=The ratio of the length of the hypotenuse to the length of the adjacent side is the secant of an angle in a right-angled triangle.

tan A=In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A).

cotA= In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side.

For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard dev

topjm [15]

Answer:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$

Step-by-step explanation:

For this case we have the following parameters given:

$\mu = 9.2 , \sigma =1.6$

We select a ample size of n=49. And we want to find this probability:

$P(\bar X> 9.3)$

And for this case is a right tail probability and we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$

The diagram represents a reduction of a triangle by using a scale factor of 0.8.

Alekssandra [29.7K]

Answer:

4.8 inches

Step-by-step explanation:

See comment for complete question

Represent the larger triangle with 1 and the smaller with 2.

So, we have:

$H_1 =6\ in$ -- height of 1

Required

Determine H2 --- Height of 2

To do this we apply dilation formula.

$Original * Scale\ Factor = New$

In this case:

$H_1 * Scale\ Factor = H_2$

Substitute 6 for H1 and 0.8 for Scale Factor

$6* 0.8 = H_2$

$4.8= H_2$

Hence, the height of the smaller triangle is 4.8 inches
