Suppose that in a particular sample, the mean is 70.07 and the standard deviation is 10.27. what is the z score that corresponds

to a raw score of 80?

<span>To find the z score, we need to use the following formula: (raw score - Mean)/ standard deviation. We know that the raw score is 80, the standard deviation is 10.27, and the mean is 70.27, so plugging in those values gives us: (80 - 70.27)/10.27 = 0.9474</span>

The angle formed by the ribbon and the pole is 29°

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let θ represent the angle formed by the ribbon and the pole.

Hence:

sin(\theta)=\frac{7.2}{15} \\\\\theta=sin^{-1}0.48\\\\\theta=29^o

The angle formed by the ribbon and the pole is 29°

Solve the right triangle, ΔABC, for the missing sides and angle to the nearest tenth given angle B = 27° and side c = 15.
nignag [31]

Answer:

Part 1) C=90\°

Part 2) A=63\°

Part 3) b=6.8\ units

Part 4) a=13.4\ units

Step-by-step explanation:

step 1

Find the measure of angle C

we know that

The triangle ABC is a right triangle

so

Angle C is a right angle

therefore

C=90\°

step 2

Fin the measure of angle A

we know that

In the right triangle ABC

∠B+∠A=90° -----> by complementary angles

we have

B=27\°

substitute

27\°+A=90\°

A=63\°

step 3

Find the length side b

we know that

In the right triangle ABC

sin(B)=b/c

b=(c)sin(B)

substitute the given values

b=(15)sin(27\°)=6.8\ units

step 4

Find the length side a

we know that

In the right triangle ABC

sin(A)=a/c

a=(c)sin(A)

substitute the given values

a=(15)sin(63\°)=13.4\ units

In the rhombus m&lt;1 =160. What are m&lt;2 and m&lt;3? The diagram isn't drawn to scale
Zolol [24]
A rhombus is a parallelogram with four equal sides and two sets of equal angles.

If the m<1=160°, then the angle opposite (3) would also be 160°.

m<3=160°.

Becuase it is a parallelogram, the sum of the measurment of two angles that share a line would be 180 (supplementary).

m<2 and m<4 is 20°.
