<span>△PQR is similar to △STU

</span>m∠R = m∠U = 96°

m∠Q = m∠T = 6

m∠P = 180 - ( 96 + 6)

m∠P = 180 - 102

m∠P = 78
 
answer 

m∠P = 78

Answer:

m\angle P=12^{\circ}

Step-by-step explanation:

Two triangles are similar if their angles are equal one to one.

So:

m\angle P= m\angle S\\m\angle Q= m\angle T\\m\angle R= m\angle U

Also, the problem provided this data:

m\angle T= 6(m\angle P)

As you may know, the sum of the interior angles of a triangle is equal to 180, so:

m\angle S+m\angle T + m\angle U=180\\\\Where:\\\\m\angle T=6(m\angle P)\\\\So:\\\\m\angle S+6(m\angle P) + m\angle U=180

and:

m\angle P=m\angle S\\\\Hence\\\\m\angle S+6(m\angle S) + m\angle U=180\\\\7(m\angle S) + m\angle U=180\\\\7(m\angle S) + 96=180

Solving for m\angle S

m\angle S =\frac{180-96}{7} =12^{\circ}

Since:

m\angle P= m\angle S=12^{\circ}

Therefore m\angle P=12^{\circ}

Carol Ann buys a TV at 70% off the original price. If she pays $120, what was the original price of the TV?
Keith_Richards [23]
If the TV is 70% off, then that means she paid 30% of the original cost.  If 30% of the original cost  is $120, then...

30% * x = 120
.30x = 120
x = 120/.30
x = 400

The original cost was $400

ruslelena [56]

Answer: provided in the explanation segment

Step-by-step explanation:

(a). from the question, we can see that since that б is known, we can use standard normal, z.

we are asked to find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error?

⇒ 80% confidence interval for the average weight of Allen's hummingbirds is given thus;

x ± z * б / √m

which is

3.15 ± 1.28 * 0.32/√10

= 3.15 ± 0.1295 = 3.0205 or 3.2795

(b). normal distribution of weight (c) б is known

(c). option (a) and (e) are correct

(d).  from the question, let sample size be given as S

this gives';

1.28 * 0.32/√S = 0.15

√S = (1.28 * 0.32) / 0.15 = 2.73

S = 7.4529
