Answer:

180°

Step-by-step explanation:

The sum of the measures of the interior angles formed by the boundary of this team pennant.

The shape of pennant is similar to triangle. It means pennant has 3 sides and 3 angle.

It would be triangle. As we know, the sum of measure of interior angles of a triangle is 180°

∠1 + ∠2 + ∠3 = 180°

Hence, The sum of measure of angles formed by boundary of pennant is 180°

I think the correct answer from the choices listed above is option C. The <span>sum of the measures of the interior angles formed by the boundary of this team pennant should be 180 degrees since all triangles has a sum of interior angles which is 180 degrees. Hope this answers the question.</span>

A shelf is designed so it will fit in a 90º corner between two walls. The shelf has dimensions, rounded to the nearest tenth, as
den301095 [7]

Answer:

Yes, it will fit snugly in a 90º corner

Step-by-step explanation:

To do this, we simply need to check if the given sides of the shelf is right-angled.

So, we have:

Hypotenuse = \sqrt{242

Side\ 1 = Side\ 2 = 11

To check for right-angle triangle, we make use of:

Side\ 1^2 + Side\ 2^2 = Hypotenuse^2

This gives:

11^2 + 11^2 = \sqrt{242}^2

121 + 121 = \sqrt{242}^2

242 = \sqrt{242}^2

242 = 242

This shows that the given sides of the shelf is a right-angled triangle.

Hence, it will fit the wall

In a statistics class there are 18 juniors and 10 seniors; 6 of the seniors are females and 12 of the juniors are males. If a st
White raven [17]

Answer:

a) 0.857

b) 0.571

c) 1

Step-by-step explanation:

Based on the data given, we have

  • 18 juniors
  • 10 seniors
  • 6 female seniors
  • 10-6 = 4 male seniors
  • 12 junior males
  • 18-12 = 6 junior female
  • 6+6 = 12 female
  • 4+12 = 16 male
  • A total of 28 students

The probability of each union of events is obtained by summing the probabilities of the separated events and substracting the intersection. I will abbreviate female by F, junior by J, male by M, senior by S. We have

  • P(J U F) = P(J) + P(F) - P(JF) = 18/28+12/28-6/28 = 24/28 = 0.857
  • P(S U F) = P(S) + P(F) - P(SF) = 10/28 + 12/28 - 6/28 = 16/28 = 0.571
  • P(J U S) = P(J) + P(S) - P(JS) = 18/28 + 10/28 - 0 = 1

Note that a student cant be Junior and Senior at the same time, so the probability of the combined event is 0. The probability of the union is 1 because every student is either Junior or Senior.

Natasha_Volkova [10]

Answer:

286

Step-by-step explanation:

Given that:

For every 13 people who prefer football ; 7 prefer basket ball

At an event;

Number who prefer basketball = 154

Number who prefer football :

[(Total who prefer basketball) ÷ 7] * 13

(154 / 7) * 13

= 22 * 13

= 286
