Answer:

B) ∠B

Step-by-step explanation:

We'll name the given acute angle as either ∠ABC or ∠B. This is because, 'B' is the vertex of the given angle, i.e., AB & AC share the same common point → 'B'. Hence, ∠B is the correct option.

Hope it helps ⚜

Can someone please help me find the measure of the exterior angle.
dimulka [17.4K]

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

hram777 [196]

Answer:

Step-by-step explanation:

In a study of the relationship between pet ownership and physical activity in older adults, 586 subjects reported that they owned a pet, while 1931 reported that they did not. Give a 98% confidence interval for the proportion of older adults in this population who are pet owners. Lower limit Incorrect: Your answer is incorrect. Upper limit

p ± z × (1 - p/n)

z = 98%

p = 586/1931

= 0.3034697048

n = 1931

Approximately = 0.3035

Confidence interval =

0.3035 + 2.326 × ( 1 - 0.3035/ 1931)

The diameter of a soccer ball is 8.65 inches. What is the volume of the ball, rounded to the nearest hundredth
yarga [219]
The volume of a sphere is (4πr^3)/3 and since r=d/2, volume of a given sphere with respect to its diameter is:

V=(4πd^3)/24

V=(πd^3)/6  in this case d=8.65 so

V≈338.88 in^3  (to the nearest hundredth)

A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
Snezhnost [94]

Answer:

The answer is " \bold{\frac{2}{3}}"

Step-by-step explanation:

Given set:

\to F \ or\  G = \{ 5,6,7,8,9,10,11,12\}

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

\to P( F\ or \ G) = \frac{8}{12}

                      = \frac{2}{3}

by using the general addition Rule:

\to P(F \cup G) = P(F) +P(G)- P(F \cap G)

                    =\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\
