Total students 5+16+42+22+5 = 90
0-1's probability is 5 / 90 = 5.5% about
2-3's probability is 16 / 90 = 17.7% about
4-5's probability is 42 / 60 = 46.6% about
6-7's probability is 22 / 90 = 24.4% about
8+'s probability is 5 / 90 = 5.5% about
(percentages not rounded, just cut off at the first decimal)

Mary makes biws for floral arrangements she uses 1/8 yard of ribbon for each bow how many bows can she make from two spools that
olga2289 [7]
STEP 1:
Calculate total amount of ribbon
= 2 spools * 24 yards each
= 48 yards total

STEP 2:
Divide total yards (48 yards) by portion size (1/8 yard)

= 48 ÷ 1/8
to divide fractions, we multiply by the reciprocal/inverse of 1/8
= 48 * 8/1
= 48 * 8
= 384 bows

ANSWER: She can make 384 bows.

Hope this helps! :)

Does anyone know the answer?
grigory [225]

Answer:

12.7

Step-by-step explanation:

12.7  

Basically u are gonna wanna use pythagoras first

BC = √(12^2 - 6^2) = √(144 - 36) = √(108) = 10.39230485  

Also the Side Angle Side rule comes into play use the following

BC/sin(55) = CD/sin(90) <----- angle

BC/sin(55) = CD/sin(90) 

sin(90)BC/sin(55) = CD 

1*BC/sin(55) = CD 

BC/sin(55) = CD 

10.39230485/0.819152044 = CD 

12.68666167 = CD 

12.7 = CD

Use the figure below and determine the angle measures. what is the measure of angle G?
bogdanovich [222]

Answer:

45

Step-by-step explanation:

<u>First we want to understand the Base Angles Theorem</u>

The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.

Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.

We can create the equation ∠N + ∠A + ∠G = 180 degrees.

Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into

<em>90 + 2x = 180</em>

We can then solve for x,

<em>90 + 2x - 90 = 180 - 90</em>

<em>2x = 90</em>

<em>2x / 2 = 90 / 2</em>

<em>x = 45 </em>degrees
