Answer:
Step-by-step explanation:
Number of blue marbles = 10
Number of white marbles = 7
Number of Red marbles = 6
Number of Green marbles = 2
Total marbles = 10 + 7 + 6 + 2 = 25
Probability of selecting the blue marble = 10/25 = 2/5

James is standing near the base of a cliff. He spots his friend Jeff at the top. The angle of elevation is 23 degrees. If the cliff is 50 ft high. How far from the base of the cliff is James standing?
Answer:
117.79 ft
Step-by-step explanation:
tan23 = 50/x
(x)tan23 = 50
x = 50/tan23
x = 117.79 ft
Which of the following is a trigonometric identity?
cot 0 + tan 0 = 1
sec2 0 +csc2 0 = 1
tan2 0 = sin2 0 x sec2 0
cos2 = sec2 0 x tank 0
Answer:
it's the first one... I think
Answer:
third one
I'm assuming does 2's are squared symbols.
Step-by-step explanation:
It's the third one because
sin^2 x sec^2 x
sin^2 x (1/cos^2 x) by reciprocal identity
sin^2 x/cos^2 x by multiplicative identity prop
tan^2 x by quotient identity
The first one wouldn't work because plugging in pi/4 gives 1+1=1 which isn't true.
The second one doesn't work because plugging in pi/4 gives 2+2=1 which isn't true.
The last equation doesn't make sense at all. There is no variable on the left and on the right there is an extra variable.
The people at the Cloak soft drink company believe that their brand of drink is favored over their competitor's brand, Pempsi, by the majority of people. A quick survey is conducted to test this belief. Forty people are asked whether they prefer Cloak or Pempsi, and 28 people did prefer Cloak. A statistician at Cloak wishes to construct a 95% confidence interval for the proportion of people that prefer Cloak soft drink. Drag the blue marker from above the words 'lower bound' to the lower bound of the confidence interval on the number line provided. Drag the red marker from above the words 'upper bound' to the upper bound of the confidence interval on the number line provided.
Solution :
[tex]$p = \frac{28}{30}$[/tex]
= 0.93
Given :
[tex]$a=0.05$[/tex]
[tex]$z(0.025)=$[/tex] [tex]$1.96$[/tex] (from standard normal table)
So the lower bound is
[tex]$=p+z\times \sqrt{p \times \frac{1-p}{n}}$[/tex]
[tex]$=0.7+0.93\times \sqrt{0.7 \times \frac{1-0.7}{30}}$[/tex]
= 1.63 + 0.083
[tex]$=1.73$[/tex]

Mrs Mills buys 4 packs of treats for her cats, Fluff and tigger
she gives Fluff 1/6 of a pack each day
She gives tigger 1/5 of a pack each day
for how many complete days will the 4 packs of treats last
Answer: 10 days
Step-by-step explanation:
1/6 + 1/5 = 5/30 + 6/30 = 11/30 (total for the day)
4 / (11/30) = 10.90909091 (divide the total amount of packages by the daily total)
So 10 complete days.

Does the equation below represent a
direct proportion? If yes, identify
the constant of proportionality.
х = 6у
A. No
B. Yes, 36
C. Yes, -6
D. Yes, 1/6
Step-by-step explanation:
The given equation is :
x = 6y ...(1)
Here,
x and y are variables and 6 is a constant number
It means,
x and y are related directly to each other i.e.
x ∝ y
or
x = ky .....(2)
Comparing equation (1) and (2)
k = 6
Hence, yes they are in direct proportion and the value of constant of proportionality is 6.
Answer:
yes / 1/6

solve triangles suing the law of sines
Step-by-step explanation:
In your solving toolbox (along with your pen, paper and calculator) you have these 3 equations:
The angles always add to 180°: A + B + C = 180° ...
Law of Sines (the Sine Rule): When there is an angle opposite a side, this equation comes to the rescue. ...
Law of Cosines (the Cosine Rule):
Find the area of the following
kite:
8 cm
2 cm
2 cm
2 cm
2
A = [?] cm2
Enter
Answer:
Area = 12
Step-by-step explanation:
The perpendicular bisector of the triangle going from upper left to the middle marks the height of the triangle. It's area is found from the standard formula.
Area = b * h / 2
b = 2 + 2 = 4
h = 8
Area = 1/2 * 4 * 8
Area = 1/2 * 32
Area = 16
The smaller triangle is found from all the twos.
b = 2 + 2 same as the larger triangle
h = 2
Area = 1/2 2 * 4
Area = 1/2 8
Area = 4
Total Area = 4 + 16
Total Area = 20
Answer:
Area=20
Step-by-step explanation:
A = 20 cm
