Answer:

x= 11.25, y=5.29

Step-by-step explanation:

Since I can only guess what subject this is off the picture, I've concluded by dividing 90 with the bigger triangle's side will give you your hidden answer. For example, 90/15 = 6 so I'd presume the rest are like that. 90/17 = 5.29, 90/8 = 11.25

9. There are 150 fruits on a market stall.
54 are oranges and 72 are apples and the rest are pears.
What percentage of the fruit are pears?
You must show your calculations. 015)
(2 Points)

Answers

Answer:

24%

Step-by-step explanation:

150 = 54 + 72 = 126 + 24 = 150

24/100 = 24%

Ahhh...first we need to find out the percentage of the oranges+the apples. then take it away from 100%.

I did a bit of tinkering and figured out that the orange percentage is 36% of it.

([tex]\frac{150}{54} =\frac{75}{27} =36%[/tex]%)

That means that the apples are 48% and the pears are 100-(36+48)=100-84=16%

1. Find the 90% Cl for the population mean if sample
mean= 12, SD=2.3 and sample size is 65.
2. Find the 88% Cl for the population mean if sample
mean=23, SD=12, and sample size is 45.
3. Interpret #1 and #1.

Answers

Answer:

The answer is below

Step-by-step explanation:

1)

mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65

Given that the confidence level (c) = 90% = 0.9

α = 1 - c = 0.1

α/2 = 0.05

The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47[/tex]

The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)

2)

mean (μ) = 23, SD(σ) = 12, sample size (n) = 45

Given that the confidence level (c) = 88% = 0.88

α = 1 - c = 0.12

α/2 = 0.06

The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8[/tex]

The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)

Answers

Answer:

Step-by-step explanation:

yes,  as below

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

in the picture there is a Hyp and an Opp

so, use the function that has those  sin has those , huh

then,  

sin(Ф) = 12/13

Ф = arcSin(12/13)

Ф = 67.38 °

now we know that angle.. now we can get cos

cos(67.38 °) = adj / 13

13 * cos(67.38 °)  = adj

oh it's exactly

5 = adj

I feel like that's right since it worked out to be exactly 5  :)

Cos(Ф) = 5 / 13

there is  your answer :)
