I need help with math

Answer:

Step-by-step explanation: You just need to do the normal problem which will equal the numerator and then you have to divide it by 5

Answer:

I got 6.7 but I'm not entirely sure

Step-by-step explanation:

Pythagorean Theorem is A² + B² = C²

So you take 6² + 3² = 45

Take 45 and square root it

The answer should be 6.708, but rounding to the nearest tenth, the answer is 6.7

I Think the answer is D!! Please mark me brainliest! Thank you in advance!

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)

Answer:

true

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) 5/12

To make the denominator to 36, 12 should be multiplied by 3. As we are multiplying the denominator by 3, numerator also should multiplied by 3

[tex]\frac{5}{12}=\frac{5*3}{12*3}=\frac{15}{36}[/tex]

2) 1/6

[tex]\frac{1}{6}=\frac{1*6}{6*6}=\frac{6}{36}\\[/tex]

3) 7/9

[tex]\frac{7}{9}=\frac{7*4}{9*4}=\frac{28}{36}[/tex]

Answer:

5 porque 3 mas 2 es 5, 4 mas 1 es 5

Answer:

60

Step-by-step explanation:

Answer:

that would be 70%

Step-by-step explanation:

Answer:

16^2 = 8^2 + x^2

x^2 = 16^2  -8^2

x^2 = 256 -64

x^2 = 192

x = sq root (192) =  13.8564064606

i don't know if this is right, if it is wrong i'm sorry, but basically it is 12.7m

Answer:

20x-21y+14

Step-by-step explanation:

1/5(100x-105y+70)

20x-21y+14

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 :)

Answer:

[tex]3-\sqrt{10}[/tex]

Step-by-step explanation:

We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :

[tex]\sqrt{5} *\sqrt{2}[/tex]

[tex]\sqrt{10}[/tex]

Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

[tex]3-\sqrt{10}[/tex]

Answer:

I think it’s 360

Step-by-step explanation:

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%
