Helloooo each day she picked 13 tomatoes

4(n)=52

That’s what I put as equation and they want to know how many tomatoes she picked each day which we don’t know so we use it as a n and we know the total 53 so we made equation like this then I divided 53 by 4 and put 13 in n and did the solving and got the same answer

The contents of seven similar containers of sulfuric acid are 9.8, 10.2, 10.4, 9.8, 10.0, 10.2, and 9.6 liters. find a 95% confi
Kamila [148]
The confidence interval is from 9.81 to 10.19.

We first find the mean of the data:

<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10

Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262

The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.

The confidence interval is calculated using
</span>x\pm z\times (\frac{s}{\sqrt{n}})&#10;\\&#10;\\10 \pm 1.96(\frac{0.262}{\sqrt{7}})=10\pm 0.1941<span>

Rearrange the formula S = a/(a - r) for r.
vesna_86 [32]
S = a / (a - r)...multiply both sides by (a - r)
S(a - r) = a
Sa - Sr = a
Sa - a = Sr
(Sa - a) / S = r or it could be : (aS - a) / S = r

Determine if the equation below is a function with independent variable x. If so, find the domain. If not, find a value of x to
Andre45 [30]

Answer:

No because it contains points (3,4) and (3,-4).  You cannot have a x assigned to more than one y-value if you want it to be a function.

Step-by-step explanation:

A function has one output per input.

If we are trying to determine if the given is a function of x, then x is the input.

However I can get two outputs from plugging in x=3.

3^2+y^2=25

9+y^2=25

Subtract 9 on both sides:

y^2=25-9

y^2=16

Take the square root of both sides:

y=\pm \sqrt{16}

y=\pm 4.

So input x=3 yields y=4 and y=-4.

Since this input has more than one output then the given is not a function of x.

----Also!

If you graph the equation, it is a circle with radius 5 and center (0,0). So I could I plug in any number for x between -5 and 5 excluding -5 and 5 which would yield only one output each. Since plugging in either one gives:

(\pm 5)^2+y^2=25

25+y^2=25

Subtract 25 on both sides:

y^2=25-25

Simplify:

y^2=0

There is only one value y such that when you square it gives you 0. That is 0.

x=5 only gives y=0 and x=-5 only gives y=0.

There is no circle, unless it is a circle with radius 0 which means it really wouldn't be a circle, that is a function.

The perimeter of GHJ
Dafna1 [17]
They have a scale factor of 5:6 so first we need to find the perimeter of KLM:
11 + 14 + 17 = 42
Then apply the scale factor of 5:6:
\frac{5}{6}  =  \frac{x}{42}
Set the denominators equal:
\frac{35}{42}  =  \frac{x}{42}
So we see that the perimeter of GHJ is 35.
