Answer:
The error interval for x is:
[3.65,3.74]
Step-by-step explanation:
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]

1. 4 squared Meaning 4 x 4 = 16
2. 16 x 6 = 96
3x 6 = 18
96- 18 = 78

Find Arc measure of ABC
Answer:
268°
Step-by-step explanation:
[tex] In\: \odot O, [/tex] AB is diameter.
So, [tex] \widehat{AB} \:\&\: \widehat {BA}[/tex] are semicircular arcs.
[tex] \therefore m\widehat {AB} =m\widehat {BA} = 180\degree [/tex]
[tex] \because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA} [/tex]
[tex] \therefore \: m\widehat {BC} = (180-92)\degree [/tex]
[tex] \therefore \: m\widehat {BC} =88\degree [/tex]
[tex] \because m\widehat {ABC} = m\widehat {AB}+m\widehat {BC} [/tex]
[tex] \therefore m\widehat {ABC} = 180\degree+88\degree [/tex]
[tex] \therefore m\widehat {ABC} = 268\degree [/tex]
Give a polygon with 13 sides, find sum of the measure of its interior angles. a polygon with 13 sides has an interior angle measure sun of
Answer:
sum of interior angles is 1980°
Step-by-step explanation:
(n-2)×180° = (13-2)×180°
= 11×180°
= 1980°
Answer:
1980 Degrees
Step-by-step explanation:
By Now You Must Know To Use The Equation:
(n-2)180
The 13 is n so now it is:
(13-2)180
13-2 is 11
So Now It Is
11 x 180
And Now The Answer Is 1980
-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?
In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

7th Grade math if anyone knows
Answer:
30° and 150°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 1 + 5 = 6 parts
Divide 180° by 6 to find the value of 1 part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
5 parts = 5 × 30° = 150°
smaller angle = 30°
larger angle = 150°

Answer:
11 73/78 ≈ 11.9359 (not 14)
Step-by-step explanation:
The similarity statement tells us ...
QS/QR = FG/FH
QS = QR·FG/FH
13x -14 = 154(55/60) = 847/6
Adding 14 = 84/6, we have ...
13x = 931/6
x = 931/78 = 11 73/78 . . . . . . . divide by 13
__
Comment on the question
You get a nice integer answer for x if the similarity statement is written ...
∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order
Then you have ...
QS/QR = FH/FG
13x -14 = 154(60/55) = 168
13x = 182
x = 14
This nice answer to a nice similarity statement leads us to believe the question has an error in it.
We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question as written. You may want to discuss this with your teacher.

Scientists measure a bacteria population and find that it has 10,000 organisms. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after scientists first measured it, assuming it grows exponentially?
Answer:
f(x)= 10,000(2)^x
Step-by-step explanation:
Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.
A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]
What is an exponential growth?An exponential growth function is a function that grows at a constant percent growth rate.
What is an exponential growth function?f(t) = a×(1 + r)^(t)
where f(t) = exponential growth function
a = initial amount
r = growth rate
t = number of time intervals
For given example,
initially a bacteria population (a) = 10,000
Five days later, they find that the population has doubled.
d = 5, f(5) = 20,000
Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.
[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]
This means, the exponential growth function would be,
[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.
