What is the next number in this sequence?
38 57 76
Answer:
the next sequence is 76+19= 95
Answer:
Next number = 95
Step-by-step explanation:
Hi! Let me help you out.
_________________
To determine the next number in this sequence, we should determine the common difference.
We can do it like this.
[tex]\longmapsto\sf 76-57=19[/tex]
See. I took the third term, and subtracted the second term from it.
Continue.
[tex]\longmapsto\sf 57-38=19[/tex]
↪
The number we obtain after subtracting is the common difference.
So we should take the third term, "76", and add the common difference, "19" to it.
We obtain 95. Which is the final answer.
⇨Hope that this helped you out! have a great day ahead.⇦
Best Wishes!

Use SOHCAHTOA to find the side measure. Show work. Round to one decimal place.
The value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a right angle triangle shown in the picture.
We can use SOHCAHTOA to find the unknown length.
Using the ratio of tan which is opposite to adjacent (TOA)
tan8 = 9/n
n = 64.038 ≈ 64.04
Thus, the value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

Previously, an organization reported that teenagers spent 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2.0. Conduct a hypothesis test.
The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1. The hypothesis can not be concluded.
What is Standard normal distribution?The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.
For the given problems, the Hypothesis mean is 4.5. The sample mean was 4.75 hours with a normal standard deviation of 2.0.
Now, calculating the z-score,
[tex]z = \dfrac{\bar x - \mu_o}{\dfrac{\sigma}{\sqrt n}}\\\\\\z = \dfrac{4.75-4.5}{\dfrac{2}{\sqrt{15}}}\\\\\\z = 0.48[/tex]
Now, as per the standard normal table, the p-value is 0.6844. Since the p-value is greater than the significance level, the hypothesis can not be concluded.
Hence, The hypothesis can not be concluded.

One of the legs of a right triangle is twice as long as the other, and the perimeter of the triangle is 28. Find the length of the hypotenuse.
In a right triangle, the 58-cm hypotenuse makes a 51-degree angle with one of the legs. To the nearesttenth of a cm, how long is that leg?
Evaluate: sin (Arccos(5/13))
Evaluate: tan(Arctan(π/6))
1) If we let the lengths of the legs be x and 2x, then by the Pythagorean theorem,
[tex]x+2x+\sqrt{x^{2}+(2x)^{2}}=28\\3x+x\sqrt{5}=28\\x(3+\sqrt{5})=28\\x=\frac{28}{3+\sqrt{5}} \cdot \frac{3-\sqrt{5}}{3-\sqrt{5}}=21-7\sqrt{5}[/tex]
This means that the length of the hypotenuse is:
[tex]\sqrt{5}(21-7\sqrt{5})=\boxed{21\sqrt{5}-35}[/tex]
2) (Diagram attached) We know that
[tex]\cos 51^{\circ}=\frac{x}{58}\\x=58 \cos 51^{\circ} \approx \boxed{36.5}[/tex] (in cm)
3) From the Pythagorean identity,
[tex]\sin^{2}\left (\arccos \frac{5}{13} \right)+\cos^{2} \left (\arccos \frac{5}{13} \right)=1\\\left(\frac{5}{13} \right)^{2}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\frac{25}{169}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\sin^{2} \left (\arccos \frac{5}{13} \right)=\frac{144}{169}\\\sin \left (\arccos \frac{5}{13} \right)=\boxed{\frac{12}{13}}[/tex]

what is the symbol called ? (i just need the symbol dont solve!)
Answer:
The symbol is a variable called x, which is a mathematical term used to substitute values in mostly linear and quadratic equations.
Answer:
a term.
Step-by-step explanation:
(I'm assuming you're asking about the underlined,)
therefore the 9x is a term
(top line)
the 9 is a coefficient
the x is a variable
5 is a constant
- (subtraction sign) is the operator.
9x - 5 is an expression
(bottom line)
the 3x is also a term
x is the variable
3 is a coefficient
4 is the constant
the + (addition sign) is the operator
3x + 4 is the expression.
the answer would be a constant and a term
hope this helps:)

Answer: An even number between 7 and 16 would be 10.
Step-by-step explanation: I am not sure how I am supposed to draw a picture of the number other than drawing the number itself. However, 10 is an even number because it is a composite number and is divisible by 2. 10 is an even number, not an odd number. Hope this helps!

The vertex of the graph moves to a point twice as far from the y-axis. The vertex of the graph moves to a point half as far from the x-axis. The vertex of the graph moves to a point half as far from the y-axis.
The vertex of the graph moves to a point twice as far from the y-axis.
Option B is the right answer.
What is the equation of Parabola ?The general equation of a parabola is
y = a(x-h)² + k
or
x = a(y-k)² +h
where (h,k) denotes the vertex.
It is given in the question that the value of h is doubled for the equation given
y = a(x-h)² + k
if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore
the vertex of the graph moves to a point twice as far from the y-axis.

if a quarter kilogram costs rs 60 then how much will cost for 150 grams
Answer:
R s. 36
Step-by-step explanation:
1kg ⇒ 1000g
So, a quarter kilogram means,
[tex]\frac{1}{4}[/tex] × 1kg = 1000g × [tex]\frac{1}{4}[/tex]
[tex]\frac{1}{4}[/tex] × 1kg = 250g
According to the question,
250g = R s. 60
So, now they're asking for the price of 150g.
Let that price be x.
250g ⇒ R s. 60
150g ⇒ x
Use cross multiplication to find the value of x.
250x = 60 × 150
250x = 9000
Divide both sides by 250.

8 more than twice Jenny's age
Use the variable j to represent Jenny's age. Please help.. :(
Answer:
2j + 8
Step-by-step explanation:
Given: 8 more than twice Jenny's age
Let j = Jenny's age
"twice Jenny's age" means double (multiply by 2) Jenny's age = 2j
"more than" means to add, so "8 more than" = + 8
Therefore:
"8 more than twice Jenny's age" = 2j + 8
