2/3 a minus 1/6 equals 1/3 what is a
Answer:
a = 3/4.
Step-by-step explanation:
2a/3 - 1/6 = 1/3
Multiply thru by the LCD 6:
4a - 1 = 2
4a = 3
a = 3/4.

Answer: [tex]3x^{-2.5}[/tex]
Step-by-step explanation:
Given
Expression is
[tex]\dfrac{12\sqrt{x}}{4x^3}[/tex]
Using exponent property [tex]x^a\cdot x^b=x^{a+b}[/tex]
Writing expression in the form of [tex]k\cdot x^n[/tex]
[tex]\Rightarrow \dfrac{12\sqrt{x}}{4x^3}=\dfrac{3\times 4}{4}\times \dfrac{x^{0.5}}{x^3}\\\\\Rightarrow \dfrac{3\times 4}{4}\times x^{0.5-3}\\\\\Rightarrow 3x^{-2.5}[/tex]
sec0 = -[tex]\frac{13}{12}[/tex] and cot0 < 0, find exact values of tan0 and sin0.
Answer:
tan 0 = -2.4
sin 0 = 0.3846
Step-by-step explanation:
sec 0 = -13/12, and cot 0 < 0
the angle 0 is in quadrant II
sec 0 = -13/12 = cos 0 = -12/13 = x/r
=> y = √13²-12²=√169-144=√25=5
so,
tan 0 = y/x = -12/5 = -2.4
sin 0 = y/r = 5/13 = 0.3846
Answer:
Solution given;
Sec θ=-[tex]\frac{13}{12}[/tex]
cotθ< 0,
It lies in second quadrant.
where sin and cosec is positive.
Now
[tex] \frac{1}{cosθ}=-\frac{13}{12}[/tex]
cosθ=[tex]\frac{12}{13}[/tex]
[tex]\frac{b}{h}[/tex]=[tex]\frac{12}{13}[/tex]
b=12
h=13
By using Pythagoras law
p=[tex] \sqrt{13²-12²}=5 [/tex]
Now
exact values of tan θ=[tex]\frac{p}{b}[/tex]=[tex]\frac{5}{12}[/tex]
since it lies in II quadrant
tan θ=-[tex]\frac{5}{12}[/tex]
and
sinθ=[tex]\frac{p}{h}[/tex]=[tex]\frac{5}{13}[/tex]
since it lies in II quadrant
sin θ=[tex]\frac{5}{13}[/tex]

This table shows the number of students at a school in the years 2014-2016, 2014 1,030 students 2015 ? students 2016 1,300 students.In 2015, there were more students than in 2014 but fewer than in 2016. Which could be the number in 2015?
Answer:
it could be the number in 2015 is 2,330
Step-by-step explanation:
Just add the number of the students in 2014-2016.
1,030+ 1,300=2,330

A random sample of 12 families were asked how many kids they had. The data are given below. According to the US Census, families have on average 2.4 kids per family. What is the p-value for the alternative hypothesis that the average number of kids per family is different than the US Census value?
1 1 2 2 2 3 3 3 3 4 4 6
A) p-value = 1.070.
B) p-value = 0.154.
C) p-value = 0.846.
D) p-value = 0.308.
Answer:
0.308
Step-by-step explanation:
Given the data:
1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 6
We need to obtain the sample mean and sample standard deviation :
Sample mean, xbar = Σx/n
Where n = sample size (1+1+2+2+2+3+3+3+3+4+4+6) / 12 = 2.833
Sample standard deviation, s
Using the formula :
s = √Σ((x - xbar)² / n-1)
s = 1.40
Hypothesis :
H0 : μ = 2.4
H1 : μ ≠ 2.4
The test statistic :
(xbar - μ) ÷ (s/√(n))
(2.833 - 2.40) / (1.40/sqrt(12))
Test statistic = 1.0713
Using the Pvalue from Test score calculator :
df = n - 1 = 12 - 1 = 11 ; two tailed
Pvalue(1.071, 11)
= 0.3069
= 0.307

Evaluate cos0 if sin0= sqrt(5)/3
a. 9/5
b. 2/3
c. 5/9
d. 3/2
Solution given:
[tex] \sin( \alpha ) = \frac{\sqrt{5} }{3}[/tex]
so
P=√5
h=3
b=[tex] \sqrt{3 {}^{2} - \sqrt{5} {}^{2} } [/tex]
b=2
so
[tex] \cos( \alpha ) = \frac{b}{h} = \frac{2}{3} [/tex]

What is 5x(4+3.50+6+2.50)
Answer: the answer is 80
Step-by-step explanation: How i got this answer is i followed the PEMDAS order (parenthesis, exponent, multiplication, division, addition, subtraction)
So according to the order, i had to do the parenthesis first, (4+3.50+6+2.50)
(( what i did was i just broke the problems into 2 so it would be much more easier)) (4 + 3.50 = 7.5) and the next (6 + 2.50 = 8.5) Then you would add those numbers together (7.5 + 8.5 = 16)
We can see that we still have the 5 left over, so now all you gotta do is just multiply now. (16 x 5 = 80)
So the answer u r left off with is 80.
