Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100

Answer:
Your answer is indeed correct. f(-8) = 3
Step-by-step explanation:
[tex]f(x) = -x^{2} - 4x + 35\\f(-8) = -( -8)^{2} - 4(-8) + 35\\f(-8) = -64 + 32+ 35\\f(-8) = 3[/tex]

explain how you can use fractions strips or number lines to show that 3/4 and 6/8 are equivalent.
Answer:
answers is down there
Step-by-step explanation:
you can use fraction strips by using them 3/4 and 6/8 because they are equivalent and that's just life :)
3/4 and 6/8 are equivalent numbers/fractions
The fractions are given as:
[tex]\frac 34[/tex] and [tex]\frac 68[/tex]
To model 3/4 using number lines, we do the following steps
Draw a straight lineDivide into 4 equal segmentsPut a mark at the end of the 3rd pointTo model 6/8 using number lines, we do the following steps
Draw a straight lineDivide into 6 equal segmentsPut a mark at the end of the 6th pointWhen both points are compared, then we find out that:
[tex]\frac 34 \equiv \frac 68[/tex]
Hence, 3/4 and 6/8 are equivalent

Find the equation of a line that has slope, m, of 4 and passes through the point (10, 15).
Step-by-step explanation:
m=4 , (10, 15)
straight line equation:
y= mx +c
substituting the values:
15=4(10) + c
15 = 40 + c
15 - 40 = c
c = -25
therefore,

Actually Welcome to the Concept of the quadratic equations.
Since, as the question told,
=>
[tex] \frac{ {x}^{2} }{3} - 3 = 0[/tex]
hence now solving we get as,
[tex] \frac{ {x}^{2} }{3 } = 3 [/tex]
now, we get as,
[tex] {x}^{2} = 9[/tex]
now, then
[tex] \sqrt{ {x}^{2} } = \sqrt{9} [/tex]
so finally, positive value of x is 3
