Answer:
This represents 3 and one-third divided by two-thirds because 10/3 = 3 and 1/3.
Negative , you always put the biggest numbers value at the end
Answer:
Since that is a quadratic equation, it will have 2 "x" intercepts.
x^2+7x+2
a = 1 b = 7 c = 2
You would solve for "x" using the quadratic formula.
x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a
x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1
x = [ -7 +- sq root (49 -8) ] / 2
x1 = [-7 + 6.4031242] / 2
x1 = -.29844
x2 = [-7 - 6.4031242] / 2
x2 = -6.7016

Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim
![H_{0} = 45\\H_{1} < 45\\\\](https://tex.z-dn.net/?f=H_%7B0%7D%20%3D%2045%5C%5CH_%7B1%7D%20%3C%2045%5C%5C%5C%5C)
The test statistic :
T = (x - μ) ÷ (s/√(n))
T = (43 - 45) ÷ (15/√70)
T = - 2 ÷ 1.7928429
T = -1.1155
At α = 0.05
Pvalue :
Degree of freedom, df = 70 - 1 = 69
Pvalue = 0.134
Decison region :
Reject
if Pvalue < α
Since Pvalue > α We fail to reject the Null
