Answer:
n(M) = 4
Step-by-step explanation:
M = (2,4,6,8)
n(M) = Number of values in set M.
n(M) = 4
Answer:
b < -10 and (-∞, -10)
Step-by-step explanation:
I won't draw the number line but I will do the interval notation.
Interval notation is a way to describe infinite or finite sets with numbers.
To solve the inequality first add 2 to both sides to get:
-b > 10 Multiply both sides by -1:
b < -10 is the simplification of the inequality .
Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).
Interval notation: (-∞, -10)
7*7*7 = 343
-> the box is 7 in tall
Answer:
More than 50% would germinate
Step-by-step explanation:
Given that in the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37 of them germinated
Let us check whether more than 50% will germinate using hypothesis test

(right tailed test)
Sample proportion p =
p difference = 0.117
Test statistic Z = p difference/std error = 1.864
p value =0.0312
Since p value <0.05 our significance level of 5% we reject null hypothesis
It is possible to claim that most of the seed will germinate (i.e. more than 50%)
Answer:
A.
Step-by-step explanation:
When you multiply the two binomials using distributive property, you get the answer A. I could display the steps since it did not let me.
