Answer:
(-2,-1)
Step-by-step explanation:
y=2x+3
y=3x+5
so y=y
then:
2x+3=3x+5
3-5= 3x-2x
-2= X
x=-2
Answer: option A is correct, we accept the null hypothesis.
Step-by-step explanation:
At a 5% level of significance, p = 0.05, therefore when p < 0.05, accept the null hypothesis (H°) and reject the alternative hypothesis (H¡). When p > 0.05, we reject the null hypothesis (H°) and accept the alternative hypothesis (H¡)
Given the p-value to be 0.008, this is less than the 5% threshold, that is, 0.05, hence we accept the null hypothesis.
So we know there are 12 brown ones
brown=12
50 more than 12 is the number of clear bottles so 50+12=62
brown=12
clear=62
30 numbers down from 62 is the number of green ones so 62-30=32
brown=12
clear=62
green=32
12+62+32=106
so Yoshiko collected 106 bottles
Answer:
Step-by-step explanation:
f(x) = 2x^2+ 1
0=2x^2+1
x=4
g(x)= x^2
0=x^2
x^2=0
x=0
