Answer:
x/2 + 7 = -4
Step-by-step explanation:
7 more just means plus 7
a quotient of a number and blank basically is 'a number' (usually x) over a the number given if that makes sense. so in our scenario its x/2
'is' basically means is equal to
put it all together and you get x/2 + 7 = -4
hope this helps <3
Answer:
9 x 7 = 63 is cost of 9 people
3 x 9
6 x 8
8 x 8
9 x 7
One possible system of two equations is ...
x = -2
y = -3 .
Answer:
Step-by-step explanation:
From the given information:
We can compute the null hypothesis & the alternative hypothesis as:
The degree of freedom = n - 1
The degree of freedom = 5 - 1
The degree of freedom = 4
At the level of significance of 0.05 and degree of freedom 4,
the rejection region = 9.488
However, we can compute the chi-square X² goodness of fit test as:
months frequency (p) observed O Expected E Chi-square
Dec 0.2 16 16
Jan 0.250 11 20
Feb 0.200 16 16
Mar 0.200 18 16
Apr 0.150 19 12
Total 1.000 80 80 8.3833
∴
The test statistics X² = 8.3833
Thus; we fail to reject the since test statistics X² doesn't fall in the rejection region.
Therefore; there is sufficient evidence to conclude that the distribution of snowfalls in her hometown is not similar to the claimed percentage.
The surface area of a prism is the sum of the lateral area plus the area of the two bases.
<span>LA = p * h </span>
<span>p is the perimeter of the base </span>
<span>For your prism </span>
<span>SA = 2(70) + 50 * 9 = 590 mm^2 <-----OPTION C
