Polyatomic ions describes ions which are posses more than one atom. Hence, the formula which represents a polyatomic atomic ion is [tex]SO_{4}^{2-} [/tex]
Sulphates contain both Sulphur and Oxygen atoms, hence, they contain two atoms, thus they are polyatomic. Sulphide are represented as [tex]S^{2-} [/tex] ; containing only Sulphur atom, hence, they are mono atomic. Chlorides are represented as [tex]Cl^{2-} [/tex] ; containing only chlorine atoms, hence, they are mono atomic. Nitrides are represented as [tex]N^{3-} [/tex] ; containing only Nitrogen atom, hence, they are also mono atomic.Therefore, sulphates are polyatomic as they contain more than one atom.

refer to the accompanying data set of mean drive-through service times at dinner in seconds at two fast food restaurants. construct a % confidence interval estimate of the mean drive-through service time for restaurant x at dinner; then do the same for restaurant y. compare the results.
Answers
Step-by-step explanation:
Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.
The standard error is SE = s/√n = 62.6/√50 = 8.85.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
180.56 ± 1.960 × 8.85
180.56 ± 17.35
(163, 198)
Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.
The standard error is SE = s/√n = 49.2/√50 = 6.96.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
152.96 ± 1.960 × 6.96
152.96 ± 13.64

Answers
Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.
How to determine the value of x and y.In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.
x² - 4 = 32 ...........(upper part)
y + y - 4 = y + 6 ....(lower part)
Next, we would solve for x:
x² - 4 = 32
x² = 32 + 4
x² = 36
x = ±√36
x = ±6.
For the value of y, we have:
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 10
y = 16.
