To determine whether each sentence has a double negative, an incorrect intensive pronoun, or slang, let's analyze each sentence individually:

A. Because I studied, the test was no sweat.
This sentence does not contain a double negative, incorrect intensive pronoun, or slang. It is grammatically correct and does not have any informal language.

B. The amusement park was cool!
This sentence contains slang. The word "cool" is informal and colloquial in this context.

C. The manger hisself took the mop and cleaned up the mess.
This sentence contains an incorrect intensive pronoun. The word "hisself" is not a standard English pronoun. The correct pronoun would be "himself."

D. We didn't tell nobody about the broken window.
This sentence contains a double negative. The words "didn't" and "nobody" create a double negative, which can be grammatically incorrect in standard English. The correct sentence should be "We didn't tell anybody about the broken window."

E. She couldn't hardly fit the book in her purse.
This sentence contains a double negative. The words "couldn't" and "hardly" create a double negative, which is grammatically incorrect. The correct sentence should be "She could hardly fit the book in her purse."

In summary,
Sentence A: No errors.
Sentence B: Contains slang.
Sentence C: Contains an incorrect intensive pronoun - "hisself."
Sentence D: Contains a double negative - "didn't" and "nobody."
Sentence E: Contains a double negative - "couldn't" and "hardly."
