plssss help me i'll give u 40 points evaluate: 3/5^-2
Answer:
75
Step-by-step explanation:
5^-2 = 5*5 = 25/1
because it's (-) you need to flip it so 1/25
3/1 ÷ 1/25 = 3/1 × 25/1
because when you divide fraction you need to keep the first fraction as it is and change the symbol from (÷) to (×) and flip the second fraction. (KCF simple way to memorise it)
So 3/1 × 25/1 = 75/1
75/1 is same as 75

Tia mixes mashed pumpkin with several other ingredients to make homemade treats for her dog. She uses 3/4 cup of pumpkin to make 1 1/4 pounds of treats. How many mashed pumpkin does Tia use to make 1 pound of treats?
Step-by-step explanation:
Use a comparison method!!
3/4 : 1 1/4 = x : 1
3/4 : 5/4 = x : 1
3/4 × 1 = x × 5/4
3/4 = 5x/4
x = 3/4 ÷ 5/4
x = 3/4 × 4/5
x = 3/5
Tia used 3/5 cup of pumpkin to make 1 pound of treats

A test statistic is a statistic that is used to test statistical hypotheses. The test statistic of the given hypothesis is; C: -0.25
What is the test statistic?A test statistic is a statistic that is used to test statistical hypotheses. A test statistic is a numerical summary of a data set that lowers the data to a single number that can be used to perform the hypothesis test.
As it is given to us that the sample mean(x') is 36.63 hours, while the standard deviation(σ) is 13.23.
Now, we want to know whether Americans work less than 40 hours or not. therefore, let's first define the hypothesis;
Alternative Hypothesis; μ < 40
Null Hypothesis; H₀: μ ≥ 40
Further, the Formula for test statistics is given,
[tex]z = \dfrac{(x'-\mu)}{\sigma}\\\\z = \dfrac{(36.63- 40)}{13.23}\\\\z = -0.25[/tex]
Hence, the test statistic of the given hypothesis is; C: -0.25.

Hello! I have a project where I invite 5 people to a “dinner party” to school. I want to invite a girl named Jaci Butler. Jaci Butler is her own agent in the singing industry. I found her address and want to send her a mail inviting her to the party. The party is at school. Does this count as stalking? If you were Jaci butler, what would you think I’m a stalker? If you were her, would you come?
REMEMBER: IM NOT INVITING HER TO MY HOUSE. IM INVITING HER TO MY SCHOOL
It's s tu pid if you really consider the question. No one hosts a 'dinner party' at school.. & that too with just 5 people. Utter ma dness, but if you really do invite an A-list celeb then she won't come unless there are audiences (in a huge number), other celebs, reporters etc. Plus you'll also need prior appointment. If you have all these then it's not sta lki ng..but that's not what happens in a dinner party & it's gonna cost a lot of money too. Now, this Jaci Butler you talk of is a singer-songwriter & you tuber..might not be a really big celeb (like Taylor Swift or Arianna Grande) or something but still calling her late at night to a school with 5 people sounds we ird & while it's not considered as s ta lking to me ...no person in their right mind would actually do it. St alking is like when you follow a person around making the other person uncomfortable with your presence. You hardly did that in this case...but calling Jaci to a dinner party at school is still c re epy. So, if I were Jaci I sure wouldn't come.
Peace ✌ ☮
