Answer:
2x - 7y + 17
Step-by-step explanation:
Subtracting the 2 expressions
2x - 4y + 6 - (3y - 11) ← distribute parenthesis by - 1 )
= 2x - 4y + 6 - 3y + 11 ← collect like terms
= 2x - 7y + 17

Answer:
The correct option is: b) the test would also be statistically significant at level alpha = 0.10
Step-by-step explanation:
Consider the provided information.
Suppose a medical researcher conducts a statistical test of hypotheses and finds there is statistically significant evidence for the alternative hypothesis at a significance level alpha = 0.05.
It means that the test would be statically significant at level alpha = 0.10
As we know that if alternative hypothesis is true then the value of p must be less than α.
That means if the p-value is less than 0.05 then it must be less than 0.10.
Hence, the correct option is: b) the test would also be statistically significant at level alpha = 0.10
Answer:
8y=21x
Step-by-step explanation:
i'm not sure how to draw this out in a picture but the equation is above.
like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.
in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.
hope this helps, if it did please make sure to leave a like, rate, and give me the brainliest if possible!
thanks have a great day!
