First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped
8x45
8(40)+8(5)
320+40
360
Conversions: to smallest (inches)
n= 22 inches
b= 2 1/3 yard = 84 inches
t= 12 1/2 feet = 150 inches
total space = t
night stand = n (2n for two nightstands)
bed=b
b+2n has to be < or = to t
84+2(22)=x
84+44=128
128 is < 150
therefore the answer is yes they will fit with 22 inches left over.
Answer:
a) The level of significance is large because here z is not appropriate.
b) The true critical value is larger than z because the level of significance is large.
Step-by-step explanation:
a) Based on the question under consideration, the true level of significance is larger than .05 level of significance is large, the reason being that z is not appropriate in this case.
b) The true critical value is larger than that of the critical z, this is because the level of significance is large.
t* in P(T > t*) = 0.975 is more than z* = 1.96 in P(z> z*) =0.975
Answer:
(3,2)
Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13
