Answer:
You need to get a 95 on the next test to have a 90 grade average.
Step-by-step explanation:
(85 + 90 + n)/3 = 90
<u>Step 1: Multiply both sides by 3</u>
(85 + 90 + n)/3 * 3 = 90 * 3
85 + 90 + n = 270
<u>Step 2: Subtract 85 from both sides</u>
85 + 90 + n - 85 = 270 - 85
90 + n - 90 = 185 - 90
n = 95
Answer: You need to get a 95 on the next test to have a 90 grade average.
The one you picked, on the bottom left is correct
The top two both have rectangles and triangles, making them most likely triangular prisms. To the bottom right, the net represents a cube, which is incorrect, because the figure is supposed to be a rectangular prism.
Answer:
As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,
'800+900×25-65(89-5)-12÷67-7'
Solving the bracket gives us:
'800+900×25-65(84)-12÷67-7'
Now avoiding the Bracket:
'800+900×25-5460-12÷67-7'
Now first we have to do MUltiplication, so we will get,
'800+22500-5460-12÷67-7'
Now let's do the division, so we will get,
'800+22500-5460-0.17-7'
Now lets do the additions and subtractions we will get,
<h2><u>17,832.83</u></h2>
Answer:
The confidence interval is 
Step-by-step explanation:
We have given,
The Z interval (23.305,25.075)
Mean 
Sample n=30
To find : The confidence interval?
Solution :
We know, The confidence interval is in the format of

E denotes the margin of error,

Where, U is the upper limit U=25.075
L is the lower limit L=23.305



Substitute the value of E and
in the formula,


Therefore, The confidence interval is
