Answer:
7 > x
Step-by-step explanation:
8-6(x-3) > -4x+12
Multiply 6 with the ones in the paranthesis:
8-6x+18 > -4x+12
Simplify numbers:
26-6x > -4x+12
Do the balance method:
12-26 > -6x+4x
-14 > -2x
Simplify to x:
-14/-2 > -2x/-2
7 > x
Răspuns:
260; 1188; -300; - 260
Explicație pas cu pas:
A.)
26 * (- 12) +26 (-18) + 26,40;
26 (- 12 - 18 + 40)
26 (10)
= 260
C.)
(-18) (-22) + (-18) (-36) + (-18) - 8;
-18 (- 22 - 36 - 8)
-18 (-66)
= 1188
b.)
15 * (- 34) - 15 * 21 + 15 * 35;
15 (-34 - 21 + 35)
15 (- 20)
= - 300
d.)
-26 * (-12) - 26 * (- 18) - 26 * 40.
-26 (- 12 - 18 + 40)
-26 (10)
-260
Answer: 3 different ways
Those three ways, I'll label as A, B, and C
A) Buying the 78 cookies one at a time
B) Buying 6 packs of the 13-count cookies, so 13*6 = 78 cookies total.
C) Buying 2 packs of the 39-count cookies, so 2*39 = 78 cookies total
--------
For option A, we can imagine a rectangle that is 1 unit high and 78 units long giving an area of 1*78 = 78. Or we can imagine a single row of 78 cookies in this row.
In option B, we can have a rectangle that is 13 by 6, giving an area of 78. Or We could have 6 rows of 13 cookies per row (each row representing a package of cookies).
Option C would be similar to B, instead there would be 2 rows of 39 cookies per row.
Answer: d. Do not reject the null hypothesis when it is actually false.
Step-by-step explanation:
A Type II error occurs when we do not reject the null hypothesis when the alternative hypothesis is actually the true statement.
i.e. actually null hypothesis was false but get not rejection.
It is also known as Beta error.
Therefore , the correct answer is A Type II error occurs when we <u>Do not reject the null hypothesis when it is actually false</u> .
Hence, the correct answer : d. Do not reject the null hypothesis when it is actually false
I would look at this as a percent. 23/25 is 92%. To find the percent of a number, make the percent a decimal and multiply. 2,540 times 0.92 is 2,336.8, so therefore the Mississippi is 2,336.8 miles long.
