Answer:
y
Step-by-step explanation:
because every time 7 will multiplied by x it will equals to y. so y will be the constant

Step-by-step explanation:
<u>Step 1: Define</u>
h(x) = -5x + 3
h(5) is x = 5
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function]: h(5) = -5(5) + 3
- Multiply: h(5) = -25 + 3
- Add: h(5) = -22
(–8) • (6) – (5) • (–2)
= (-8*6)-(5*-2)
= (-48)-(-10)
= -48+10
= -38
(–4) • (9) – (5) • (–2)
= (-4*9)-(5*-2)
= (-36)-(-10)
= -36+10
= -26
Evaluate 3(a – 4b) when a = –2 and b = 5.
= 3[-2 - 4(5)]
= 3[-2 -20]
= 3(-22)
= -66
Evaluate 4(a – 3b) when a = –4 and b = 6.
= 4[-4 - 3(6)]
= 4[-4 -18]
= 4(-22)
= -88
Evaluate 5(a – 2b) when a = –3 and b = 5.
= 5[-3 - 2(5)]
= 5(-3 - 10)
= 5(-13)
= -65
Answer:
86.7%
Step-by-step explanation:
For questions regarding values related to a normal distribution, a suitable calculator is required. Numerous calculators, apps, web sites, and spreadsheets are capable of answering this question.
__
One standard deviation above the mean is 327 +27 = 354, so the value is expected to be slightly more than 50% +34% = 84%. It is no surprise, then, that a calculator tells you 86.7% of the data is below 857.
_____
<em>Additional comment</em>
The "empirical rule" tells you 68% of the area is within 1 standard deviation of the mean. The distribution is symmetrical, so half that, 34%, is between the mean and 1 standard deviation above the mean. Of course, 50% of the data is below the mean.
