You have to do this one on your own... on this website you can draw sorry mann
<span>–10 • 2 ÷ (–4) + 8 • 5
</span>
<span>10 • 2 = 20
</span>
<span>8 • 5 = 40
</span>
–10 • 2 ÷ (–4) + 8 • 5 = <span>– 20 ÷ (–4) + 40
The operation Divide ÷ has to be carried out first.
</span>
<span>– 20 ÷ (–4) = -20/-4 = 5
</span><span>– 20 ÷ (–4) + 40 = </span><span><span>5 + 40 = 45</span>
</span>
Option C.
Hope this helps.
Answer:
E. 0.1401
Step-by-step explanation:
The mean here has been given as 20.9
The standard deviation sd = 4.7
Random sample n = 32
Sd/√n
= 4.7/√32
= 0.8309
Probability of x less than 20
= 20-20.9/0.8309
= -0.9/0.8309
= -1.083
P(z<-1.083)
When we go to the z table
= 0.1401
Therefore the probability is 0.1401 and the answer to this question is E.
A b c , d e f
Each letter represents a place value.
a = hundred thousands
b = ten thousands
c = thousands
d = hundreds
e = tens
f = ones
a number that has a double the number of tens as ones.
a b c, d ΔΔ Δ
and three times a number of thousands as hundreds
a b ∞∞∞ , ∞ ΔΔ Δ
The number would be: 3,121
