Answer:
2 YERAS AND 5 MONTHS
Step-by-step explanation:
90 = <u>910 X 4.1 X T </u>
100
90X100 = 3731 X T
9000 = 3731T
T = 2.4
2 YEARS AND .4X 12 = 5 MONTHS
IN 2 YEARS AND 5 MONTHS THE ACCOUNT WILL GROW TO $1,000
Hello there!
First, let's simplify our second ratio, 12:60.
They both can be divided by 12, so let's simplify.
1:5 to 5:m
This means 1:5 multiplied by 5 to get 5:m, so we need to multiply the "5" in 1:5 to get m.
5 x 5 = 25
m = 25
I hope this helps!
Answer:
x=3⋅± 2
=±4.2426
x=0
Step-by-step explanation:
Hello there! Let’s start with #17 through steps:
1. Add 25 to both sides
-25 + 25 = 0
8 + 25 = 33
2. Simplify
2x = 33
3. Divide by 2
2 divided by 2 equals x
33 divided by 2 equals 16.5
Your final answer: x = 16.5 OR 33/2
Now, onto 18!
Given that y = 2:
1. Plug 2 in
3x = 4(2) + 8
3x = 8 + 8
2. Simplify
3x = 16
3. Divide by 3
3 divided by 3 equals x
16 divided by 3 equals 5.3333
Your final answer: Given y = 2, this means x = approximately 5.3333.
Hope this helps!
Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ;σ²)
= 6
X[bar]= 158.17
S= 19.87
The hypothesis is:
H₀: μₓ = μ
H₁: μₓ ≠ μ
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]) - (μₓ - μ)]/[Sa/√(1/nₓ + 1/)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
