Answer:
Step-by-step explanation:
Using the following data:
H0:p=0.40 (null hypothesis)
Ha:p>0.40 (alternative hypothesis)
The p-value was determined to be 0.001.
a significance level of 5%
Since the p value (0.001) is less than the significance level (0.05), we will reject the null hypothesis and then we would conclude that the proportion of students that are nursing majors is greater than 0.4.
.90 (ninety cents)
basically what you is you multiply the value of the sweater by the percentage of the tax
Answer:
![\huge\boxed{x=9}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bx%3D9%7D)
Step-by-step explanation:
We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.
![4x + 9 = 45](https://tex.z-dn.net/?f=4x%20%2B%209%20%3D%2045)
Let’s solve for x.
![4x +9-9=45-9\\\\4x=36\\\\x=9](https://tex.z-dn.net/?f=4x%20%2B9-9%3D45-9%5C%5C%5C%5C4x%3D36%5C%5C%5C%5Cx%3D9)

Answer:
The solution of system of equation is (-4,-2)
Step-by-step explanation:
The given system of linear equation is
Equation 1: 2x+y=(-10)
Equation 2: 3x+4y=(-20)
Using the Elimination method:
Important step: First multiply equation 1 by 4
we get,
Equation 3: 4(2x+y)=(-40)
Equation 3: 8x+4y=(-40)
Now,
8x+4y=-40 Equation 3
3x+4y=-20 Equation 2
- - +
________
5x+0=(-40)+20
5x=(-20)
x=(-4)
Replacing value of x i any equation
2x+y=(-10)
2(-4)+y=(-10)
(-8)+y=(-10)
y=(-2)
Thus,
The solution of system of equation is (-4,-2)
