Answer:
The Civil Rights Act of 1964 contained provisions barring discrimination and segregation in education, public facilities, jobs, and housing
Explanation:
The civil rights movement that happened during the 1960s was simply a struggle for social justice to enable black people in the US gain equal rights under the United States of America laws.
The movements led to the enactment of Civil Rights Act in June 1964. President John F. Kennedy was the sitting president at that time who sent the bill to the congress a year earlier. The Southern segregationist senators stalled the process and when president Kennedy was killed, Lyndon Baines took over and and ensured the bill was passed.
The act contained certain provisions that prohibits discrimination and segregation in education, public facilities, jobs, and housing. It made for Equal Employment Opportunity Commission creation which ensured fair hiring practices.
The balance that can be used to measure a mass reading of 6.521 g will be a balance with ±0.001 g tolerance.
<h3>What is the tolerance of a balance?</h3>
The tolerance of a balance is the number of decimal place values displayed on the balance and it is the acceptable measurement limitations (in grams) that a balance can tolerate.
- As such, depending on the decimal place value behind a mass reading will determine the balance used for measurement.
Since no mass reading was given, let's make two assumptions about mass reading.
Mass reading Assumptions
1 6.521 g
2 4.23 g
- The balance used for the 6.521 g mass reading is a balance with ±0.001 g tolerance.
- The balance used for the 4.23 g mass reading is a balance with ±0.01 g tolerance.

Florida was controlled by Spain following its colonization amidst the Spanish colonization of the Americas. However, it was traded to the British in 1763.
Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
![r=\frac{sum(x-xbar)(y-ybar)}{\sqrt{sum(x-xbar)^2sum(y-ybar)^2} }](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bsum%28x-xbar%29%28y-ybar%29%7D%7B%5Csqrt%7Bsum%28x-xbar%29%5E2sum%28y-ybar%29%5E2%7D%20%7D)
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
![r=\frac{-6}{\sqrt{23.2(8)} }](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-6%7D%7B%5Csqrt%7B23.2%288%29%7D%20%7D)
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
