Find the slope of a line perpendicular to the line whose equation is 3y + 2x = 6

Charra [1.4K]

$3y + 2x = 6\\ \\the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\3y=-2x+6 \ \ /:3\\ \\y=-\frac{2}{3}x+\frac{6}{3}\\ \\y=-\frac{2}{3}x +2 \\ \\ m = -\frac{2}{3} \\ \\ Answer : \ slope \ is \ m = -\frac{2}{3}$

The owners of Shaving Ice are concerned that many of their customers are starting to purchase their icy treats from Cold as Ice

harkovskaia [24]

Answer:

The correct option is;

$4\pm 2.63}\sqrt{\frac{3.2^{2}}{100}+\frac{2.1^{2}}{100}}$

Step-by-step explanation:

Here we have the formula for the confidence interval of the difference of two means where the population standard deviation is unknown based on the sample mean and sample standard deviation is given as follows;

$\left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2}\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}}}$

Where:

$\bar{x}_{1}$ = Mean of the first sample = 22 grams

$\bar{x}_{2}$ = Mean of the second sample = 18 grams

s₁ = Sample standard deviation of the first sample = 3.2 grams

s₂ = Sample standard deviation of the second sample = 2.1 grams

n₁ = Sample size of the first sample = 100

n₂ = Sample size of the second sample = 100

$t_{\alpha /2}$ = t value obtained from tables at 99% confidence level and 100 degrees of freedom = 2.626 = 2.63

Therefore, plugging in the values, we have;

$\left (22- 18 \right )\pm 2.63}\sqrt{\frac{3.2^{2}}{100}+\frac{2.1^{2}}{100}} = 4\pm 2.63}\sqrt{\frac{3.2^{2}}{100}+\frac{2.1^{2}}{100}}$

Therefore, the correct option is $4\pm 2.63}\sqrt{\frac{3.2^{2}}{100}+\frac{2.1^{2}}{100}}$ .

Beth and Maria are going to the country fair. Admission costs four dollars per person for each day. They plan to go for three da

IRISSAK [1]

The amount one person will pay for a day is $4
The amount two people will pay for a day is $8
The amount Beth paid for 3 days is 4*3=12
The amount Maria paid for 3days is also 4*3=12
So to find the amount they will pay for 3days, add 12 and 12 to get 24.
The girls will pay $24 for the 3days.

Hope it helps
