Answer: Fourth option is correct.

Step-by-step explanation:

Pyrrophyta is the algae which is responsible for causing red tides that can kill thousands of fish.

As we know that Pyrrophyta is a division category of algae consisting yellowish green to golden brown algae.

They are mostly unicellular which form starch and its compounds, and oil as food reserves.

And it includes dinoflagellates which actually cause red tides that kill so many fish.

Hence, fourth option is correct.

Answer:

The correct option are option 2 and option 4

Step-by-step explanation:

From the question we are told that

The sample size is n = 12

The test statistics is $t \approx 1.434$

The level of significance is $\alpha = 0.05$

The rejection region is t>1.796

The null hypothesis $H_o: \mu_d=0$

The alternative hypothesis is $H_a : \mu_d >0$

From the given values we see that t < 1.796(i.e 1.434 < 1.796 ) which implies that t is not within the rejection region

Hence we fail to reject the null hypothesis

The conclusion is that there is insufficient evidence to suggest that that the husbands are significantly older than the wife.

Write an equation of the line with the given slope, m and y intercept (0,b) m=-6, b =-1/2 plss

Arlecino [84]

Recall that an equation in slope-intercept form is as follows:

$y=mx+b,$

where m is the slope of the line, and (0,b) is the y-intercept.

Substituting m=-6, and b=-1/2 we get:

$y=-6x+(-\frac{1}{2})\text{.}$

Simplifying the above result we get:

$y=-6x-\frac{1}{2}\text{.}$

Answer:

$y=-6x-\frac{1}{2}\text{.}$

Cloud [144]

Answer:

The formula: e7 = (b7*d7)+(c7*d7*1.5)

Step-by-step explanation:

Given:

Hours worked = b7

Hourly rate = d7

Overtime hours = c7

Salary calculation = e7

Salary = Hours worked*hourly rate + (overtime*hourly rate)*1.5

Formula

e7 = (b7*d7)+(c7*d7*1.5)

The formula e7 = (b7*d7)+(c7*d7*1.5)

Hope this will helpful to you.

Thank you.
