In April, the Messa family gets 800 text messages included in their plan. Together, Tommy and Mary use half of the messages. Jac
laiz [17]

Answer: See explanation

Step-by-step explanation:

Total number of text messages = 800

Amount used by Tommy and Mary = 1/2 × 800 = 400

Number of messages uses by Jack and Stefanie = 240

The expression to find the number of messages Cathy uses will be:

= 800 - (1/2 × 800) - 240

Since the expression is 800 - (1/2 × 800) - 240, the number of messages that Cathy will use will be:

= 800 - (1/2 × 800) - 240

= 800 - 400 - 240

= 160 messages

PLEASE HELPPPPPP!!!!! You are performing an experiment to determine how well plants grow under different light sources. Of the 3
PIT_PIT [208]

The probability that a plant in the experiment receives visible or ultraviolet light is 7/10.

<u>Step-by-step explanation</u>:

The total number of plants in the experiment = 30 plants

Plants that receive visible light alone = 12 plants

Plants that receive ultraviolet light alone = 15 plants

Plants that receive both visible and ultraviolet light = 6 plants

<u>step 1</u> :

<em>Probability = No. of required events / Total number</em>

<u>step 2</u> :

P(visible) = 12 / 30

P(ultraviolet) = 15 / 30

P(both) = 6 / 30

<u>step 3</u> :

P(visible  or ultraviolet) = P(visible)  + P(ultraviolet) - P(both)

                                         = 12/30 + 15/30 - 6/30

                                         = 21/30

P(visible  or ultraviolet) = 7/10

Use calculator to find the values of the following,correct to 3decimal places:<br><br> 1. Cot 61,4
g100num [7]

No such thing as cot (61,4). I think you meant to say cot (61.4°). See the difference?

So, cot (61.4°) is approximately -0.139844.

Rounded to 3 decimal places we get -0.140.
